I bought two 17x8 AR Torq Thrust M wheels with the anthracite centers... these are for the front of the car but I want a wider tire on the rear. So my plan is to buy 17x10.5's for the rear in the backspacing for a 4th gen camaro. Will these wheels bolt on, with no spacers... with a LS1 rear end? The backspacing is 7.5 in., which after measuring would seem to fit but I'm not exactly sure how much wider a 4th gen rear end is compared to my 9 bolt.

Just looking for a definite before I pull the trigger. Either I'm going to run the 10.5's or a 9" rim on the rear... as I'd like at least a 275 tire out back.

Thanks
