Ok guys need some help here....

First the issue...I am rubbing the drivers rear tire on the lip of the fender....no problem on the passenger side.

Second....just got back from the alignment shop and could not get anymore than -0.4 deg. camber on the questionable tire (rear drivers side) while keeping toe within spec .1 deg. There was plenty of adjustment room on the rear passenger side and easily could have got -1.5 camber and zero toe.

Here is my suspension setup:

Megan Street coilovers: set to ~13" from the center of the rim to fender lip on both sides in the rear. front height adjustment ~14"

Tires: 245x40 18 Falken 615s

Wheels: Volk GTUs 18" 8 inch wide (i think they are +36 offset)

Note: I did hit a curb rather hard awhile back on the questionable corner and had to replace the wheel. I can't see any damage to any of the linkages....is it possible that the entire rear end has shifted or something.... How would I be able to tell....would this account for my current issue?

 

Yep. Something is bent back there. I had the same problem in the front, and they replaced everything under there. Was still getting a wobble. Found out it was a slightly bent axle as well. Something under yours is bent for sure.

 

bump...request for additional information.

Any guidance as to what to inspect closer?

 

The first thing to bend are the aluminum parts under there that are meant to give. Control arms, trailing arms, stuff like that. Im not suspension guru, but those are where I would look. Think of it this way. The curb hit the wheel on the bottom, thus forcing the top of the wheel outward toward the fender lip. This would be the equivalent of positive camber.
So think about what force would have been exerted like the picture shows and check the suspension accordingly.

 

I think it'll also depend on how you hit the curb, and how fast you were going... for example, if you were trying to power slide and your rear wheel slammed into the curb, it could be something as serious as a bent axle. If you were going around a corner, and got too close, it may just be one of the arms under there.

If its slight, you most likely won't be able to tell visually... but you should probably start by jacking up the rear driver's side, pulling the wheel off, and checking things out. Good luck.

 

Thanks. I have been under the car several times trying to figure this one out. Additionally, the shop I had attempt to align the car spent about 4 hours trying to figure it out. Nothing is noticable.

It was wet out and I lost it. Spun around and hit the drivers side rear on the curb. I wasn't going that fast maybe 20 on impact but it stopped the car dead. What I have been toying with is the entire rear assembly might have shifted. Any ideas on how to check this out?

 

No matter how many times you look at it. You won't see the bent of by eye.
2 things that could be bent.

1. spindle
2. lower control arm since this adjust your camber. <--I'm more leaning to this since it's made of aluminum ( easy to bend )

Start replacing parts and get her straight.

 

it can be a damage arm or damage bushing, even though it not visible you are only dealing with 1 degree of adjustment so the damage wont be visible to the un experienced eye so the things i would look at are:
1: camber adjustment bushing
2: toe adjustment bushing
3: lower control arm
4: toe adjustment arm
