Reviving my old post. FINALLY got a chance to test my old F30 3er winter setup on my F23. Looks like it fits fine, without any spacers!!! **note the pics show OEM 17" Star spoke style 394 with 225/50/17 front and rear ET37 Bridgestone WS80. (these came off of a F30 non-M-Sport brakes).
I will be dropping down to 225/45/17 rubber this winter on my 2 Series. Not the nicest wheels on a 2er, but I'm stoked I don't need new rims
