One side of front lower then other after rsr springs and koni struts+bushing...!?

[truwarrior]

So I took my car to a DSM shop to get some stuff done "right". Turns out now one side of my car is lower then the other and a bushing doesn't look installed right.

Any idea why one side is lower then the other? Driver side just heavier or something?

That first shock bushing looks fine, but the second was over-squeezed or installed upside down. An over-squeezed shock bushing will not let the shaft move from tangential, which will stress the shaft and cause the piston to scrape the tube, neither of which is good. Make it look like the first one ASAP.

Of course, the shock has no effect on static ride height. The listing is a 2G thing that can only be "fixed" using adjustable spring perches, such as a GC kit.

I second your opinion that second bushing is installed incorrectly. Fix that first.

I am having the exact same problem. I have tried two different types of springs, and same problem. Driver side noticeable lower than passenger.
My other friends don’t have this problem though. A friend of mine has sportlines and his spyder and its not this way, another one has prokit and his is also even.

If you find the answer, please let me know.

Questions You Will Ask That Have Been Answered A Thousand Times Already

Why does my car seem to lean to the left?

They just do. Conjecture on this subject has been wide and varied for many years, but nobody has quite been able to finger the exact reason. The best theory thus far is that the lean is caused by the engine and driver being on the left-hand side. Nobody has complained thus far that it affects any part of the ride quality of the car, although a few people have commented that the right rear of the car tends to rattle a bit more. This may be because the lower left front tends to unload the right rear suspension slightly.

(Please note that this is the original unkillable thread, and not very interesting. Resist the temptation to reopen the question.)

I haveTanabe GF210's and it's lower on the left side. When I had my Ground Controls on there, the driver's side collar was cranked up way higher than the passenger side one. I had Suspension Techniques springs on my old 1.8, and it was the same thing.

The following information would be useful in testing a theory of mine concerning listing 2Gs:

1) Does the car sit level or list to the left?

2) What are your (front) caster values?

Please note that your input would only be useful if you have both data-points and don't have adjustable spring perches. Thanks.

My car leans towards the left. If you look at the car from the front or back on a level surface, you see the car leaning toward the left. Not to mention the big 1 inch difference.

Here are my caster values
Front Left- 4.4 Degree

Front Right-3.9 Degree

Many people said our car lean to the left, but i can tell you not by this much. I had some cheap DZ springs on my car before, and the car was leveled. My friend has sportlines on his spyder and the car is level. The difference is just too much.

 

[jtmcinder]

When I first saw your caster values, I thought to myself: "self, he is listing them backwards." Then I noticed you have a 95, which is before they flipped the driver's side compression-arm bushing.

That cars with right-side-up bushings also list to the left pretty much kills my theory. Oh, well.

[Eastwood95]

did you fix the second bushing yet? Are your struts mounted correctly with the bumpstops in place?

 

[fulanititoo8198]

Could you tell me where you got those bushings?

 

[truwarrior]

Fixed the bushing, didn't do anything to the height. Bump stops are in place. DSMmotorsports

My 1g sits lower on the drivers side than the passenger after my b&g/agx's got put on.

taking this into account, what is it, exactly, that does alter the ride height and makes any of the 4 corners a different height than the rest?
People are installing just shocks and springs and getting this problem, so what causes it?
especially if everything was fine using the stock gear.

 

[jtmcinder]

I don't know what causes it. I had a theory (involving the compression-arm bushing), but it didn't survive direct contact with data. All I was trying to get across is how the amount by which the shock's shaft is extended through the top plate doesn't play a role; that fixing the bushing was something that needed to be done, but would not solve the original, listing problem.

More than half of all DSMs that I've seen list to the left. If these cars were testicles, I would now mention how sperm needs to be kept at a certain temperature and that the blood enters the scrotum on one side, such that uneven heights are required for maximum potency. But DSMs are only "the balls" in a metaphorical sense. So I must default to saying that I have no effing idea (where "effing," for once, seems quite appropriate).

^ Nice metaphor

when my suspension was installed it sat evenly on both sides, but after 4-6 months the driver side started getting lower than the passenger side also. The only thing i can think of is the weight of the driver itself wearing it down quicker... and no im not fat!!!
