Has anyone have issues with adjusting ride height (measured from the frame) with coilovers in the rear?

The left rear compresses significantly more that the right rear. I have the left rear adjusted all the way up, and the right rear almost all the way down. I don't see (under or in the car) where this weight is coming from in the left rear to make it that uneven.

I went through the preliminaries; disconnected the sway bar and struts, and re-installed my Eibachs. The same issue was still present with the Eibachs, the difference side to side was almost exact.

 

installed my progress rear sway bar today, noticed something similar going on with my base fit... will have to look up on how to make adjustments

 

Left hand drive GE8 seem to have a strong left side weight bias, something like 52% left weight distribution from the forums.

With my setup, 5kgf/mm front to 2.4kgf/mm rear spring rate, I've had to set my left front and rear ride height 10mm higher then the right front/rear for the car to sit level with me sitting in it. (The Fit's front strut springs has a motion ratio of 1, and the rear is ~0.8, so the actual spring perch height setting is 10mm higher LF, 8mm higher LR)

I had the same problem running TEIN 2kgf/mm rear springs where, after the springs had some time to settle and sag, the spring perch was running out of threads on the left hand side and the car was still sitting too low. Swapped them out with the stiffer Bilstein Springs for more more usable adjustment range.

 

Also if only the LR is sitting too low, you can try lowering the RF, that should help raise the LR, unless the car has significant flex. (Assuming you're on level ground)
