Gen III PCCBs are great on track.

Nothing like the Gen II PCCBs, which it seems like nearly everyone on RL uses as the fulcrum for the meme "PCCBs are not suitable for the track"

Can you quantify "great"? I've heard people suggest that they are better, but I wasn't able to find much to back that up or what it means.

I believe that Porsche markets PCCBs based on the lighter weight vs. steel brakes and the relatively fade-free performance under heavy braking. I don’t think they make any claims about longevity or wear.

A well-worn topic, no doubt. I always find it ironic that PCCB technology, bred for racing, is often chosen mostly because they don't produce much dust and don't wear out easily in street driving, yet when it comes to heavy track use, people get iron rotor cars or do an iron rotor conversion. Now that my iron rotor car has some miles on it, including track miles, but finding I do fewer track days than I anticipated, I'm weighing the same choice: go with replacement irons or convert to CCBs. The choice is a lot easier if the price points converged more. Has anyone tried this conversion? https://www.autoquestcars.com/custom-11

Anecdotally, I know several owners of 991.1 GT3/RS who have over 4K track miles with good to moderate density readings on all four corners.

I kmow one GT3 owner who is on his second engine but his original OEM ceramic rotors. Around 6k total track miles at last count

Nad, that beautiful C4s w X-51 in sapphire blue and sport techno wheels in body color would not be the same w/o the yellow binders! Bite the bullet and replace them, then track only the GT3! Your 991.1 is the prettiest car I’ve ever seen! Keep it a long time and in the oem condition you bought it.

That's interesting, because all the .1 GT3 owners I know that track either didn't spec PCCBs or switched out their PCCBs before tracking. Are they the same from the .1 to the .2? I specced PCCBs for my .2 GT3, but I don't plan to track it.

I got PCCB because I have no plans to track my car. My SA told me that if I don't track my car I'll get 100K km no problem. That's what I wanted along with no brake dust and lower unsprung weight. To my knowledge the material of the rotors are the same in the .1 and .2. However the .2 rotors are larger. Same size as the turbo S. I believe mine are 380 and the .2 are 410. Had I planned to track the car I would have ordered steel. Even formula 1 cars go through their brakes and they are full carbon. I am not sure the OP has realistic expectations. I also agree that "noobs" are not smooth on the track and therefore harder on brakes.

PCCBs on the 991.1 were 350mm, front and rear. The PCCBs on the 991.2 are much larger at 410mm front and 390mm rear. They are really large in comparison to the standard “S” rotors for the 991.2.

I had PCCBs on both my 991.1S and my 991.2GTS and love them. Like you, I don’t track my car, though, and hope to get long use out of them.

I believe the 1.1 and 1.2 GT3s have the same Gen III PCCBs (size and materials).

I believe the Gen III PCCBs are also on the 991.1 TTS, from what I’ve read on these boards.

I am still planning on spec'ing PCCBs on my incoming Carrera T, but am a little nervous about it. Only because I just did a Porsche Experience day and of the 5 cars I ran on the track (all with PCCBs) the Turbo squeaked horribly. I am chalking that up to a very odd usage pattern being a PE car, but it did give me pause.

The only other option would be to go 3rd party after purchase and that would basically be similar money and no warranty.
