91 trailing arms

[Bdub]

So, I'm still having my problem where the LR of my car is sitting lower than the RR. I let it go, because it wasn't really affecting much.
But now that I've put on my 16" wheels, the car is insanely low. Like, go over a bump and hit the inner fender.
It has new springs, the struts are fine, and nothing appears visually "bent".
I've had the car aligned twice, and they never had an issue with that side. I'm thinking of replacing the trailing arms to see if it makes a difference.
I'm not particularly looking for an upgrade, just a solution to this problem! So, my question is, other than the 91 Legacy trailing arms, what others can I use? Will Impreza sedan ones work?
I've yet to find a definitive answer.

So just what I thought, I'd probably need to find updated endlinks and swaybar because my 91 wouldn't work with anything else.
That sucks.

Are you sure everything is put together correctly? Maybe the spring isn't seated correctly in the strut. Do the strut part numbers match up? Maybe the spring perch sits differently on each side.

what type of struts are you using?
what springs?
what size tire on your 16"?

i got agx with whiteline springs on standard sized 15" tires and though it's a bit saggy, i haven't hit the back inner fender.

Just oem 04 wrx springs on gr2's. It didn't drop the car anymore than .5", so I know that isn't the issue. The shocks rebound just fine, and although the tires are rather wide 220 I believe, the RR doesn't have any sort of rubbing issue.

To get a nice visual before I add some pics here, on the RR I can fit my fingers between the fender and tire just fine, but on the LR it's a pretty tight squeeze to get my fingers between them.
I know I could just roll the fenders, but the car is still going to be sitting awkward.
I've ordered some saggy butt shims to just pick it up in the back for now until I figure out what's actually wrong.

Did it sit funny before you put the STI springs in?

[Bdub]

Yep. My original thought was a shot spring, they were pretty rusted up.
I got under it again yesterday and quadruple checked everything. It all seems to be in order.

After looking at it long and hard, I have realized that the car has had bodywork on that side, and it looks like the panel was replaced lower than the one on the right. I knew it had work done to it, I can tell by the less than subpar work on the paint. Never even thought to measure the difference of the fenders.
So, I'm guessing that is my problem right there.

I'll stick with the butt shims.
I ordered 1/2" thick puppies so it'll pick it up enough so it clears the fenders without issue.
