View Full Version : Good Track Brake Pads Which Don't Squeal Too Much?

The Glen finished off the stock front brake pads in our Cayman R, so we replaced them with a spare set of Hawks which somebody at the DE had handy. The Hawks have far better bite than the stock pads, and I generally like them better than the stock pads, but their squeal is incredibly loud on the street, to the extent that they're effectively unstreetable.
I'd appreciate recommendations regarding track pads which don't squeal excessively on the street.

Please try a search, as there are quite a few threads on this already.
But really there are no effective track pads that will not squeal. So if you want quiet on the street, you will need a set of street pads and a set of track pads.

Thanks, I'll do some searching. By the way, the pads are Hawk HT-10s.

As David suggested, search is your friend.
But fundamentally, most street pads designed for noise free and low dust, are just not capable of withstanding the rigors of high speed, repeated stops (= lots of heat!). I've seen a set of new street pads that were down to the backing plate after 3 hard sessions on the track.
Track pads are designed for the abuse of track driving. Part of this is withstanding the heat, and why they seem to do well and stay quiet when used on the track. But then at slower speeds, they don't get hot enough to work properly, and they tend to squeak. In fact, I'm actually amazed at how well modern track pads will stop nowadays at street speeds. When I ran my 240Z back in the '80's, the track pads (Ferodo's) were great on the track, but were literally unsafe for street driving. When cold, they had almost no stopping power. First lap on track was spent dragging the brake in order to warm them up.
As far as dust, I guess it has something to do with the material composition needed to make them effective at high-temp/abusive conditions. I've yet to see a decent track pad that keeps your wheels/car clean.

Listen to Hoodpin.
Pads that work well on the street are soft and silent, pads that work on the track are harder and NEED to be hot to work properly. While street pads are OK for the first days of green, they won't survive once you start using the brakes on track.
Resign yourself to having both street and track pads.
FWIW, I drove to every event for two seasons on R comp rubber with track pads. Its hard to sneak out of a hotel carpark early when the brakes squeal like a banshee.

It will be quicker to age to the point where you lose your high frequency hearing. If you find track pads that don't squeal during street use before that time it will be a Christmas miracle.

You should consider swapping pads between track events. One set for street driving and one set for track driving. Swapping pads on your CR is quite easy (guess how I know.... :lol: ) -- jacking up the car and removing/reinstalling the wheels takes longer than the pad swaps.
But, the short of it is that you're not going to find a good track pad that's also quiet on the street. You might find some compromise pads that are okay on the track and not too noisy on the street, but that won't be a long-term solution as you and your wife improve on the track.

Do you know of any decent compromise pads? Even a compromise pad would hopefully last a lot longer than the stock pads and have tolerable fade, given that our sessions are usually less than 35 minutes.
We could do the pad swapping, but we're trying to focus our time and energy on improving/enjoying our driving rather than equipment stuff.
Definitely can't stay with stock pads for the track, since they don't last long and seriously lack bite.

I've run both Porterfields R4S (S=street) and R4. The R4S is a step up from stock for sure and pretty damn good street characteristics (even low dust!). Ran them on the vw, boxster, and some other friends have used on bmws and 996. They wore VERY fast on the Mcoupe at the track - I think they didn't like getting that hot on those little brakes. The R4 is quiet, but dusts like HELL and is hard on rotors. Tracked & DD'd them on the jetta for quite some time.
Hawk makes a compromise pad (HPS?) as does PFC. Just going to have to pick one and see if you like it. Its like picking a beer. Individual (and cars) tastes vary. Try them until you find one you like. Not like they last forever;)

I guess I'm lucky. I've been tracking since 1996 and have never had an issue with brake noise. I've tried pretty much every pad out there.
On my street car, I bought a set of metallic pads and they started making noise from day one. Was driving me nuts. I went to the auto parts store and got a brake caliper lubricant and stopped the noise immediately. It's been 5K miles since I put it on.

I just had a look at Hawk's website and I see that they have a spectrum of pad types and agressiveness.
Racing: http://www.hawkperformance.com/motorsports/applications/gt.php
Performance street: http://www.hawkperformance.com/performance/
Looking at this info, the HT-10s do seem to be towards the aggressive end of the spectrum. And the HPS looks like a potentially good compromise pad, but I'd like to see what Pagid and others have to offer also.

Are the HPS noisy on the street? How's their bite compared to the stock pads you've had?
Paul Weston put me on Kurve Friction as a compromise pad about 11 years ago - but you have a very different car. I'd ask Paul and also Eric (magnetic1) and see if they have one they agree on. Both GREAT guys, and fair. Eric is a BMW guy, but okay anyway.

