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.

Has anyone seen a chart that compares the spectrum of race pad specs all in one place? Please post a link if you know of such a thing.

Compares with respect to which attributes?

All of them of course.

Collin:
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/m...criptions.aspx. They also have 'aftermarket' pads, but I'm not clear on what compounds are available, http://www.performancefriction.com/a...rake-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?

You are in luck as this thread covered just this kind of thing. http://dorkiphus.net/porsche/showthread.php?t=28168

If the 997S will only be seeing a few track days a year, I'd get some PF08s for those days, and put the street pads back in for street driving.

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.

I bet Vicegrip would even be kind enough to teach you how to change out the pads. Once you get familiar with doing it, you can do all four corners in less than an hour.

Me thinks he doth steal an idea or two from the land of RL. ;)
