Excellent, if the E36 m3 front rotors are 60mm then the E36 m3 master cylinder should be more than enough for the E46 330i calipers piston @ 57mm! Braking and revmatching for donwshifts has become harder because I have to push the brake pedal further Also has anybody figured out a way to adjust braking bias? E46 330i All E83 X3 All 320mm can be used only with 325mm front as you don't want to have your rear rotors bigger than the front. Although many variables go into calculating brake bias, the disk size ratio of a 325mm front - 320mm rear conversion is similar to what the 3.0i has so it should be fine.

Yes, an E31 840ci front calipers. The regular M3 brakes have 28mm thickness and the 330 have 26mm of thickness. The M3 brakes would be better, marginally, for fade resistance, that's about it. More so if you went with Euro floating rotors. The stock brakes are single piston and rather useless.
