and replacement costs won't be much less!according to the Dutch pricelist, they are only available as an option on the Quadrifoglio, for a price of Euro 7.500,- .......
100% this. I had them on a GT3 and I found that track use killed the disk. The expansion\contraction quickly cracked the discs and I got through about the same number of PCCB's over a given set of track days as I would standard discs and pads. I only used to run the pads to about halfway as otherwise you can generate more heat on track and exacerbate this disk problem, so the whole thing was a fairly expensive endeavour as I was doing about a track day a month at the time.and replacement costs won't be much less!
When they were first fitted as std to Porsche GT2, the trend was to remove them and fit normal brakes, keeping the PCCB set to refit when the car was sold, the next owner would then do the same!
Replacement discs were about £10,000, they didn't last forever and there were disc failures.
Life of a set of PCCB discs on track was about twice that of std, so costs considerably higher.
In normal road use wear was extremely low.
So great for road, but very high replacement costs if you track the car.
