This looks the place for any wheel questions, soory if it's been asked before. I'm looking at a set of BBS CH-R wheels and the US site I'm looking at can only supply 20in in a 5X114.3 stud pattern. So they're a 20 X 9 ET40 (pos offset I'm guessing) for the front, and a 20 X 10.5 ET24 for the rear. I'm not too worried about the rear but I'm sketchy on the front with the guards. Anyone running this size up front?
