Those wheels have a bunch of backspacing, I'm not sure but I think it's around 7". To run those wheels you will need to get some of those bolt on wheel spacers. Vette Brakes sells them, you'll probably need around a 2" spacer. I was thinking about using these wheels on my car too, but have decided against it. I have a freind who has a 97 or 98 camaro SS with these wheels and I was going to take them off his car, jack my car up so it was at ride level, put the wheels in there where I wanted it and measure the distance from the wheel to the brake and then I would know exacty what wheel spacer to buy. Maybe you could find someone to let you do this.