We actually used the Hawk HPS pads for a while initially. They were a decent compromise pad, and did well at most DE's. But we discovered that braking was too intense for them at Watkins Glen; lots of high speed braking zones. But at other tracks, a set would easily last the entire weekend. Not noisy and not dusty. But the braking level is not as good as a true track pad.

I've run both Hawk HPS and HPplus. I found HPS to be a good/quiet street pad with strong initial bite if you prefer that characterstic for autox. I don't recall ever tracking the HPS.
HPplus were crazy noisy on the street, but stopped well at low temperatures. For me, they were adequate at the track on the 944, but not adequate on the 96 328is. I currenty have PFC 97's on the 944 which are actually a lot quieter on the street than the HPplus, but the dust is hard to live with.

Wow, just one weekend! Sounds like the HPS won't cut it for me, given the number of track days I have in mind. And even at Summit main, we come into Turns 1, 5 and 10 at around 100 or more, so fairly heavy braking there too.

I'm doing both track and autox, but track is my higher priority. If the HP Plus are crazy noisy anyway, I'd probably be better off staying with the HT-10s, since they seem strong enough on the street and great on the track (strong bite, but not hard to modulate). But I'll take a look at the PFC 97 also, since I don't mind dust as much as noise.
Does anyone know whether Pagid has decent compromise pads? Basically, I'm looking for a proper track pad with a tolerable level of squeal - doesn't have to be silent, just tolerable. In other words, a toned down track pad rather than an enhanced street pad.

With 2 drivers in beginner's group you should figure out a set of pads every two events. There are no quiet race pads. There are no street pads that last long on the track unless you drive at street speed.
Hawk HPS at street pads. HPS Plus are advertised as track day pads that can be used to drive to and from track.
Some here will say that they use the Pagid race pads on the street, but I have never been able to leave Pagid race pads on the car and not get the shudder due to pad deposit on the rotor when driven on the street. It is hard enough to bed them for track use.
Select a brand and stick with to develop your braking habits. I see guys change brands every 1-2 years based on what someone else says. Brake pads are like pillow, your results may vary.

If even track pads won't last long, sounds like our best bet might be to keep the current pads (HT-10 front, stock in back) until they're done, then try something else next time and see how it goes.
Does anyone see a problem with brake balance resulting from the different pads front vs back?

Does anyone see a problem with brake balance resulting from the different pads front vs back?YES. This can cause all kinds of problems. One set can come on as the other set overheats and starts to boil off and ablate. You can end up with bias that changes while on track. Please see my avatar for results of improper brake bias.
People also tune braking systems by using different compounds front and rear. To do so with good results people tend to keep both sets in the same working heat range and tune via the torque ratings of the pad compound.
As said in the long run you will find that you will need to have street pads (work great when cold) for the street and track pads (work great when hot) for the track. Anything in the middle will leave you wanting when at ether end. Considering that all the driving is at ether end and you are back to 2 sets of pads. The good news is it is easy to swap pads back and forth once you have the basic tools and simple methods in hand.

Much to learn, and need to do it quickly, given this frequency of tracking (will be at Summit again tomorrow)! We were lucky that someone had spare pads at WG and people helped us install them, otherwise the car would have been undrivable Sunday. And the problem came up suddenly - car passed pre-track tech and track tech on Friday with no problems, then all of a sudden the pad concern came up Saturday morning. :shock: Don't want to get caught unprepared like that again, especially 4+ hours from home.

Thanks for this cautionary input. We did get HT-10s for the rear at WG and will install them, so that we have HT-10s all around. When the fronts wear down, we'll figure out what to install next.
As far as switching pads for street and track, since we need to get tech inspections done anyway, maybe we can have the shop install the track pads and then I can reinstall the street pads once I learn how. When I was younger, I enjoyed working on cars and motorcycles, and it looks like I need to get back into it.

Performance Friction 08s are not that noisy on the street. I like them much better than the 97. Great overall pad. They are More rotor friendly and a very nice linear torque curve.
I was always too lazy to change back and forth between street and track pads. Performance Frictions were not as noisy as Pagid and Hawk when not up to temp. This was on my Carrera. I would not leave them on if the car is daily driver, but they are OK to and from the track. Dust will always be an issue with track pads. Some worse than others.
As far as using the Hawk HPS on the track. They aren't bad if you are a green group driver. If you are past that level, then you will find them lacking. Feel free to PM me if I can be of further assistance.

