Update:
18" 237 style wheels is a
YES fit on my 530D with front brake upgrade from the 760i WITH spacers (can't recall if they are 12mm or 17mm) but you need spacers for them to work..
760i rotors and calipers
Once I paint the rims and calipers I'll post pics
20" replica wheels were a pain to drive with, many potholes. Found this 237 wheels used with tires for $300 usd on a shop.
Reason I post this is I've seen people stating here that it doesn't fit.
