Looking at the Boss 338 wheels for my 68 Camaro. The rear will be a 18x9.5 with a 5 backspace. My car is still on the rotisserory and I'm not scared to do any cutting and welding . I have a 9" Ford rear that is 58.25 wide that I will be putting LS1 disk brakes on, so it should be a little wider. If I am doing my math right, a 5" back space should be about perfect with this setup. It should give me enough room to be able to use a small spacer to get the wheel out just right. Does this sound right ? Also thinking of running a 295/45/18 Nitto on the back. I know this is a big tire ( 28" tall ) but I would really like to get the tire to tuck up in the quarter a little. I know that I'll have to modify the tubs some but do you think this is even possible or has it been done before?
The 58 is outside axle flange to flange. I know that 60 is the stock width. I am thinking about putting the shorter rear in it and going to run less backspace for a deeper looking wheel. I've got a stock 8.5 10 bolt posi rear and a ford 9" that is 58.25 wide. Just have not made up my mind on what to do yet. Would love to see a 28" tall tire under a 68. I don't mind cutting the tubs and modifying them so I can get the tire to tuck a little in the quarter. The car is going to be a custom anyway. LS1, 4l60, ford 9", 02 interior, blah blah blah.
