PCCB

There was a post not so long ago (although it might have been on another forum) that suggested PTV will quickly knacker them if you're into tracking the car.
The mere fact that people who are into track days often remove them in favour of steel discs confirms, at least to me, their unsuitability in that domain.

Apart from that one post about rapid wear on the rears discs, they seem to be excellent and I wish I had them on my car...[]
Usual grinding when cold and squeal still seems to be a common report...

Thankfully Gary I have them on mine. No sign of any wear at all and that's with 63k on the clock. The pads are about 1/3 worn.
No squealing and no dirty wheels are a real bonus too.
If they were that bad for track days then why do race cars have them fitted. Perhaps it's more to do with the expense of replacing them if they get damaged or maybe people like to change to different pads that are not available on PCCB
I've had 3 Porsches with PCCB - a Gen 2 C2S, a 997 GT3 and now a 997 GT2. It's all a matter of personal opinion, but I wouldn't be without PCCBs, I find the brake feel to be superb at all times and haven't had any problems with longevity. I did the most track days with the GT3 (19 in the 15 months I owned it) and the discs were still in excellent condition when I sold it. I am careful about always doing a cool-down lap and on track days turn off as much stability/traction control as the car will let me as I believe those systems can use the brakes, especially the rears, for significant amounts of time without it being obvious to the driver.
You do have to be aware that the discs will not tolerate as much impact as the steels, especially on the edges, so it pays to be careful when removing/replacing the wheels!

The latest PCCBs (ie since Gen 3, c.2006) are widely fitted to lots of Porsches - some as an option, some as standard, and I've not come across any significant negatives.
Those who have them seem to love them, and the associated benefits.
But, brakes are a consumable, and some people who do a lot of track work might go for more cost effective alternatives such as alcons or similar, although the Carrera Supercup race cars use PCCBs..

Thanks
All pretty positive feedback really
Early wear therefore seems rare, a fact also confirmed by the test track at Silverstone who say PCCB last well and they are used on track everyday. occasionally they have the inner rear going but thats because its a RH circuit and the track is too short to let the discs cool down.
