Sal, thanks for taking the time and posting the results. I'm opting to go to about a 29" diameter tire, 20x8 rim with 4" backspace, which if my math is correct will yield just under 1" scrub radius. My next concern will be if the tire will fit inside the wheel well without rubbing. I'm currently running stock new ece coils with a ece 2 1/2" drop spindle, 72 and up thick stock rotors with 15x8 factory rallies with about 4" backspace and a 26 1/2" diameter tire. If you feel the hub face is in the same spot as what you are designing i will take my existing tire and add additional dimension to it and check for rubbing. Thanks again for your help, Brian Fuller
