The info I've found is
"Measure with a precision micrometer. New thickness is 34mm for front, with minimum 33.5mm.
Rear new 28mm and minimum 27.5mm"

PCCB rotor life is determined by more than thickness alone. Porsche dealers use an electronic tool to measure the carbon content of the rotor to estimate remaining life. Some people believe that dealer estimates are overly conservative and that they will recommend replacement of the rotors prematurely.

Couldn't agree more! My friend had a 2009 Turbo with steel brakes and the ride was significantly different. I won't buy another car without PCCB and if it's the right car but no PCCB, it will be my first mod.
