Well I know that I need wider wheels & good tires, this car has OE suspension. I don't know if only relocating the leafs will allow for a 10" wheel with proper offset, which will be fine for me because I can get a nice tire or if I need to do more drastic work than that, 4-link which I rather not do. So, I guess the question should have read what is the widest wheel that can be used on a 68' FB Barracuda with OE suspension? This is a street strip car.
