ID these calipers please!!

[Charlie Stylianos]

uhhhhh...... Please tell me what these are, I'll pee my pants if they are what I think they are.

[Lucky]

They are 930 brakes. Were you hoping for 917?

[thomschoon]

930, the picture looks like the one posted at www.autozone.com where you can order them rebuilt and with the core charge they are still only around $145 each. Only problem is that I tried ordering them a few times and they were never able to get them it, but I havent lost hope. :)

[jpinkert]

Yep, 930 brakes. So what gives? Do you have a source for them? I'm still in need of a brake upgrade for my '72. I've been holding out to see what DinFtown comes up with for 15" fuchs...

[87turbolook911]

Yep...they be 930 calipers...

[}{arlequin]

:D :D

Is it possible that they are knock-offs, made the "same way" but using some cheap ass metallurgy more common in lawn furniture?

Josh, have you absolutely, positively ruled out Carreras on the front? Have you tried it and found insufficient?

There has been the concept of using BMW's 320 4 piston calipers on the front due to the pad increase AND ability to mount them on 3" ears. Anyone know how thick of a rotor those calipers accept? 'Teener guys, anyone...anyone?

[jpinkert]

I haven't ruled out carrera calipers. There are two things I'm looking for in an upgrade:

1) Increased thermal capacity on the ROTOR
2) Stiffer caliper (the aluminum S calipers are spongy)

The carrera/boxster calipers take care of #2, but according to Bill V, don't offer much more thermal capacity. The 930 rotor is 32mm wide and seems to be the universal fix. The carrera rotor is 24mm. I believe my stock rotors are 20mm (mine are 18mm now -- time to be replaced).

I've never run out of brakes at the track. I'm just planning for future upgrades to the car as I don't want to go through this more than once. A hot 2.7 or a warmed over 3.6 is in the cards (still undecided if I want a high revving screamer or a torquey, bulletproof motor).

The conversion w/specs is covered very well on Pelicanparts.com under the teener tech article part.

Looks like we're in the same boat. Seems like unless you go "the beemer way" it's still necessary to get the 3.5" ears (which I don't have yet.) Compared to the cost of a 930 system, it seems like it's worth to give the Carrera setup a try. (I'd rather spend $350 than $3500)

david,
thanks for the direction to the 914 pp article. It's thorough but still doesn't answer the question of whether the caliper will accept the 24mm Carrera rotor. They only talk about the 911 rotor, meaning 20mm. Since I already have the 20mm, unless the 320 caliper accepts something thicker, for most of the 911 crowd it's not really an upgrade. You just gain clamping force, but not any more thermal capacity.

Does anyone know whether the 930 calipers accept a "standard" pad or are they Porsche specific like the M pads?

I guess I missed the rotor thickness question. I thought you were looking for the slightly larger pads from the BMW as a stop gap to the 3” ear issue. To my knowledge no stock ’65 to ’89 911 caliper fits the 930 rotors except the 930 calipers.

What other manufacture/application uses the “M” pads :?:

[Charlie Stylianos]

Thom,

You are correct. I found them on the advanceautoparts site and thought it was too good to be true.

I'm sure others have tired getting them through Avdance auto, and at that price, it almost worth the risk. But if they are not stocking them anyomer, then its no point.

[}{arlequin]

I'm not sure whether any other manufacturer uses the M pad or even the caliper, but it got me thinking b/c I did a little digging to find out prices for pads. Findings are quite disturbing.

Some calipers seem to use a "standard" type of pad, meaning that Stoptech, Brembo, AP etc. design their calipers to accept a certain type of pad. That pad is going to be the same across the range and fit several different kits/calipers. This keeps the price of the pads down b/c they are widely available and each pad company makes them b/c they know that there are many applications for them.

Anyway, back to the point: a set of PFC 97's for one axle for an M caliper costs approx $120-$127. A set of PFC 97's for one axle for a Wilwood Dynalite caliper, costs approx $55!!! WTF? A Dynalite pad is a very common application. So much in fact, that I'm certain each manufacturer has a Dynalite pad in their hi perf line up. This pad is approx the size of a Carrera front pad. So it's basically twice as big as the M pad, but the M pad costs TWICE AS MUCH. Why? Even more pad material was used to make the Dynalite pad. "Porsche tax" strikes again.

So I'm wondering whether the 930 pads are a "standard" type of pad or is it a Porsche-only item which you can be sure will cost double of any other, larger, Brembo-shaped pad?

[cmartin]

That's the Porsche tax. If we are willing to pay $120, why would they lower the price? I wonder what track pads for my civic cost? :)

[}{arlequin]

that's shite... that's not a tax, that's sodomy (BOHICA)... or a robbery at best :?

[Trak Ratt]

Woouldn't there need to be a high performace Honndaaaa before there was a pad :twisted:

[William Miller]

Was it Autozone or Advance Auto that was advertizing that they now offer salvage parts? Anyone check it out?

[}{arlequin]

Yep...they be 930 calipers...
So Vu, how much does an axle set of track pads cost you?

[jpinkert]

I don't remember the cost of PF97 pads for the 930, but I remember being surprised that it was le$$ than the cost of a set of pads for my '72 with S calipers (I have the 3.5" spacing already). The kicker with a 930 conversion kit is the rotors. They seem to be mucho $$.