I was just talking with Sloan at SSI about pads and tires, and he mentioned you as the expert on pads. He'll probably be giving you a call.
If I'm too lazy to swap track and street pads, Sloan agrees that PFs are good pads and much quieter than Hawks, while still good on the track and good enough for the street when cold. Would need to decide exactly which PF to get, if not the 08, but PF is the direction I'm currently leaning. I guess these are the options: http://www.performancefriction.com/Repository/Files/compound_descriptions_20101002.pdf

I am a huge fan of the 08 and the 06. I have gotten lots of positive feedback on the 08s when used on the 997 and 987 platforms. I've raced on the 06s in a Spec Box, the 01s on my former Carrera. The 01s have more initial torque and require a very sensitive foot to keep them out of the ABS or lockup, at least that is my own experience with them. The 06 and 08 are both rotor friendly and work right down to the minimum thickness. I've seen end users run them down to the backing plates, though I don't recommend stretching them that far.

The 911 is 997.2 C2S cab. Pretty little thing, but it will still have to serve track duty.
Sounds like maybe the PFC 08 is the way to go?

Sorry to hijack:
Question for the 951 guys: do they make the 08 or 06 for our cars? I've run the Hawk Blues for a while now, but before that I was on 97's and Porterfield R4's. I would go back to the 97 but hate the brake dust issue -- super corrosive and cement-like when it gets wet.
The 08's or 06's sound like a great alternative!

Took the 911 to Summit main today, and the stock brake pads sucked compared to the Hawk HT-10s we put in the Cayman. I'm fully convinced that stock brake pads don't cut it on the track. Very likely that we'll wind up with PFC 08s in both cars. Will try to use them on the street too, and if that doesn't work, pad swapping will be the way to go.

Thanks Mark! Great to hear. I just checked your website and noticed you have the 83 compound on sale. For about half what the 08 is going for. Is there any merit to considering this? IIRC it's a pretty aggressive pad from a wear standpoint, yes? Might just be cost effective (and 'sanity effective') to go with the 08 anyway.
Looking forward to the 08 -- been a long time coming for the 'fo-fo.

IIRC 83 will cause you to hit you face on the steering wheel the first time you use them after they warm up. They are for the worst of the worst conditions such as Nascar short track.

Don't overthink it -- they are a wear item, and will have a short life if you track the car. Pick a compound and give it a try. You'll need a new set before you know it, and you can try something else at that point if there are elements of the first set you did not like.

As pads wear, the remaining material works less well as a heat sink. A good rule of thumb for track driving has always been that the pad material should be more than the backing plate. As you get closer to that thickness, not only will the pads heat up more and work less, but they'll also wear faster. If say the backing plate thickness is twice the pad material, the 1st half will last much longer than the last half.
And x2 what TR says. We keep some used pads around for backup. Often re-sort thru the used pads and keep the 4 best ones as backup.

I also noticed that with the stock pads, as they became thinner than the backing plate, the edges of the pads started to crumble away. Not a comforting sight! I don't know how track pads compare in this respect.

I've had Hawk HT-10s crumble. Did not have that issue with Pagid Oranges. But the HT-10s only crumble when worn down a bit less then backing plate thickness (they start to overheat).
Please note that all track pads DO NOT behave in exactly the same way. About the only generalization you can make is that track pads will last longer and stop much better at track events then street pads.

I'm sure that for some of you, that is chump change, but I'm currently trying to get rid of parts,not add... :D

I had a single front HT-10 pad crumble at Mid-Ohio and it was almost new. Luckily I had spares. Brake caliper was fine, and new set did well without a caliper rebuild.
One other thing - very hot brake pads will wear your rotors more quickly.

Also, you can swap the inner and outer pad at each wheel to get a little more life out of them. I've alread been through the "what pad" process so have only spares of the ones I use. When I replace a set I simply compare those with my current spares and toss the ones with more wear. I already have enough “spare parts” I haul around with me. Don’t need several sets of "maybe good" anything ok except RA1s cause those suckers are goodest just before the cord shows all the way around the edges and the middle starts to bubble

Kurt summed up the PF83. They will stretch your eyeballs and they require a delicate application of the brake pedal. But man they do haul the car down quick. Down side is that they will wear the rotors faster than the newer compounds from PF, Pagid, Hawk etc. Plus side is that since they are a closeout item, the price can't be beat, and in a race, no one is going to out brake you.

Just to update, we did put PFC08 (front) and PFC06 (rear) in the Cayman and have used them several days on the track.
I'm completely happy with their behavior on the track. Ample bite, relatively easy modulation, no evident fade, and they're not showing much wear so they should last a while.
On the street, sometimes they're quiet, sometimes they squeal a little, and sometimes they squeal a lot. But much quieter overall than than Hawk HT-10s. And their feel on the street is good - maybe a bit too much bite even when cold, but not a big deal. So I think we'll be sticking with these pads for both track and street use (too lazy to swap).
Now I need to upgrade the crappy stock pads in the 997.2 C2S (not even good enough for street use). That car will only see a few track days a year, so the thought is to get pads which are good for the street (better than the stock pads) and 'acceptable' for the track. From Pagid, the best options seem to be:
- Sport pads, http://www.pagidracing.com/sport.html, but not sure these are available for our particular 997
- RS 4-2-1 Black, http://www.pagidracing.com/racecharacteristics.html
From Performance Friction, all of their racing pads seem too aggressive for primarily street use, http://www.performancefriction.com/motorsports/brake-pads/compound-descriptions.aspx. They also have 'aftermarket' pads, but I'm not clear on what compounds are available, http://www.performancefriction.com/aftermarket/aftermarket-brake-pads.aspx.
I haven't ruled out Hawks, and I know that they have some 'compromise' pads, but my preference is Pagid or PF for now.
Any suggestions or experiences?

