After reading over this whole thread I'm glad towards the end someone brought up the rack of a spacer for front fitment clearance issues. It's not rocket science. I can pretty much guarantee you I could get these to work up front on a non m with a fender roll (e90) or a fender trim (e93,plastic) and a spacer. Especially in the 9.5" size.
