I was looking for new wheels because of the 4 to 5 lug conversion. I know the car stock has a 4.5in backspace, but the cragar ss wheels I was looking at, 15x7 have a 4.125in backspace and the 15x8 have a 4.25in backspace. I know if it went the other way I could put spacers in, but is this less than half an inch of difference going to cause an issue or not?

 

it depends on what front brakes you use backspacing is from the back of the rim where it mets the rotor/drum to the edge of the rim as long as your not runing 4 or 6 piston cailpers they should fit

 

I'm going to be using a stock 99-04 disc brake setup which is only 2 piston, so it should fit?
