First off hi im new to the sight thanks for taking time to help. I am finishing my 81 cutlass build i am leaving the stock springs in. The car has the 442 ground fx on it so probably not going to lower. The rear has an 8.5 rear that is about one inch wider than stock on both sides. Front is all stock. I am going with crager soft 8s in 17 inch. I do not want any rubbing at all. I need to know how wide , how much backspacing, offset i can fit. I want as much rubber as possible height and width wise. looking for a more pro touring look. Pics of your ride would be appreciated also.
