Default 275/40 18 rear fender rub

Not sure if I'm posting this on the right spot, but I got a problem. Just put new 18" foose legends on 96 camaro. 275/40 in the rear. Not sure if it matters, but the car was originally a v6. (v6 vs v8 suspension). Tires are rubbing outer fender lips whenever the car squats. Bumps, dips, launches, and even an average sized back seat rider are big NO NO's right now. Also cornering.

My question. What is the best fix? Shocks, springs, or both?

I don't really want to raise the rear cause I like the stance as is.

What's their offset? If its a low offset then they will stick out of the car more. I did a search on foose legends and I keep coming up with "for Mustang".

In any case, you could roll your outer fender. Though you will probably want to touch up any paint that flakes off or make sure you heat up the fender.

Yea what is the offset? I just checked those wheels out-looks like a nice looking wheel but doesn't look like they are made with enough offset to fit a F body correctly.If you only have 5" or so offset they are going to stick out and hit the fender lips.

Let me guess... its rubbing on the driver-side wheel well, right? Passengers aren't a welcome sight either Id imagine. *chuckle*

Well, I had the same problem. Install an adjustable panard bar and shorten the adjustment so the the left rear tire doesn't shoot out of the fender whenever you make a hard right-hand turn or compress the suspension. A watts link will work even better if you feel like spending the cash. It prevents the axle from walking to the left side altogether.

Ive got one that im going to sell. Let me know if you want it.
$95 + s/h and its gone.

That's true. If the other side clears the outer fender by quite a bit then you can throw on an adjustable PHB to pull the rubbing side in.

I'm not sure on the offset. But I did specify to the sales rep the type of car I had and I didnt want any issues. This is the wheel he recommended. I'll check with him tomorrow to get the exact offset. Also, I don't have bump stops on the car.

The tires seem to be flush with the top of the fender and the wheels have about a 2" lip.

I also think he should get bumpstops but I don't think it will prevent the rubbing. I'm sure he's rubbing before full compression travel assuming bumpstop is there.

Same thing with springs.. that's just a bandaid. Full suspension travel will still put him into the fender. Cars hit full suspension travel all the time.

To me it sounds like the only way to get around this is to either roll your fenders to allow the tire clearance.. or sell your wheels and get the correct offset. The first option might work.

That sales rep carid or whoever unfortunately seemed to not know what he was talking about. I think he probably matched your bolt pattern and didn't care about the offset.

Wheels have a 34mm offset. I don't think the car ever had bump stops.

Considering a zr1 replica 17x9.5 inch wheel offset is around 56mm.. yeah you're offsets are way off. Either you'll need to roll/flare your fenders to fit them or get a set of wheels that fits the car.

AHHH... I just noticed something. I'm an idiot. You have a taller than stock overall tire diameter! Any reason for this??? Or is this just what the guy told you to get? It's possible you will reduce the rubbing by quite a bit if you get the correct sidewall size which should be 275/35/18.. closest to stock height. No guarantees though.. you might still rub.

I actually thought the offset was pretty close to correct. 56mm would stick wheel/tire further out wouldn't it?

Nope, more offset means the rim mounting is further away from the center of the overall rim.

So more offset would tuck the wheel further in? I'm confused

I have the same issue with an 18x9.5" +35mm offset in the rear. It looks great, but I scrub from time to time.

Guess I need to update my signature picture.

It looks like rolling the fender lip is the best option. I also don't know if the V6 rear springs are softer than the V8 cars, but I only hit on bad bumps, or high speed dips.

So, is the 54mm offset like on the zr1 replicas what I need or is that the corvettes offset? The guys I know that used corvette wheels
Had to have spacers.
