I found a set on CL and it's off a 4 series (F32). All he mentioned was that the sizes are 20x9.5 front and 20x10 rear. He doesn't know the offset. Anyone know off hand if these will work? Thx

Request a picture and brand to check it online. The 9.5-10 are too wide for the modest stock F32 wheels of 8-8.5 http://realoem.com/bmw/enUS/partgrp?...MW-435iX&mg=36 Therefore if these are aftermarket wheels, they may have a custom offset. If catalogues will not help, a tire shop can measure it.

I just went on the Niche website and I think the wheels are most likely 20x8.5 and 20x10. From the options on Niche, the offsets for the 4-series are most likely ET35 front and ET40 rear. Will these work? Thanks a bunch.

The 20x8.5 et35 and 20x10 et 40 are fine. You could then add spacers 8-10 mm all around to have the wheels sit flush to the fenders.

I am running Vorsteiners VS-310 20x8.5 et20 and 20x10 et28 with perfect fit, pics are in the profile album.
