I have a 67 Camaro with a 396 in it that I am having some minor rub issues in the wheel well on the front passenger side.It is originally a 327 car. The car has 225/60/15 Radial T/A`s on 8" rims with a 4" backspace ( all the way around ). The car has had a disc brake conversion on the front, in addition to the front suspension being completely rebuilt ( all by the previous owner ). The front tires completely fill the wheel wells, while the rear has about a 3" space between top of wheel and top of wheel well opening (as veiwed from the side).The car also sits slightly higher in the back. I do not know much about what exactly the previous owner did to the car, but it almost seems like the front end was dropped a little bit. As the car sits, it drives and handles like a dream so I would hate to screw anything up. However, the rubbing issue needs to be fixed and it would be nice to get the car to sit more level and the gap between tire and wheel well opening more symetrical. Also, why would the front tire rub on the passenger side and not the driver side. It seems to rub on the bolt heads just inside the wheel well lip on the tops, and only does it when I hit a dip, bump or ripple in the road. I think a 4 1/2 " backspace might pull it in far enough to fix that problem, but not sure. Any advice on how to preceed? Anyone else ever encounter this problem? Help.

dfraz,

There are many with 1967's & 1968's who have encountered the same issues you have. Heck some with 1969's have as well. IMHO the best thing to do is put a 15x7 with the stock backspacing on it. I wasn't born yet when the 1967 Z28 rolled out of the factory but I believe the 1967 Z28 had E60x15's on it. This equates to P215/60R15 in a radial tire. I think in 1969 they went to F60x15 which equates to P 225/60R15 in a radial tire. Both the 1967's & 1969's and yes even the 1968 Z28 rode on 15x7 Rally's.

The 4 1/2" backspacing may be enough to fix it, but if you are going to change wheels I would go with a 15x7 Rally with the stock backspacing. Too many people in the tire & wheel thread have commented about issues with the 15x8 on all first gen's up front.

Good Luck!! :thumbsup:

8 inch wheels need 4 3/4 inches at least, ideally 4 7/8 inches of backspace (watch for rub on the frame). sounds like a wheel issue, not so much a tire issue. my 'bird does the same, only on the passenger side! go figure. on an interesting note, i took it around the block (very aggressively; sorry neighbors!) and had placed masking tape over the bolts to see if i could see 'witness marks' on them when i induced the rubbing. believe it or not, the tape was untouched! mine rubs in the wheel well just inside the fender. you might want to check yours to be sure, but lacking that much backspace, it probably is one of the body bolts. good luck and let us know what you find out!

Thanks for the advice. I will try the tape idea, that sounds pretty good. I think going from 8" to 7" might be the sure fire solution. What is the backspace on a stock 15x7 ralley? Would putting my current tires on 15x7 increase the overall height of the tire?

Does anybody know where I could purchase (2) 15x7 rally`s (Rims only) with 4" backspace? I checked a lot of sites and the only one I could find was at Ecklers and it looked like some generic one that had a bunch of bolt holes, so it would fit multiple cars. Thanks.

wouldn't 60 series be a better choice? or a 215/70 or 205/70? those tires you describe seem awfully tall...