On a car as heavy and will the kind of power a 997S puts down, an in between pad is going to be a huge comprise, especially now that you are used to the PFCs.

Sounds reasonable, but the thing is that I'm very unsatisfied with the stock street pads for street use, so they need to be upgraded anyway. I'm hoping that an upgraded street pad would suffice for occasional track use, especially since I don't intend to drive the 997 quite as hard as the Cayman (it's more expensive, a cab, want it to be a DD for many years, etc.).

My advice, keep the 997S for street use. Didn't realize it was a cab so I must have missed that in an earlier post. Since you have the Cayman R, no reason really to track the 997 Cab.
Hawk HPS (High Performance Street) pads are nice for street use, but still not really suited for the track.

That's more or less the plan, but hard to have a 911 and never track it. Even if I drive it a tenth slower than the CR, it's still fun, and nice to be able to drive more than one car on the track.
Any thoughts or experience with these pads?
Pagid RS 4-2-1 Black
High Performance compound with low fading characteristics and high cold friction. The RS 4-2-1 is a most comfortable medium friction compound and very easy on the discs (rotors). Very popular for brake up grades or tuning. It is OE on various Super Sports Cars among others Aston Martin, Bugatti, Ferrari, Lamborgini, Lotus or McLaren. Suitable for street and light track use such as track days or driving education.
From the description, they sound like just what I need.

I'm not trying to be stubborn or say that everyone else is wrong. I just find it hard to believe that there isn't a pad out there which is a big improvement over stock pads and sufficient for occasional track use. The Pagid RS 4-2-1 Black or Sport may fit the bill, but I need to find out more about 4-2-1, and no one here has mentioned having used it (I've sent an email to Pagid to ask).
Also, note that I changed my question relative to the thread title. I originally asked about track pads which don't squeal too much for the Cayman, and am satisfied with the PFC08/06 which was recommended. I'm now looking for something different for the 997: upgraded street pads which can handle some track use, and which will presumably squeal less than pure track pads. Maybe I should have started a new thread, but I figured we'd pick up where we left off.
Well, I have to admit I did feel the same way 12 years ago. Then I talked to Paul Weston (Weston Motorsports), got good advice, and was happy for 2 years until I went with a full track pad. Paul used to be a local member, but now lives in Florida. That has been mentioned above. BTW, I used Kurve Friction pads those 2 years.
BUT, you're also driving a Cayman R with full track pads, and then you're going to go out on the track with a significantly lesser pad - you're not going to be happy with the much longer braking distances.

You may be right about that. As I mentioned, if necessary, I'm prepared to run track pads (eg, PFC08) in the 997 full time; their squealing can be substantial, but it's not all the time, so it's bearable. But I'd like to at least give something like the RS 4-2-1 a try.
As far as braking distance, I can get into ABS even with stock pads, so the distance may not be a lot longer. The bigger problem seems to be that a lot more pedal force is required, which makes it harder to modulate the brakes, might get tiring, and reduces confidence. I guess there might also be more concern about overheating the pads, with associated fade, and possibly damaging the rotors?

Caution. Opinion to follow.....
If PF still makes it it think it was "Z" compound. Don't bother, I found this compound to be spendy over regular street pads and compromise in all conditions. YMMV and they might have come up with something else.
The thing is this. What you want from a street compound is close to 0% what you want from a track pad and vice versa. You end up with almost 100% sucks street or track when you try and do both with one compound unless you have gone carbon ceramic and they have their own list of issues.
The pad makers know compromise compounds do nether well enough. Most folks end up understanding this and don't bother with compromise pads and they don't sell well. Plenty of company’s put race inspired words and graphics on boxes but they are street pads unless otherwise noted. Take them to the track installed in a car that has any weight and or HP and prepare to be disappointed.

Opinion - there is a difference between cars. I can run my 944 with compromise pads (HP+ specifically) and while they are not as consistent or confidence inspiring as race pads (PF 97s), they will get me through a DE session without significant issue.
Tried exact same set up in the bmw 328 (HP+, ATE blue), and had to quit after 5 laps due to fade. While there could be other factors, I chalk it up to the extra hp in the 328, with brakes that are not as good.

