Wheel Backspacing
I'd like to know what other '55-57 trucks with Camaro/Firebird/Trans Am front clips are running for front wheels, sizes, backspacing, offset, etc.
On my '57 I've got American Racing Torq Thrust II's, 16"x8", 4" backspacing, zero (0) offset, and 225/50/16 tires. The wheels sit about flush with the fenders (approximately half inch of gap between tire and fender) and are tucked about a half inch. With my current setup, I can't turn the wheels full-lock without the tires rubbing the fenders. I'm perfectly happy with the truck's stance and not interested in raising the truck. I'm also perfectly happy with my original front fenders and have no desire to cut or roll the inner lip. I believe my only option is to get a wheel that sits a little deeper in the wheel well. There doesn't appear to be an off-the-shelf Torq Thrust II wheel spec that will work to get me the clearance I need. Les Schwab recommended a custom, 2-piece Torq Thrust II with custom backspacing. Two custom Torq Thrust wheels with tires is easily over $1k so now I'm browsing for other wheels. Interested in seeing and reading about what others are running for wheels. Old picture of the front wheel and how she sits: |

Re: Wheel Backspacing
Mejum, I am just in the mock up phase of mine (again and again), but with a 2nd Gen subframe I have Boyd's 18 x 8's (zero offset, 4.5" back space) with 245/40/18's and can turn stop to stop without rub. The Boyd's are just old rollers, so I am looking at some new ones now. AR VN515 18 x 8's state 4.5" back space too. Their 16 x 8's should have the same back space, I would think.
Cheers, Jim |

Re: Wheel Backspacing
There isn't going to be any free lunch in that deal but what about shorter control arms to move the wheels in the needed amount rather than a wheel change?
To me those wheels look perfect on that truck and I wouldn't want to be changing them or the offset on them as the wheels that don't have that little bit of offset look rather hokey to me when they are on older trucks

Re: Wheel Backspacing
I'm unable to run 16 x 8's since I've put a BBC in my 56 and 2" dropped spindles. so I'm running 15 x 7's, but I'd suggest talking to Rocket Racing Wheels. I found them with Summit racing and they helped me to locate the right backspacing which I've got 4.25" on mine. I'm running 215/70/15's.

Re: Wheel Backspacing
Some follow-up: I ended up going with a 195/60/16 tire and it got me the clearance I needed while maintaining a similar overall wheel size.

Re: Wheel Backspacing
I think that tire will be too narrow for that wheel. Take a corner hard or hit a bump could brake the bead and tire could come loose. I hav seen it happen on the rice burners.

Re: Wheel Backspacing
you may not be interested in this idea, but, have you considered rolling under the inner fender lip? I made my own tool to do this but Eastwood sells a great tool for this very problem. you may be able to go back to the previous tire setup. food for thought
