Need Advice: Rear chassis sits much lower on pass. side (Coilovers)

I've been meaning to ask this question for a while. My car sits over an inch lower on the rear passenger side when my spring adjusters are set to the same height. In order to make the rear of the car evenly stanced, I need to set the passenger side adjuster to almost the highest collar setting, while the drivers side is where I want it at almost the lowest setting. What could be the problem? I know that many times one side will tend to sit a bit lower, but over an inch different doesn't seem right. Nothing to do with the springs or adjusters, I've measure both and they're equal.

measure on different surfaces to see if it's the road. Keep front wheels straight. The battery is back there if you have weak springs that may be the difference.

I've tried that many times unfortunately. I also originally thought it might be the battery but I already have a lighter battery there. Gotta also keep in mind that the exhaust is on the other side to balance it out.

Alright, question and answer time!

Are the correct springs in the proper places and installed correctly?
Does your setup have compression, rebound, damping, and/or preload settings?
Swap the springs in the rear, does the issue move with the springs?

Yup that's how mine is! Funny thing is when I tested the oem size springs they provided without adjusters, everything sat even at stock height

Everything is perfect, I've re checked many times including swapping sides. The Coilovers are compression adjustable and incorporate adjustable shock bodies, all are set evenly.
