Yes, cross drilled and also they appear to be a floating rotor, they are 3lbs lighter(fronts only) and also cool better than normal rotors. But they are same sized unlike e46 m3 bmw performance ones, which are better than stock m3 rotors.
Part#s are: 34112282871 & 34112282872 for the fronts.
They are not listed on realoem.com
But you can find them here by part#:
or bmw usa(canads doesn't have anything listed):
