I am looking to buy a set of wheels that are 18 x 8.5 front offset 15..rear offset is 35..these are coming off a 91 740il..it appears the hubs are the same..and I am pretty sure the front offset is no prob..will the back wheels work with a 35 mm offset...i know optimum is around 25mm...can I or should I run the backs with a 10MM spacer? Thanks.

Rear with spacers will be fine but many advocate against spacers with the E31. I can however be done.

A 12mm spacer is needed for the rears. Make sure to get the associated longer bolts.
