Here's my latest input: Approaching 100,000 miles and still on original front and rear pads. Rotors still look great. The small round tell-tales on the PCCB rotors are still not readily visible on my rotors.
My former prediction of 200,000 miles is more like 250,000 now. If you keep a car, and you refrain from driving it stupidly, then the PCCBs will last an extremely long time. There was a guy on the 997 Turbo forum who managed to destroy both this PCCB rotors and the calipers in no time on the track--but I don't think he knew how to drive. (The calipers had literally baked to a rust color from the yellow from massive overheating).
Whenever we get around to our next Porsche (probably a Panamera of some type) we will be getting PCCBs again. Like Para82 states--once you go PCCB you never go back. There is significant engineering behind the PCCBs and that should not be regarded lightly. The payoff is in improved performance, virtually no dust and resultant contamination of the wheels and wheel wells, and vastly better handling and less maintenance requirements. Of course, when the day comes that you have to buy new rotors you can only hope that (1) you have already sold the car or (2) the price of PCCB rotors will be coming down as more and more Porsche drivers switch to what is an excellent brake system and manufacturing processes improve.

That depends on how many sets of quality steel rotors you have to replace in the same ~200k miles PCCB will last? It's been my experience over the last 40+ years that I have needed new rotors on most performance cars at 40k miles or so; about five sets per 200k miles. So there is not that much of a difference in cost if you are a street only driver.

Measured the rotors using a micrometer at 3 separate areas vertically aligned and repeated at 120 & 240 degrees for a total of 9 data points. Rotors seem to be at factory thicknesses.
