Nevertheless, I agree that the 368 mm rotor is sufficient in terms of thermal capacity for the e9x M3. I'm running the PFC BBK with a 372 mm rotor and I've never encountered any type of brake issue. If PFC offered a larger rotor I would still use the 372 mm rotor.
just found this on Stillen website. Its called Formula Brake Kit. The front rotor size is 15'', different from AP7100 kit 14.5''
