E46 323i/325i/328i/330i: the E46 has more room for wider wheels than the previous E36. For the Spec E46 series we use a 9.0" wheel on the front and rear and they clear without issues. A 9.0" wheel and 255-265 tire should be all you need for grip in this car. A 9.5 or 10.0 in the rear is also possible if you want to do a staggered set. This brake package for the E46 330i, 330Ci, 330xi comes with everything you need to perform a major brake overhaul - Rotor Options:aftermarket Made in Complete Front & Rear Brake Package - E46 330i/Ci/XiE36 M3 front caliper pistons (60mm diameter) are too large for an E46 330i front caliper, which has 57mm pistons. I don't know the size of E46 M3 pistons, but they're probably at least as big as the E36 M3 pistons.
