Rear wheel alignment issues... HELP!

[Rambo305kid]

I searched the forums and tried to reach out to many people who own this car but no luck. The issue is my rear wheel alignment is off. My left rear driver side pokes out further then the rear passenger side. By almost 1/2 and inch. I’ve replace my coil overs to Bc extreme low, I’ve also replace lower control arms, trailing arms, and toe arms to see if any of this would change this. I’ve gotten 2 wheel alignments and mechanics can not seem to figure out why my alignment pokes more on one side then the other in the rear. I’ve also check the wheel fitment which are the exact same work meister s1r 18x11 offset are +15, tires are the same. What could it be? 🤔 take my word it’s very noticeable pics don’t really show it but when I lower the car even more it shows.

Body kit tolerance?

I wouldn't be surprised.

Measure from the wheels to equivalent reference points on the car's original sheet metal.

What is rear alignment spec?
Have you tried swapping right and left wheel to see if issue stays or follows the wheel?
Are your coilovers setup to the same exact settings?
Are you running spacers?

Hello Rambo305kid and welcome to our forum -

I suggest you go to a different alignment shop, explain your concern and have them fix it.

Your body kit sucks.
You can clearly see it's bowing out where it's not held in by the bolts.

No difference underneath the fenders still the same issue. I get my fenders are bowed but to be uneven an entire 1/2 inch is not fenders. The specs of the alignment are pretty straight all around. Rears have 2 degree of camber and there’s a very minuscule difference in toe for the rears .3 difference. Is there any type of adjust in the subrame that could be made? I do have stock up control arms so I’m not sure if bushings could be a factor in terms of the poke difference....

one fender looks far more bowed than the other though... which would account for the 1/2 difference. I would argue the likelihood of the suspension being off would be far less than a wide-body fender being off. Especially considering you have been replacing suspension parts and alignment is checking out.

Also, .3 is a pretty large difference in toe.

this, especially the last part.

You need to measure from the inside bottom rim of each wheel to a hard, non movable part of the permanent body structure thats the same on each side. Not a control arm etc, but a permanent mount. If that number is off by more than a millimeter or two AND your camber and toe are exactly the same (complex math follows if the camber and toe are different) then something might be tweaked

This is blunt, but probably true if you're not the original owner. 1/2in off is is possible, that's only 1/4in off in the kit plus 1/4in from damage. Get the right shop to "fix" the damage and keep the title clean, and voila, damaged car with no marks. If there's damage pushing a hub out of place your static alignment can look fine, but the suspension will act incorrectly under dynamic loads. Any chance you've had recent track time to feel out odd oscillations during cornering?

I test drove a Fiesta ST that was damaged like this. The bumper line was uneven and sprayed over on one side. It had a slight oscillation taking long sweepers even at public road speeds. A consistent indicator for damage is if there's a line for "One tire/wheel replaced" on the title just before or after a sale, and it's pretty much confirmed if there are panel gap inconsistencies to go with it.

I'm also a pessimist. This could all be bad kit fitment if it's a cheap one. I'm honestly rooting for that, unreported frame damage sucks.
