Forgot to say that I've been doing a lot of track day driving with my GT3 CS MY04. You have probably seen that I have the PCCBs. These brakes are superb with no problems at all after appr. 15 track days with a lot of hard driving/braking. The discs are 100% and the pads are fine. Though, I'll gonna change the pads pro activly for the next season. I reallly recommend the PCCBs.
