Default Need help please!!!!!!!!!!!

I have an 05 c6 and just put on aftermarket wheels and tires on. the diameter of the wheels and tires are the same as factory, but the offset makes them stick out past the wheel well just a little. I love the aggresive look but now when i go over a bump in the road my tire scrapes the wheel well. Is there anything I can do? do they make spring spacers for vetts that will stop the spring from letting the car hit my tire?

I believe going back to standard offset wheels would be your best bet, or buy the wide body fenders to go with the wheels.

feel and look where the tire is hitting the rear panel. it is probably starting to take the paint off. i had the same problem and had to switch back to the proper offset. i know it looks good but it should be addressed and corrected asap. you may even notice that one side (usually the right side) sticks out more than the other. messing around with your suspension is not the answer. just my .02 cents worth.

Just raised the car with a jack, look between the spring and the upper arm, turn the little bolt at the end of the spring, you will have to raised the springs a little to release the tension on the bolt( the bolt passes through the spring and has a round rubber at the other end) use a 10mm wrench to turn and when you turn it clockwise the car will raise and you can raise the car a little to avoid the wheel from touching with no problem.

Thanks Trinic5! I knew there had to be a reasonable solution.

You know, that is really a band-aid fix for the problem. Ideally, you should have gotten the correct offset. If it were the other way around, you could do wheel spacers. You don't have much in the way of options. The only way I'd make that sacrifice (raising a vette ) would be if I were needing to stuff some BIG rubber under the stock fenders for drag racing. But then again, I'm really not into the whole 70's look.

and if you are going to go that route don't forget to get an allignment.

How do you do that would improperly spaced wheels?

Not sure if I really understand what you mean, but the improperly spaced wheels by themselves won't cause any alignment issues, and the car can still be aligned with those wheels installed. It is the alteration of the ride-height that will affect the rear camber, which in turn changes the rear toe. A change in rear toe can affect thrust-angle (relationship between front and rear axle centerlines). Any time you change ride-height, an alignment is a good idea.

good advise there andy. I wouldnt get to crazy with the offset and as long as your alignment guy knows they are offset he should be able to compensate. I aligned a drag car once with skinny frontrims and tries and wide rears. The alingment machine said the rears where really "towed in" do to the rears being so much wider. Most cars the front and rear tires do run pretty true front to back or an aligment machine when you enter ID the vehicle will know and compensate for it. Again lower or raise and it will change the camber and possibly toe. This is arguable because with the bump steer effect it really shouldnt change. Thats another topic tho, lol. paul

Either way you are still risking cracking your fenders if you hit a bump hard enough.

Well the wheels are made for the car, but I went a little wider on the tire which I think put me over the edge. My vette does have 60k miles on it and I heard that going with the heavy duty bilstein shocks it would be stiffer in the rear and may solve my problem. If not Im just going to get the z06 fenders and be done with it. I love the wheels and after having them put on, the car corners a hell of alot better

You're using the bodywork as a bump stop. During transitional maneuvers and when hitting irregularities in the road, your fenders are supporting part of the weight of the car, and more importantly, the springs aren't.

This is very bad news for your fenders, for your tires (which will get shredded if you drive fast) and most of all for handling because weight transfer spikes when you run out of suspension travel.

Lengthening the existing bump stops is a non-solution, and I assume raising the car a few inches isn't, either.

If the goal is better handling, definitely go back to the old wheels. If the goal is looks, well... be careful.
