Is this normal, or tweaked? DD wheel offset...

I recently got my Bullitts mounted on the car. Two factory 17x8 up front and two 17x10.5 out back with 315/35/17 Sumitumo's mounted to them.

The first day or two I didnt notice this, but it quickly caught my eye soon after that.

The right rear wheel/tire sticks out to the side about an inch more than the left rear wheel/tire does. The wheels arent different in their offset or backspacing, both tires are the same size. The left rear sits nearly flush with the fender lip, unlike the right rear which sticks out past it.

I know on my Jeep when I lifted it, the geometry of the suspension and steering components (mainly the track bar) caused the axle to shift the same direction, and producing the same result.

Could this be the same for the Mustang, but since its lowered? It doesnt make sense though because the rear axle is firmly bolted up there, no steering components or anything (duh).

So is this normal or is this a problem? If its a problem could the stock control arms be at fault? Bad bushings... tweaked from abuse?

That sucks. I really dont want to have to go through all the extra money and trouble to fix a stupid problem like that because of crappy stock parts, haha.

Thanks Ford!!! lol.

Im not so sure thats what it is though. That just seems really sh**ty. I found out that the person that had the wheels before me did not have the problem either. I wonder if the car has been hit or abused really hard before.
