Depends on how practical the car will be. I run 18 x 11 on the rear with 275/35/18 toyo's and 9 x 18 with 225/35/18 fronts and i wish i'd gone an inch bigger all round with the width and size. Saying that my kit is very wide. If you car is standard, then i'll go for something like 18 x 7's all round to be on the safe side. A lot will depend on the style of wheels you choose as well. Good luck
