there will be no back seat, im not sure what we are putting back there yet, tracey weaver, who is doing the interior, has some really good ideas, so i'm just letting him run with it. the wheels/tires in the back will be 20's, im not totally sure yet what width rim, probably 12 or 13" wide,,,but tires im thinking 315/35/20 or 325/35/20. there will be 19's up front. I was using a 295/45/20 as a guide or mock up tire to double check everything, and that looks lost under there lol, so there is plenty of room.
