Man, thanks for posting that. I really appreciate it. We optioned PCCBs on our Cayenne without a test-drive (the car wasn't out yet). Gambled and won, at least so far. I'll make a point to see if I can drive an F90 with CCBs before making a decision. Porsche is known for incredible brakes. BMW, not so much. Standard steel / cast iron may be the smart choice on this car.
