About 2-3 months ago, I created a thread asking opinions for track day brake upgrades. It was between AP, PFC, and the Surface Transforms.
I went with the ST's primarily for the low-brake dust and just like the characteristics of any CCB's for that matter. The rotors were purchased used and it has been resurfaced one time; the pad of choice is Pagid RSL1's as I heard it brings a very controllable bite as well as modulation.
Reasons why I didn't choose the AP's or the PFC's. The AP's are probably the best choice for running cost/simplicity when changing pads/performance. However, I never thought of the OEM calipers on these cars are lacking in anyways; sure the AP definitely is a step up but I still chose the CCB's over AP. I haven't had a chance to try out the PFC's in person so I can't really judge how much better it is over the AP system, but it definitely was the most "motorsport" looking system of the three. If I were to get a steel brake system, PFC would be my choice.
I will keep this thread updated on the performance as well as the longevity of the ST + RSL1 setup once I get a chance to hit the track.
I’d be interested in what service length looks like before these need resurfacing. I have a 2916 GT3 with around 60 track days in the original PCCB rotors. Third set of pads. Prior owner is a very quick driver, he put most of those days on the car (I’ve had it since September).
Car passed CPO but I don’t have the carbon readings, rotors are still visually fine and functional. I’m honestly blown away there are that robust. I’m curious how the STs compare.

finally we might have someone actually able to carry out a real experiment to determine the track days lifetime of CCB rotors (albeit ST and not PCCB) ... 60 days is pretty good!

Depends on the track... 60 is a lot, must be minimal high speed braking zones. 2-40 is the norm. As per ST, still going strong, lighter, and run cooler... ST fan boy admitted.

Those 60 days were at Pacific, the Ridge, ORP, PIR and a few other places. The car was owned by the current local PCA chief instructor, he’s damn quick and a terrific driver. Plenty of 150 mph down to 60 ish braking zones, or 120 down to 40.

2... 2 ... 2.... that I just do not believe unless they were installed on the U.S.S Enterprise (1701) and used to drop out of warp ...
Just somewhat finished the bedding in the procedure, honestly speaking... this combination gave me the best modulation control of any brake setups I have experienced on a GT3 platform. The linear progressive bite allows you to have total control over how much you want to slow down for; initial bite, medium force, threshold braking... you name it...
I have had Girodisc paired with Ferodo 1.11's and 3.12's as well as OEM PCCB with Pagid RSC1's. I can't really comment on how the bite feels compared with Girodisc's since I haven't had a chance to go on track yet, but will definitely update on this thread once I have more experience with the setup.
As for comparisons with AP, I have not had a chance to drive a GT3 with AP's though I have had driven a C7 Z06 with the AP's on the track... and I gotta say, the modulation/pedal firmness of the ST's is truly on point with the AP... but this is on the street... so I'm going to hold off on that until I get some seat time on track.

My car was CPOed before i purchased as well. I know that the previous owner of my car tracked it but unknown on how much or how hard it was tracked.
from an oldtimer i meet at PITTrace he said the secret to keeping the PCCB rotors in good shape is replacing the brake pads a 2/3rd their life. so i have been following that rule and im happy so far

i do plan to go with Surface Transform when replacement is needed. i like that they can be refurbished. that is attractive to me with significant cost savings
