PCCB's on the track, to me, would just embody the "pay to play" mentality. I prefer my PCCB's over steels any day. In fact, it's a deal breaker if a car doesn't have ceramics now for me lol.
To LoloM, it almost looks like your pads were braking apart, then that material getting caught on it's way out of the pad which led to scoring the rotor. I'd be asking for a warranty claim. Warranty doesn't cover components that typically wear, but you have a clear difference there one side to another.
Thanks for sharing - shame they went with an F type R which has massive brake fade problems after 1 hot lap.
True. Would be interesting to see the comparison on something like a GT4 where the iron rotors are already quite adequate on track for the car (same as on the heavier and faster GT3 and RS).
Here is a picture of the pads :
Pads of scored disc
Pads of "safe" disc
Weird holes on the damaged disc pads. Do you guys think a default in the pad could be the reason for the scored disc ?
Thanks
it's been over a year since your post...any update on wear/scoring?
i have a few track days on my car and have never been off-course...when picking up the car for oil change the service advisor directs me to the rotors and shows me scoring...not too diffferent than your rotors.....he says he'will order new bolts so he can remove calipers to investigate further....does this sound right?
can someone direct me to the "best" forum thread on PCCB's vs. Steels for longevity - how long do PCCB"s actually last for heavy track use....for myself I just can't see having $20,000 consumables on the car…correct me if I'm wrong but OEM porsche rotors are $9500 for a set of 2?
for me it just can't be worth $10,000/Axel vs. steels
I've order my car with PCCB'S and will lovingly bubble wrap them for the next owner…after I'm done flogging the car with steels on it…

If I had PCCB's on my car, I'd seriously consider the Surface Transforms rotors - less expensive than PCCB, longer lasting, and can be refurbished. Having to use 410/390 and thicker iron rotors seems a little unnecessarily heavy...
In fact, I might consider the ST's with Red Calipers and their spacer kit (but then limits ability to use 19" wheels)
Had a 991.1 15 GT3 I tracked at Sebring. Red group (hero lap 2:19.xx) My PCCB showed noticeable wear after about 5 track days! Pulled them and switched to ST ceramics. The PCCB's still worked great but I got nervous. Put them back on when I traded my car in.
The ST's lasted about 1 yr (maybe 8-10 track days) and now need resurfacing.
My experience only and yrmv.
My .2 GT3 is ordered with iron rotors and I'll put the resurfaced ST ceramics on at delivery.

By noticeable wear, do you mean the striations as per the rotors above? Does that mean lesser life for the rotor? If so, then the higher cost/longer life proposition for the pccb really change for me. For what it's worth, When I run my fingers over my striations I don't feel any difference from the rest of the rotor face, no grove for example....

I had one front rotor with one striation. Probably caused by stone. However, there were a few areas where the rotor wasn't smooth and seemed like it was close to delaminating. I had the early gen pccb on a 996 GT3 and those grossly delaminated.
When this newest pccb for the 991.1 GT3 came out, there were threads stating a 918 had over a few thousand miles on original PCCB's at the ring and I was hopeful these new rotors would last a long time. I'm sure these new rotors are better than previous gen but they will not last long on a track like Sebring with multiple full hard braking zones.
I did like like the feel of the PCCB's better than the ST ceramics though. Better modulation. Braking power equivocal. Will try different pads when I put them on the .2.

Thx, I guess I'll find out what they say next week when I bring it in...the service manager says it might be caused by grit/ sand in the pad, also suggested a steel option....I hope it isn't an upsell plan!
My 991.2 GT3 is already on a vessel and it was ordered with PCCB from day one. It was never a question. I just took delivery of my 2018 GTS cab,and that car has steel brakes. On the ultra-high performance models, I always go with ceramics. I want those cars to be at their very best as engineered by their companies. Porsche themselves in the GT3 brochures states that PCCB offers "shorter stopping distances", in addition to better ride and suspension management due to lower unsprung weight. On a GT3 or GT2, I would give up leather interior and PTS before I give up PCCB.
