Anyone else notice that the front brake rotor diameters for the 330 and the M3 are the same? I've been hunting for the M3's brake diameters for a while now, for winter wheel issues, and i found that the fronts are 12.8" and the rear is 12.9". Then, i decided to check the 330's sizes because of BMW claiming they had to use 17" wheels as standard now, because of it's increased brake sizes. So, i discovered that the front brakes on the 330 are 326mm. I got my trusty calculator out, and discovered that that works out to 12.8"!!! Now, i would think that BMW would improve it's brakes for their premier 3-series, but now it appears that the //M has the same damn part! Anyone with some knowledge on this, please help me out here.

all BMW brakes suck for very heavy use like driving schools and I am sure E46 M3 owners will warp rotors. M5 guys in Europe already discovered those brakes are inadequate for autobahn runs and track events. Lots of them already went to AP Racing or Porsche.
