Wondering how much clearance you have from rear wheels to quarter panel? I was talking to a guy at chassis cert. day last year who has a 70 Camaro. his slicks where purdy' close to the lip of the qt. panel. just wondering how much groin' room I should give em. i've got 33x22.5x15's. Rubbin' the sheet metal at the far end of the track would problee' be a bad thing