IIRC, the 997.2 C2S cab weighs around 3500 lbs and puts out 385 hp. So fairly heavy and fairly powerful. I didn't really notice any fade previously with the stock pads, but I'm driving faster and braking harder now.
Checked another source and it says ~3300 lbs. Not sure which is correct.

IIRC, the 997.2 C2S cab weighs around 3500 lbs and puts out 385 hp. So fairly heavy and fairly powerful. I didn't really notice any fade previously with the stock pads, but I'm driving faster and braking harder now.
This is the angle I am working from. The same driver that posts this question about this car also is posting "How do I get more track time?" threads. This = track junkie in the making. This forum is littered with track junkies most of which all made the same list of mistakes as the disease progressed.
Taking it easy on pads while driving on the track is like taking a "free sprinted and willing girl" to dinner and a movie. So close yet so far. ;)
As I said earler I am potsing my opinions.

Then he should sell the cab and cayman and get a GT3...forget the pads, buy a new car, IRFAN! 8-)
If he just wants to exercise the cab then I just simpy don't agree with the other comments. The guy already has a track car, and IMO there is no need to have two track cars to maintain by yourself.

Don't think I can part with either the cab or Cayman, but I may add a GT3 at some point (anyone selling?). When that happens, the cab will retire from track duty, but until then I do want exercise the cab on the track now and then. It's unfortunate about the Pagid Sports, but hopefully there's something else out there which will do the job.

Yeah, these really are 6speedonline questions.
Get whatever pads you want. Once you reach a level similar to PCA Potomac's White Group, you WILL toast a set of street pads in a day of track driving. If it's a one day event, then no big deal. If it's a two day event, you may have to sit out Day Two (but you don't get a refund). You'll figure it out quickly enough.
It's interesting to see a thread about maximizing safety and then seeing another one about using pads that are not really up to the task on the track once your driving is at the point whrere you are 135 mph+ at the end of the main straight. I know I would not want to be on street pads, but that is just me.

I don't know anything about compromise pads....I compromise on nothing. However, I have found that my track pads (PF-97s) are very dirty and create a ton of dust. That dust gets all over the wheels and sides of the car. Any water makes it rust, including to the sides of the car. Hence, if you found a nice compromise pad but it makes similar dust, would that crap bother you on a new 997? It would me. I'd just learn to swap pads for the few occasions I tracked my non-dedicated 997. I'd also invest in some detailing products.
Me? I don't mind pad squeal. It lets the people on the streets know I'm coming. And, I'm coming in a Porsche.

Here's Pagids description on the Sports...
RS 4-2-1 Black
High Performance compound with low fading characteristics and high cold friction. The RS 4-2-1 is a most comfortable medium friction compound and very easy on the discs (rotors). Very popular for brake up grades or tuning. It is OE on various Super Sports Cars among others Aston Martin, Bugatti, Ferrari, Lamborgini, Lotus or McLaren. Suitable for street and light track use such as track days or driving education.
They work fine for me for my application of a couple times a year. I use Hawk Blues in the 944.
BlackTalon
07-30-2012, 10:14 PM
Those are probably fine for someone who does 1-2 events/ year (which is pretty common outside of our world -- PCA Potomac does a lot more events then most groups). With only 1-2 events a year, the driver will likely not be carrying nearly as much momentum into the t-hold braking zones as they could be, and also may not be adept at t-hold braking yet.
But with 30 track das in just the first season, you WILL burn through pads that are not track compounds.
Oh, and forget about driving half-speed into the braking zones in order to save the pads, as that just screws things up for all the cars behind you. It's not fair it you sandbag it out their and mess up everyone elses' runs.

Since you guys are wearing me down (pun intended), let me ask a question closer to my original question: what's a good track pad which has moderate enough bite to be routinely used on the street? The PFC08s are pretty good, but the bite is maybe just slightly too much for the street.

I have run PF97s exclusively on my track car. On the street, to the track, drive thru's, 400 miles to mid Ohio, etc. I have no idea what "too much bite" on the street means.
I have drive peoples track cars with track pads on the street and the pads were like ice. Almost like there was nothing there. It was a. 951 and trying to brake when the pads were cold was frightening.

