They are American Racing Wheels. Fronts are 15x6 with 4" back spacing The rears are 15x7 with 4-1/2" back spacing. The car has an 8-3/4 rear end with aftermarket axles and no adjuster on the passenger side axle. There is hardly enough room to get my fingers between the wheel well lip and the rear tires (I don't have great big hands) it doesn't rub but there's NO EXTRA ROOM. I'll try to get better detailed picture of the fit and post them.
