My mate does run 330mm Ap's on his 3 door and it seems to eat brakes on any track day, no idea why as I've been told its very unusual but I know it pisses him off as there £350 for a set of rotors which makes track days damn expensive .
Any ideas what could cause them to warp so quick ? and before anyone asks yes he does do a steady warm up lap and cool down lap.
He is probably using Performance Friction carbon metallic pads - you can't beat them for stopping power, but they eat discs for breakfast, lunch and dinner

. I had the same problem, I went through THREE sets of rear discs to one set of PF pads (and even THEN they were only half worn

). When I fitted the current new discs, I binned the PF pads and fitted DS3000s - no more disc wear

.
Mike- Its Alpina and he runs Ap discs from you and DS3000's
Just real unlucky I guess