I've noticed that the friction vs temp relationship varies a good bit among track pads, with some of them maintaining fairly constant friction, and others having a substantial friction increase with temp (sometimes with a drop in friction at very high temps). For example: http://www.pagidracing.com/techinfo.html
1) Track pads are often WORSE than street pads on the street, because they work better hot. That said, you generally don't need as much stopping power on the street if you drive sensibly
2) Yes, go to 6speedonline
3) OPINION: This thread is frustrating, and I realize the last thread I found as frustrating was started by and primarily posted by the very same person :( If you really search back, you'll see several of us making 2 similar mistakes years ago, myself included. Not listening to all the experience contained on this board, and doing silly, potentially less-than-safest things as a result.
4) I think you should go to the track with street pads, and bring an extra set so you can change them out when they're gone after the first day. Oh, wait, you're the guy who refuses to swap out the street pads for the track pads for the one or maybe two events per year, instead insisting on compromising (see VGs post above) the other 361 days!
5) I bet you'll like 6speedonline a lot!
Sorry, Irfan, but I have a rule to read every post on Dorkiphus*, so I have to speak up!!

What the good Dr. K said ..
Most track pads squeal and not better than street pads on the street but still have plenty of bite - just drive appropriately for the conditions and all is well. I use to switch pads many years when I started DE but no longer. My DE car is a 87 911 and I use PFC (83 & 97) and Hawk (Blue & HT10) and they work fine on the street. If I were to track my DD (951), I would switch out the pads. It is one of the simpler things to do on a Porsche - less than 1 hr for all corners. I'm willing to help you if you wish. Lots of good recommendations on this thread ;)

1) The PFC08/06 we have in the Cayman are definitely better (more bite) on the street than the stock pads were. As I noted, the cold behavior of track pads depends on the pad.
2) Will ask at 6speedonline.
3) I did take the advice given regarding the pads for the Cayman, and I've taken lots of other advice too. But I've also found that advice given is often conflicting, even when it comes from very experienced people. Whether to use R-compounds at this stage (Blue+) is a perfect example. So it often becomes necessary to probe more deeply before making a decision.
4) I've already experienced the rapid disappearance of stock pads in the Cayman at WG. The 'street pads' I'm considering for 997 now would need to be a big upgrade over those. Call them 'compromise pads' or 'moderate track pads' if you'd like. The Pagid 4-2-1 (classified as a 'race pad') might have been what I'm looking for, but they don't make it for the 997.2.
5) I've found 6speedonline useful in the past.
I don't mind your speaking up. That's why I'm asking for advice. And I was cautioned before joining Dorki that people don't pull any punches here, so you have to have a thick skin. :)

When you install Pagid race pads on top of a layer of an incompatible pad material, bedding might take much longer or in worst case won't work at all. It can also result in sub-optimal brake performance.

On the topic of cold vs hot bite/friction with track pads, note in this graph how the RS 4-2-1 and RS 14 have very little variation with temp:
http://www.pagidracing.com/techinfo.html
Since the 4-2-1 isn't available for the 997.2, the Pagid rep recommended the 14 for my application. Though he didn't say so, the friction curve may be a key reason.
CORRECTION: Zooming in on the graph, I noticed it's the RS 5 (Blue) which has the fairly flat friction curve. RS 14 isn't flat, and probably not good for street use. Anyone have experience with the RS 5 Blue?

Believe whatever you like. Buy whatever you believe to be the correct pads. Run them for a couple events, and then you can make a longer-term decision based on you first-hand experience.
Not sure where the 'drink the kool-aid' came from here, but I can tell you most people giving the advice here have well over 100 track days, and 1) had a time when they were at the same decision-making point you are currently at, and 2) have witnessed hundreds of other drivers be at that same point as well.

Now there is a data point where I do have some first-hand! Keep in mind what you describe and my moonwalk in T1 were not the same thing. I was not switching from one formulation to another I installed new dead flat pads on old slightly dished rotors. New pads had little contact with the not flat rotors and the rear pads were still hot and grippy from the last run which was almost back to back. I was on point the next lap after coming in for the hand slap at black flag and finished the run within some laps that were inside one second of my best time. (All that aside I was simply too hot for the car condition coming into T1);)
Talking to the wall, read at your own risk. Keep in mind most if not all cold formulation pads are not transfer pads. YMMV but I have found that slapping in and bedding track pads after pulling a set of street formulation pads to take no more than the drive to the track or less. Slap them in the night before, drive to track have at it no muss no fuss. YMMV.
Street pads are formulated to work cold, not make noise when cold, not make harsh dust that eats rims, paint and be kind to rotors. Track pads are formulated to work hot. Some work OK on the street. I use PF-97 in my 912 but it is also a now and then car not a day to day car. I also don't care if it sounds like I am killing hogs from time to time as the open J pipe wins. The rims are ratty track grade with an existing hard rust like layer of dust that sticks to the rims. Almost any pad will work with a 90HP 2150 pound car. The compromise pads I used for a while proved to be the most expensive as they were 2 sets a year and the FP-97 were 3 years per set. Don’t expect this from 3000+ pound 350+HP cars.
"Trust but verfy" is spot on. Trust me the street and track pad swap back and forth advice as been verified by many track experienced people. Slap them in between sessions and try and do a best time second lap? No one is recommending this.

