I am wanting to order a set of Weld Prostars for my 1980 Camaro. I want to order 15 X 8 for the back and 15 X 3.5 for the front. I need to know what backspacing I need to get before I place an order though. I was thinking I need to have a 4.5 inch backspace for the rear but I'm not to sure for the front. Thanks for the help.
