Just installed Ground Controls... Ride height isn't even
I just installed GC with Koni yellows on my 2000 GSR. I measured the space between the bottom of the sleeve and what the spring rests on. I set it at 2" both sides but when I put my car down, the passenger's side was about 3/4" higher between the fender and tire. I lowered that side to even it out and have driven it for about a week now.
Brand new OEM hardware was installed including bushings, bump stops, and dust covers all which were trimmed to the specs for the GC / Koni yellow setup. Matching tires and tire pressure.
I also installed the Skunk2 camber kit and set the adjustment the same for both sides. I havn't done an aligment yet.
Anyone know why this is?

Thats what I'm going to do if there isn't any other cause for it. I just dont want the get it aligned and afterwords not have the ride height I want.
I see you're new here. This is a forum for car related questions. I'm trying to prevent wasted $75 on an alignment. Don't post unless you have something constructive to say.

Anyone had a problem like this before?

Well, as I am sure you know the alignment doesn't affect ride height, unless you have a serious camber problem, ie loose upper ball joint, or lower control arm, or bent spindle.
I remember with my old Skunk2's (same as ground control) that some times the spring would not sit in the perch straight, causing the ride height to be un even. I just used a piece of string, and held the spring up straight, then lowered the car, and voila! It was the same height.

As far as I could tell it was sitting in the perch straight. I will check again to make sure. Its just hard to see once its lowered. Good tip though with the string
in an ideal world it should be the same on all sides, but we live in a realistic world..
there are other factors that can attribute to uneven ride height... engine placement, whats in the trunk, where a driver sits, etc... even struts dont wear evenly right??
dont worry about it, just adjust so that the heights are the same..

I have the same set-up except its for my DA9. I didn't set the perches on the sleeves in the same place for all the sides.. You'd have to make one side lower/higher... but this counts to as front and rear, not your pass. and driver your experiencing. Maybe you set your perches the wrong way? Or the stock spring perch you still have on the shock. koni hasa snap ring where the sleeve is suppose to rest on. hope that shed some light... let us know what happens
YOU'RE SCREWED!!! jk... i'd imagine it probably just is what it is... which is why coilovers are adjustable... maybe try corner weighing your car, see how she balances out... another possibility... did you get the new setup new? or used?? i don't know who has a spring pressure tester that big, but if someone does, you could have all the springs tested to make sure you don't have a dud... possibly a blown strut... again, you know the condition of your equipment better than i do...
did you make sure all 4 metal tophats are on the strut rods (at the area where the diameter increases, this piece sits right up under the strut tower)? so you don't have a rod going up through the hood etc...
or you have two heavier springs on one side of the car (instead of front/rear)
just a few thoughts/suggestions... i'd imagine a corner weight test and a spring test would uncover your answer though. otherwise you have a blown or short strut, or the car has wreck damage (which is unlikely)

I'm 90% sure that you mixed up the springs. The springs will have the same height, that's why your measurements to the perches were the same when they are not loaded. But when loaded, the side with softer spring will sink.
I had the same issue with my Skunk2 ProS coilovers. Turned out I mixed up the springs for front and rear. Had to go back to the box to find out that the numbers on the springs and what their spring rates are.
Did you notice one side was a little bit harder to adjust than the other?

i see this happen from time to time and i people blame that driverside is heavier than passenger side. I would have gotten coilovers. Lower the perch on the passenger
i had the same problem with my crx and skunk2 pro- s also. lol funny it could have been mixed up springs lol.. too bad i sold the car or i could find out.. your camber could be a problem.. get a life time alignment form Firestone or something then after u get it aligned, your can still adjust and get another alignment

All 4 corners of the car have different corner weights. When I had GC's, I adjusted them to the car would sit level. I didn't pay attention to the actual position of the perch on the sleeve. In the end, all 4 spring perches were at different heights to get the car leveled out. It's just a trial and error process. Keep repeating until you get it right.
Also, once you get the ride height finalized, you should reset your bushings by jacking up the car, loosening the bolts at all bushings on the lower control arms, jack up each corner suspension (as if it's loaded on the ground) and then tighten the bolts to spec. This will prevent the bushings from tearing with the control arms at a different position than they were at stock ride height.
And I personally would have skipped the camber kit, since toe wears tires, not camber. Negative camber is good for handling. Please do not set the camber kit for straight up 0 camber. When you get the car aligned to set the toe, that's what keeps the tires wearing evenly. Just remember that your tires will wear at an accelerated rate until you get it aligned, regardless of how your camber kit is set. And also remember that toe changes any time ride height changes. If you adjust your ride height later, you must get it aligned again, or the tires will start to wear unevenly again

I'm pretty sure the perches are set the right way but I'll check in a couple days when its a little warmer. I'll check the snap ring theory as well. I did the suspension with another guy and we were both double checking everything.
This is a brand new setup, everything new. I checked the springs and made sure the model numbers lined up for front and back. Both sides when on the same. Tophats look good.
I'll give that a shot once it's all said and done. I only got the camber kit because the upper control arm on that side was messed up. That was the only damage that I saw to the suspension but I will double check again. The car was slammed when I got it.
I'm sure that is it what it is. I'll double check everything listed and get it corner balanced and aligned and let you guys know what happens. Thanks alot for all the ideas.
And thanks for the replies in both of my posts Patrick. You're always very helpful.

It's not the snap rings or anything like that. There is nothing wrong with anything on your suspension. You just have to adjust each corner individually to get it to the height you want. You'll never have even height if the perches are all at the same height on both sides.

this thread makes me want to go through my suspension and freshen everything up... somethin to do i guess
Double check to make sure you've got all the springs in their correct places. A buddy of mine could never get his car to sit level and he had put a rear spring in the front and vise versa in the rear.
