The rear wheels will need 10mm spacers to fit flush with the fender, but the fronts will stick out a little bit, I have tried oem m5 e60 wheels on my x5 and the rears were fine but the fronts stuck out way too much. I sold the wheels and invested in oem style 87. If you do get these wheels, you will most definetly need to get the fender flares for the front and rear, and use 20mm spacers for the rears. Its alot of work, my advice is to you is to just pass.

Twinspoppa is using replica 20 inch e60 m5 wheels with the same offset and width all around.
