i think the stock bullitts are 8" wide. i'm satisfied with the fronts but i want to fill out the rear wheel wells. are the 9" enough or do you need the 10 and a half inch. does anybody make the exact looking rims just wider? or does the paint not match factory? my car is mineral gray so i want to keep the same color rims. also does anybody have 18" in the rear and 17" in the front? does it look stupid?
