Quoting TurboTony:
Can you describe the spacer install? I have the same issue with the AGX/ProKit install on my GGSX as you can see:
Front (after engine install)
And rear:
I don't mind the height of the rear so much, I just don't like the differential. If one end was going to be higher I'd be happier with the rear being higher.
What I did as a simple quick easy fix for the difference in springs between the 1g DSM drop springs and GVR4 springs is took a spare rubber upper spring absorber (for lack of a better term, the rubber deal the spring rides in at the top strut mount in the rear), basically I stacked two of them in there instead of just one as there normally would. I mentioned it spaced it about 1", but more accurately, I think I gained about 3/4" which was perfect. The handling seems improved as well, and I don't seem to be bottoming out anymore with rear passengers. I've had this setup for almost a year with no issues whatsoever so far.
Keep in mind, I only have GR-2's and not AGX's, so your setup may differ, but you should be able to achieve similar results.

I would double check the install, and make sure everything is mounted right. From what you describe, it seems to be excessively leaning to the left. I'm assuming you took it for a drive after the spring change, if not, you need to do so, provided everything is tightened down and safe, springs do need an opportunity to seat/settle. I notice when I take mine off jackstands, it seems to sit higher than it normally would after dropping it to the ground, a nice drive puts it back where it should be.
With that said, I noticed with mine and most other GVR4's and DSM's, they all seem to lean to the driver's side slightly for some reason. I attribute it the the weight difference between the motor (being on the driver's side, of course), and a bigger part of the fuel tank being towards that side as well (to clear the muffler). With even stock springs, I can see how it would lean to the DS slightly with that extra weight, but two fingers to no fingers seems a bit extreme.