Most on this Dorki Board could have swapped your street/sport pads for race pads and back to street before reading through all this, a bit of abrasion on each rotor whilts you are changing should keep any build up down and only take a second!!!

I sorta agree with Stephen about the lower end of the graph. The "cold" performance doesn't make total sense. A number of the pads shown appear to be almost "inopperative" at low temps, but I know that's not the case. As Stephen mentions, the axis appears to be somehow warped; even one of the comments on the board thread mentions it.

According to the graph, they don't work at all below 120 F. I've driven the DTC-60's on the street in the winter time, in DC traffic, and didn't have any trouble. They worked fine. Did they feel exactly the same as street pads? No. But I pushed the pedal and the car slowed down, and it was responsive enough to be comfortable in urban traffic.
"Work fine" is indeed subjective. Suggest you buy a few different sets of pads. Try them for yourself and form your own conclusions.

OK, I see what you guys are saying about the lower end of the graph. I myself have driven the HT-10s on the street and there's no way the friction coefficient dropped to zero at cold temps. I don't know where the graph is wrong, but I'm willing to tentatively assume that the Hawks have a significant drop in friction at low and high temps (ie, correct shape of the curves). And we've read reports in this thread about some track pads having very little friction at cold temps. By comparison, the friction curves for the Pagids are much flatter, at least over the temp range shown. I'd like to get my hands on the friction curves for PF.

Given that some track pads are adequate for street use, and that I don't like the stock pads in the 997 for street use anyway, using 'mild' track pads full-time in the 997 is the direction I'm currently leaning.

I talked with the Performance Friction rep at length about this. They have aftermarket Z-rated carbon metallic pads which are good for the street and a big upgrade over stock pads, and they also consider them good enough for relatively short track day sessions, as we typically have in DEs (but not sustained racing). They're apparently not subject to a lot of fade at high temps, but they may wear faster at high temps, so it's important to keep an eye on them. Unless someone here tells me they've tried them and found them inadequate for occassional DEs, I'm tempted to give them a shot.

PF Z Rated street pads are nice for that application. Just like Hawk HPS, a great street pad. Like any other street pad, you are going to find them lacking when heated up on the track. They might be OK in green group, but as you progress, you'll wear them out quickly.
I traveled this road 14 years ago when my daily driver was also my DE and autocross car. I tried a compromise pad and ended up with track pads on the car 24/7.

Page 16?! Holy cow -- haven't been paying any attention to this thread; would've thought everything would have been decided by now. And I thought I was indecisive on things like this. :)
In regards to the "spending time swapping brake pads" comments: is spending 2hrs/mo "working" on your car too much time?
Now, I know you have two very nice (and NEW!) cars that I'm sure are in great shape (that wasn't sarcasm, BTW). But DE's put a HUGE amount of additional wear-and-tear on our cars. When doing DE's, you can't be retroactive in solving problems on these cars. Now, my car is much older than yours so admittedly I'm sure I need to spend considerably more time under my car that you might. That said, I see swapping brake pads, bleeding brakes, and doing oil changes as a way to get reacquainted with my car's potential flaws.
I'm sure many of us here have uncovered a problem with their car whilst performing a mundane task such as swapping pads.
Or, show of hands: how many people have uncovered something stupid a mechanic may have done while working on our cars (doesn't have to be a track car)? What happens if you take your car in to get an alignment and the mechanic forgets to tighten a bolt? Hopefully, the tech inspection will uncover this, but still....
My point is: you can't realistically think you'll be able to do a million DE's without needing to get underneath your car and understand (at least on a high level) what's going on... that is to say, unless you're GT3's girlfriend. In which case you can.

What about for Blue/White group? I talked with Sloan about it, and he thought they might be worth trying for my application. If they don't last, I can move to track pads 24/7. Or coming at it from the other side, what's the 'mildest' good track pad you've run across?

Irfan,
Here's my advice. Get 2 front sets of the HPS or PF-Z's, and give them a try at the track. Compared to the full on track pads, they are considerably less expensive. Worst case scenario, the pads don't hold up well throughout the weekend, and you have a 2nd set on hand to get you through the last day. If you don't like them and you haven't gotten into your 2nd set, you purchase full on track pads for the next event, and use the 2nd set as your street pads.
FWIW, when tracking a car, its a very good practice to bleed your calipers before each track weekend. The fluid in the calipers is what's abused the most, and flushing it out helps avoid a mushy brake pedal. While the wheels are off, easy time to change the pads, too. At the end of the track weekend, there's plenty of folks that could loan you a floor jack so that you can change to street pads for the ride home.

