Lopsided S13 + Tein HE... Solution?

[Legacy]

About 1.5 months ago I got my Tein HE Coilovers and installed them to the measurements given by Tein in the manual. As one would imagine, the recommended height settings were a little too high for my taste, so lowered each side down an equal length but still leaving the front a little lower than the rear by Tein recommendation.

I started to notice that the passanger-side rear was higher than the driver-side by quite a bit, maybe even an inch or more. I decided that it was probably a weight issue since I don't have back seats (don't really weight that much anyway). I'd say I lowered the passanger-side about .5", put the wheels back on just to find that the car was still a little too high on that side.

It wasn't a huge deal, but it bugs me, so today I adjusted it again since I got some new wheels and I'm getting an alignment next week... I want it just right. I lowered the passanger-side a little more and now the car seems it's about even...

BUT... when I was looking at the new wheels in the rear, I noticed that there seems to be more negative camber on the passanger-side that I've been struggling with. I'm assuming because the shock body on the passanger-side has been shortened more than the one on the driverside but I'm not positive... maybe I'm just seeing things.

Does anyone know how I can solve this problem once an for all. I just want the body to sit eveningly like it used to and not all lopsided in the rear. I could really use the help.

Thanks in advance.
