Trying to figure out if I'd have clearance here. The rims are 16x7.5 and have a 5.5" backspacing. If I go with the spacers from MustangsPlus(1") I'll have a 4.5" backspace. The car will be sitting on 1" drop springs in the front. Is 4.5" the backspacing I want for a 225-55-16 tire? Anybody else running 16" wheels? If so, what's your backspacing and tire tread width? Have you lowered the front end? I'm concerned about hitting the suspension/steering joints more than anything. That's VTstang66's fastback running the same rims. He told me his spacers are 1.25" but could be smaller since they rub the fenders a little. I'm looking at 1", but I don't want it to go too small and rub something on the inside. I'm also considering dropping down to 225-50-16 tires all around to get it closer to the stock tire's diameter and provide room for the 1" drop. Good idea?
