Have you considered OEM base F80/82 style 513m wheels? Same width and offset as the OEM M2 19's, but in a lighter (and more attractive IMO) 18" forged wheel.

If you wanted to run a square setup you could probably pick up 2 sets and run all 4 rear wheels with a bunch of camber in the front, and sell the remaining 4 front wheels to someone with a narrow body 3 or 2 series.
