2004 MCS with stock sport suspension. Will 215/45-17 BFGoodrich g-Force Rival on OE s-lites rub? If so, will spacers fix?

 

No rubbing issues and no spacers necessary. 215/45-17 is a great replacement size....and IMO looks better than the stock 205/45 size because of the slightly wider stance. I have that size on my 06 currently and also used them on my r56 when I had it. You also open yourself up to many more tire options when changing to that size. Go for it.

 

nope. but if you add a spacer you might rub a bit
