Just got done installing my AGX/ road magnet setup on my 93 b13. Besides the usual clunk, squeak problems( I have plenty ideas to fix) the rear end has about 1/2 inch height difference between the two sides. I have made sure the springs are seated right, and there is still the difference. I used the rubber hose method on both sides, and ended up taking it off on the drivers side, reducing the difference down to 1/4 inch. Is my rear sway bar possibly the culprit? Has anyone else had this problem?
btw, I've searched and searched on this forum and come up blank.
Besides a diff. spring rate, two front springs are also taller. The rears were both the same hieght when I set them side by side. 3 of the four sides look perfect, but the drivers side has too much of a rake to it. I know the springs are in the right spot. when the car sits on the ground, looking between the tire, and quarter panel, you can see one spring is compressed more than the other. That's why I belive maybe something is keeping that side from going too low? It's not noticeable to everybody, but it's phreakin drivn me crazy!
and after:
this is the good side. the rear on the other side sits just a bit higher. there is already a good amount of rake to it, just imagine another half an inch. I know I didn't mix up the fronts with the rears, or the nose would be sitting on the ground, because the rear springs were considerably shorter than the fronts.
I forgot to mention ruling out the struts as the problem. I installed the springs on the stock struts to get a good look, and noticed the difference back then. I figured the old or new or mixed up stockers were playing tricks on me. But the new agx's are treating it the same.
sorry about the long thread, but it's not very often I am at a loss like this. please help!
i'd say drive around with it for a week, and try to have 4 people in the car. maybe the springs will slowly shift into place???
I second that. Maybe one of the springs isn't seated quite right.
take a picture of the other side too just for people to see what you are talking about.

I still second guess myself on my spring set up all the time.They all looked the same length to me so I installed the thinner looking ones in the rear.After about a week I got out the trusty dial calipers and measured the spring thickness and I had them set up right.The only thing that bugs me is my front sits higher than the rear.But I have taken a lot of weight off the front end.
They will settle in after a week of driving so give that a shot first.
the front does not sit higher. On the B13s, the rear fender design looks lower then the front. It touches on that in shawnBs suspension thread and a couple others out there.
I only drive it a few times a week, so it might take longer. I've got a few buds coming over tonight, and I'll take them all for a little joyride on some twisties. That is if the roads dry up. I appreciate all the input, and I'll give it some time before I freak out.
btw, don't think for a second I regret my road magnet decision. Thanks to robchaos. These springs are great. Paired with the agx's I can't imagine a better ride. I got rid of the clunks and sqeaks, and the car only has 80,000 miles so it feels solid as hell.
I think I might start a thread asking for before and after pics of the rm gen 2 setup, and everyone's opinion. later......
Give it a few days. I remember when I first got the springs on my car sometimes I would look at it for a minute and think to myself that it seemed a little uneven, but right now I still have the original test set from the round 1 GB on my car (yeah haha I'm lazy.) and they have held up outstandingly and the drop still looks perfect. Mind you that this is on a test set (unshotpeened and not powdercoated.)

I have read that and can tell the difference but for some reason it just mentally screws with me.My mild OCD makes me think I screwed something up.
usually I sit back and think it looks great, but I sometimes wonder if I did something wrong. Not much different than the mother of my two kids Just got back from a pretty fun ride, pulled some G's with a bunch of weight in the back. We'll see. Everyones here, time to put down the keys, and start drinkin. Thanks you guys! toast

may i ask you what was causing your squeaks and clunks? my agx/rm springs are driving me crazy over bumps but only in the rear on my b14.
OK, a couple of things come to mind; when you verified the springs were seated right, we you refering to just being centered in the perches, or did you also verify that the end of the spring that sits in the lower perch is rotated fully so the end of the coil comes in contact with the detent on the perch (if someone is familiar with this setup, and that detail does not apply, please call BS and correct me. I don't want misinformation out there).
When you did the work on the suspension, perchance did you have the suspension mount points (and/or swaybar links) loosened on one side with the wheels of the other touching the ground? The OEM rubber mounts are not mobile in the same way as the polyurethane ones, and you must have the car down on all four wheels prior to torquing to spec, otherwise you will preload, and potentially jack one side of the car.
You mentioned the swaybar. You might check both the back and front for binding. One sure fire way to check that the swaybars are not responsible for the preload, is to detach them at both end links. Then, you are relying solely on the springs to support the weight of the vehicle (after giving the suspension a bit of a bounce to remove any residual friction from the struts, etc).
Hope we can sort this for you!
