Pulling this from the OP's original thread:
Fronts: 19x9 ET20, 265/35ZR/19 PS2's
Rears: 19x11 ET32, 295/30ZR/19 PS2's
With that being said, this is NOT a direct fit for the 3 series. The front is far too aggressive for an E92 but can work on an E90 with a serious fender roll/pull. You will also need to purchase a new set of tires and run a 235/35/19 up front and 265/30/19 in the rear at a minimum.
