TIRE FITTING PROBLEM

I just got some new wheels for my car and they came with 1/4 inch spacers. I drive a 96 gt and the specs of my wheels and tires are 18x10 with Nitto NT555 285/40/18 for the rear and 18x9, 275/40/18. At first, my right rear inner wall of my new tires were rubbing against something and made a squeaking noise and I got one of the exhaust hangers moved since it was bent too close to the tire. I got that problem solved and test drove my car, but still it made that noise. One of the mechanics took off the tire and noticed that a section of the inner wall of the wheel well was bent in from the tire, so he beat it back with a hammer so I had some clearance. It helped, but I noticed that when I make sharp turns or fast, left turns, or even just turn the wheel all the way, it still rubs something here and there. I've been outside working on my wheels for the past 2 hours this morning and noticed that the left side sits out just a little more than my right rear, which gives a great amount of clearance. What would you guys recommend to help solve this problem? I was thinking about putting on some 1in billet aluminum wheel spacers to push both wheels out some to allow more clearance on the right side, like these http://www.americanmuscle.com/1in-billet-aluminum-wheel-spacers.htmlbut would I have to do any type of modification to get these to fit well? Please leave any comments or suggestions on how I could fix this problem. Thanks guys

nobody?

The left side sits out more than the right because your rear end isn't centered in your car. Get a panhard bar so that you can center it and see if that helps with the rubbing.

I think that's the problem to be honest. My dad used to drive a camaro and had the same problem. I'll look into getting one to help solve this problem.

These wheels are actually mustang wheels. They're sold on American Muscle and they are the GT4 wheels.

I'm not sure. I got the car about 6-7 months ago and was only told that the past owner had hit a deer, which damaged only the right front of the car. He replaced the fender, got a new windshield, and added a new paint job. I noticed after a few months though that the right pipe sat a lot lower than the left. I realized that the hanger holding the pipe wasn't as curved as the left side, so I figured he had backed into something that pulled the hanger down. I got that fixed, but it still makes the noise. Then my dad told me about him having the same problem with his camaro and if you look at my car from the rear, you can tell that the left rear tire sits out a little further than the right, and you can also feel the clearance with your hands.
