Вот еще один интересный коммент:
All the PCCB rotors, and in addition the rotors for Ferrari, Bentley, Audi, Aston Martin are manufactured by SGL Carbon in Germany. The rotors in all these cases feature a laminated friction surface that is bonded to the body of the rotor. This friction surface is only around 1.00mm thick, and with prolonged track use it starts to de-laminated from the body of the disc. I've sent detailed images of my rotors to SGL Carbon and they've stated that the wear I have is not unusual for the mileage on track I've done - they even commented the rotors were not designed for the track!
