Inner fender rub-a-dub-dub

Hey guys. This is my first official thread! I only wish it was on better circumstances. I got a 1968 Camaro a while ago, and it's one of the most beautiful cars Chevy ever made. I just bought some new American Racing wheels and tires (http://www.summitracing.com/parts/are-3097861/overview/) and, in a nutshell, my cars front suspension seems FUBARed.
I'm going to try and post pictures, but to be honest, I'm not too computer savvy and am not sure how to do that yet.
Anyway, I need new coil springs because the fender lip only sites approx. 1 in. from the top of the tire on the pass. side, and 1.5 in. on the drivers side. (I know, crazy, right?) the wheel is 17" and has a backspacing of 4.5". the tires (the tire guy told me they would fit) are 235/50/17. It rubs the subframe on full turn, and the rear inner fender and bolt whenever I turn. I feel as if I can run these tires with some sort of adjustments, but I don't know what those are yet. Maybe someone can steer me in the right direction?

Re: Inner fender rub-a-dub-dub

Upper and lower control arm bushings if worn can cause plenty of issues. I would also check body mount bushings.

I can't say for sure but I am thinking a 4.5 back space for the front is too much? Sorry I can not remember. I want to say 4.25 or 4.0?

Also What alignment specs did you use?

Re: Inner fender rub-a-dub-dub

Joe Harrison, Thanks for the reply!
I'll check and see how the control arms look. I put the pic of them up to see if that made any impact. The American Racing website lists it as a fine fit for a Camaro, (btw I forgot to mention this but the wheel is 8in. wide).
I'm not keen on shelling out much more money, but I think moving down to 225/45/17 on the front will help a lot, and getting button-head bolts for the fenders. I hear people talking about "negative camber gain" helping with tire clearance, but don't really understand suspension geometry that well so I'm not sure I want to meddle with that.
To be honest, I'm not sure what alignment specs were used. "The tire guy" did what was "recommended", the numbers escape me at the moment. Could the wrong specs cause rubbing?

By the way, I'll post good pictures of the car later when I can get a decent sunny day, and some time. the wheels definitely made the car look better.

Re: Inner fender rub-a-dub-dub

If you check out forums and wheels and tires on this site you will see what size tires owners are installing on their Camaros. I think the the tire guy gave you the wrong recommendation. I see 225/45/17 and 235/45/17 and some say the 235/45/17 rub. For the rear tire size 255/40/17 and 275/40/17 The wheel sizes are 17 x 7 with 4.5 B.S. and 17 x 8 with 4.75 B.S.

Re: Inner fender rub-a-dub-dub

I have 235/45-17 on 17x8 rims with 4.5" BS. The tires rubs the subframe at full turn. The tires do also rub the inner fender bolts at the fender lip, but my front end is lowered (I have 14.5" between wheel center and fender lip). Change to bolts with rounded heads (I think you call them fillister head bolts).
Also acc. to my opinion a 235/50 tire is on the maximum limit. A 235/45 will leave a gap of approx 3/8" to the inner fenders compared to 235/50 tires and that might be all that is needed to get rid of almost all rubbing.

Anthony,

The safe sizes to stick to for 17" wheels are 225/45/17 for the front and 255/45/17 for the rear.

Front and rear wheels have 4.5" backspace.

If you go bigger than this you might get away with it. Maybe.
