I have a 1978 Z28. I lowered the front 2 inches and the rear has not been lowered yet... I am goin with 17X8 in the front and i want to run these in the rear-
18 x 9.5 with 5 x 5 5" or 5 1/2" inch
Will the rears fit without hitting the leaf springs?????

I would think you should throw that question at the manufacturer of the wheels you intend to use.
