I'm investigating some 15x7 Rally rims for my '65 Chevelle that the seller says have an offset of 4 3/4". I'm interested since my car is lowered 2" and my 235x60 tires rub the outside front wheel wells with my current 15" Rallies. Has anybody heard of Rallies with a 4 3/4" offset, and know if they will clear front disc brakes?
