Anyone running GC/Illumina Setup on a 00 si????? I NEED HELP FROM A SUSPENSION GURU!!!!!!
Ok here's the deal. I recently had my setup installed. The shop set my ride height close to what it was on my eibach springs. I didnt take notice to see if both sides were the same height at that point. I decided the other day to drop my car again. Well I set the pirch height the same height from the bottom end of the sleeve on both sides. Its about an inch from the bottom of the sleeve. The problem is that my driver side is sitting about 1/2" higher than my passenger. I double checked again the measurements, the springs to make sure they were the same ( which they are) but to me the shock doesnt seem like its low enough. Also if Im about an inch from the bottom of the sleeve, shouldnt my car be lower than the pix below??? Someone please help. I cant figure this out.


Is this shock NOT sitting in the fork enough?

The damper is where it should be, and there is no reason to go any lower than that. You don't need to lower the car any more. You may want to check to see if the fronts are sitting on the bump stops at static ride height.
It is perfectly normal for different corners of the car to sit at different heights when all perches are set evenly.

by 1/2 inch? If I lower the driver side to be even with the passenger then I wont be able to go any lower than the pass side cuz the sleeve will be maxed out. I would expect a little difference but this seems a little bit much.
Excuse my lack of knowledge but what if he wanted to corner weight the car and the sleeve doesnt have enough adjustment to do so then wouldnt that make them pretty much useless if all four corners ride heights are so different from one to another?Thank you
I am missing the pictures showing any inequality in height, because both of the shots above appear the same to me.

I can't figure out what you're asking.
How would the sleeve not have enough adjustment to set corner weights?
The weight on each individual wheel of a car is not equal, which is a major reason the car will have a different ride height at each corner to begin with. Adjusting cross-weights to be even will cause the car to sit unevenly as well. If you set all four corners to an even ride height, the cross-weights will likely be unequal.

No they are not the same. Also if I lower the driver side the sleeve will be maxed and my car is not even though. That dont seem right to me. Plus the knuckle hits my shock.

Would the fact that the shorter sleeve and the longer spring is up front have anything to do with the drop limitation?

No. That's how it is supposed to be.

Well then I guess I have to deal with it or buy new suspension if I want to go lower?

I don't see why you would want to go any lower than that. All it does is cause problems.

well i was under the assumption I COULD if I wanted to, but based on this I guess I cant.
Make sure that you have the correct springs on all 4 corners. It might sound dumb but double check. It could be possible that you have the rear springs on the passenger side, or vice versa.
ok the wonderful guys at GC ASSURED me that the front should NOT be off bu that much and if my measurements are correct and the same on each side, then both sides should be the same height. They said I could however have a bad spring and to swap it and see if it does the same thing on the opposite side, if it does then they will gladly warranty the spring but I am going koni/gc too
my GC sit the same way, i have like a half inch of thread on the driver side, and more on the pass side, and why? cause there is more weight on the driver side, its normal for one side to be un even. if u want more threads, you should have gotten a full coilover/shock set up. i set my suspension where its even on every corner and there uneven on the sleeves, thats just how it goes, you have think about weight transfer. sleeves are not gonna be even all around
makes sense but franky from GC will disagree. He says they should be the same or damn close to it all the way around.
so if brought my car in, what would they tell me? that i installed incorrectly? our suspension is the easiest to install. if you search around, u will find NUMEROUS threads on how ppls suspension is uneven, and they tell the same thing ppl are telling you, thats just how it is. its not cause they installed incorrectly.
Oh Im not saying your wrong, Im saying they said it shouldnt. At any rate the illuminas wont let me go as low as I want to, so I am getting the koni's I should have did that from the gate but I didnt realize the konis will aloow you to go much lower.
oh i know, dont trip, i was just saying. but yea if u wanna go low get the konis and the extended top hats. since they do have the 2-3 rings aorund the shock body to adjust height as well as sleeve, im sure u have seen Dut's CTR with koni and GC with top hats

They are wrong.
Or you have some bent components under there. Was the car ever in a collision or curb hit?

Koni 8041-Sport dampers WILL NOT allow you to go any lower than you currently are. I have no idea where you got that notion. An 8041-Sport damper body is exactly the same length as an Illumina body, which is also the same length as the OE damper bodies. You will quickly find out that you'll have wasted your money.
There is something else wrong with your setup. Illuminas with Ground Control upper mounts should not be limiting you there. Perhaps something was installed improperly. What bump stops are you using?
The only way you're going to get the car lower and maintain some semblance of drivability are with the following options:
- Air bags or air cylinders, which is what you should be using for hardparking
- The much more expensive Koni 8041-RACE dampers which have shortened bodies and piston shafts, which I frankly don't recommend using with GC upper mounts
- Short fixed-stroke threaded-body dampers, as used in most of the popular aftermarket "full coilovers"
Your limit is how tolerant you are of the upper control arm hitting the shock tower over bumps. It is neither safe, nor smart, nor particularly desireable from a performance standpoint.

Ok so should I call Ground Control and tell them that everything that they told me, you said was wrong? I dont understand why they would tell me it will allow my car to sit lower. there are 3 different pirch heights in the koni which will allow the spring/sleeve to sit lower which will lower the car correct? Franky said he used both on his cars and that the konis will allow for more of a drop and more travel. Why would all that be said and you say that Ground Control is wrong? I dont get it.

That's not the point I'm making.
As I said before, it is normal for the car to sit unevenly when the spring perches are all set at equal heights on the damper body. Even stock cars sit unevenly - you just don't notice due to the wheel gap.

Not necessarily. When used with a fixed spring perch (as with stock or lowering springs), setting the circlip in a lower groove will lower the ride height, but when used with threaded coilover sleeves, they become obsolete. The position of the perch on the sleeve determines the ride height, while the position of the sleeve on the damper body determines the position of the perch on the sleeve for a given ride height.

I don't know who "Franky" is, but unless he was using the 8041-RACE Konis or 3011s or something instead of the 8041-Sports, he's full of ****.

well that sounds like a contradiction to me.
regardless of the adjustment of the pirch on the sleeve, if I move the circlamp lower on the shock its going to make the sleeve lower which which will make the pirch lower regardless of me moving it. If your saying it will with a lowering spring, how wont it with an adjustable spring? If I dont even use the sleeve and just put the "spring" on the adjustable pirch its going to lower no matter what you do.