Given that some track pads are adequate for street use, and that I don't like the stock pads in the 997 for street use anyway, using 'mild' track pads full-time in the 997 is the direction I'm currently leaning. Not currently interested in spending ~2 hours swapping pads for one track day, and I can live with some squealing on the street. Others may have different priorities.PF-97 can take heat OK but still has OK torque cold but you will have to be care full of the dust as it binds to stuff after it gets wet.
I talked with the Performance Friction rep at length about this. They have aftermarket Z-rated carbon metallic pads which are good for the street and a big upgrade over stock pads, and they also consider them good enough for relatively short track day sessions, as we typically have in DEs (but not sustained racing). They're apparently not subject to a lot of fade at high temps, but they may wear faster at high temps, so it's important to keep an eye on them. Unless someone here tells me they've tried them and found them inadequate for occassional DEs, I'm tempted to give them a shot. A bit more info here: http://www.performancefriction.com/aftermarket/aftermarket-brake-pads.aspxI used Z rated pads and noted this earler in this thread. I was unhappy with them in a 90HP 2140 pound car in green and blue run groups. Just an opinion here.... If I can over drive them in my litle green car you will roast them in a 997. If this is not enough and I suspect it is just that, not enough, read the next quote down. He is not selling coolaid.
Most racers see more track time in a DE than a race weekend.
Irfan:
PF Z Rated street pads are nice for that application. Just like Hawk HPS, a great street pad. Like any other street pad, you are going to find them lacking when heated up on the track. They might be OK in green group, but as you progress, you'll wear them out quickly.

What is the fun in having to drive gently just to preserve wrong formulation pads? Try the Z rated and see for yourself. Please report back so others have a nother data point. Or Go with a PF-97 type compound and be good at washing the wheels.

Thanks for reminding me about your experience with the Z-rated. That's strong evidence that they won't do the job for me. As Tony suggested, maybe I could try them for one track day and if they don't cut it, use them as street pads and then switch to track pads for the next track day. I'm resisting it (just want to drove), but you guys may well get me changing the pads myself sooner rather than later. :lol:
The PF guy seemed to really prefer the 08 over the 97, apparently because it's a new formulation and they consider it to be better overall.

D00d you are going to have to show me the 50 foot tine shot. My boy would love that trick. :) His latest is to take 50 cap gun caps and bundle them in a wad of paper then mash the wad with a brick. :roll:

Avoid PF 97s. The iron oxide is a horror with whatever it touches if it gets wet. Hawk HT10 uses brass as the binder and cleans off easily without damage. Don't be the guy that attends a DE (drivers EDUCATION) and then won't drive on the skidpad or in the rain because his pads will become demonic if they get wet.
I am glad to see the logic of track pads is sinking in. FWIW when I 1st got my 911 I had about 200 track days in other cars but wanted to learn the weird dynamics of a 911 on 11 year old street tires. I figured a sport pad would suffice in my 200 hp 2800 lb car on Flintsone tires. I was wrong. They were vaporized to the backing plates in about 6 sessions while I thought I was pussy footing it.

What ever you do, don't get PF 97s if your married to a chick with concourse tendancies......
Although it seemed that waxing the wheels before the event helped keep from ruining them more.

Not a concourse chick, but the PF97 are out. See, I told you guys that you don't always agree. ;)

You already answered your own question earlier when you said you like the PF08 on your Cayman R. You will like them on the 997S as well.

maybe it would be better if instead of switching pads you just switched the cars instead?
goin to the store? use the street car that has street pads.
goin to the track? take the track car that has track pads.
so easy even a dorki can do it
Worst case scenario, the pads don't stop the heavy, powerful car well enough and you go sliding off the track (but hopefully you'd learn this in turn 1 at Summit Main and just get stuck in the gravel)
FTFY... :p

Not yet, but getting close.
One thing I should have mentioned earlier is that I've done two track days with the 997 using the stock pads and they held up fine. Lack of bite compared to race pads, but they did slow the car as needed without obvious fade. I wasn't as fast then as now, but not slow either. That's what got me thinking that Z-rated might do the job.
But OTOH, WG chewed through the stock pads in the Cayman quickly, indicating that something significantly better than stock pads is needed for the track (especially if Red instructors drive the car :shock:). Not sure yet whether I'll try the Z-rated or just go straight to the full race pads.

By all means try the Z pads. How else will you know or not?

As I may have mentioned before, WG is tough on brake pads. We experienced the same problem on our first visit. Both the Boxster and 944S2 ate up Hawk HPS brake pads. But, figured out this was because of 5 braking zones from 100+ mph. No other track comes close. Prior to WG, Hawk HPS easily lasted the entire weekend.

no way. z-rated are the best. ions of friction more than hps, ceramics and even the new mylar pads. best duel purpose set bar none. just ask all the drovers
