There's also a one piece cross drilled rotor option from the 330 that also fits the 3.0si since the 3.0si front brakes are actually 330 calipers and rotors. Obviously it's heavier than the two piece rotor, but it's also quite a bit cheaper since you can get it from multiple aftermarket sources.
Is the hub assembly the same? Any ideas?
