Congrats! Mine arrive Monday.
By chance does anybody know if the anybody had a machine shop machine down the mounting flange on the rear wheels so they would accommodate a 305/35 DR? I figure by machining off 1/4"-3/8" off would allow clearance for such a tire on a lowered Shelby.
wow, you really want to weaken the flange area? 1/2 inch is the correct number......3/8th might be close with 305's but doing nothing will get you rub with 305's. Shorten the rear end is the smart thing to do or buy wheels with the correct backspacing. Alcoa's are wrong by 1/2 inch, front and rear.
