88 Formula 350 wheels offset and backspace
I am a new member not sure if I am not sure if I'm in the right category? Can anyone tell what the offset and backspace is for a 1988 Formula 350 for front wheels and rear wheels? There is approx. 2 inch lip on front wheels and 3/4 inch on rear of factory wheels, I want to buy 16" american racing torq thrust 2 wheels but I dont want them to stick out or rub. I would like them to sit even... like factory? Does anyone have American Racing 16" wheels on a formula are they 16 x 7 or 16 x 8 etc. , and whats the offset and backspace. Thanks
