Are you going 275/45/17's on the rear? Will that fit the stock rim and will it rub the wheel well or shock?iron_horse31 said:I've already started with the mods even before my GTO has arrived. I ordered the induction kit from ls1speed. Next is the CAI then maybe a set of electronic cut outs. Finally for the year is a nice set of rims and tires. I'm leaving the 245's on the front and going 275's on the rear. Next year is a whole new ball game.
