So I just ordered a set of 17x9 cobra rims (wide body life), the bore on the Fiesta is a belive 63.4mm and the bore on the new wheels are 64.2mm. I cant find any hub centric rings. Did i just screw myself or will the lug nuts keep the wheel in place just fine. I read a similar post on a porsche forum everyone said the lug nuts by themselves will work. What do you guys think?
