328 rotors are larger than 323 by about 1/2 inch. The examples at BMW's ultimate drive had no warping problems. I asked the instructors and they said they haven't had any problems. Not exactly a track but a square autocross course that took about 18 seconds to get around and let the car get well into second gear.

: : My primary concern are the brakes, everything else I would immagine to be fine, although going from a dry sump motor to a regular wet sump also is of some concern for me. Is there a baffle in the oil pan?
: I don't know, but I've NEVER heard of anyone with a contemporary Bimmer at a school I've been to losing an engine.
: I've read posts here about possible warped rotors, but the 328i has ventilated fronts AND rears. If you warp them, you can buy some of the sexy looking aftermarket cross-drilled rotors advertised in Roundel.
: (only a car nut would think cross-drilled rotors are sexy looking).
: My 328i sport/premium arrives sooner than expected (1/11 at the port, 1/15 at the dealer), so now I have to see if I can get into the school at Thunder Hill!
