Hi Crash,
Looking good. I worry I may have a problem and wonder how you are addressing this. I believe you widened your rear fenders and this will allow for wider tires. On my car I have 345's on 20" 13.5 wheels but to get the wheel out to the three inch widened fenders the wheels are "deep dish" with an 8" backspacing. Can you share your plans around wheels and offsets?
Thanks,
Gary
