I just installed my Kei Office coilovers today, but they seem kind of bouncy, does it have something to do with the spring preload? I’ve heard that you need to set it correctly. Would allignement shops be able to do this? ---

Do they have adjustable damping? If you have them turned down to full soft the springs are doing a lot of the work. That might be the cause of your bouncyness. ---

I don’t think I preloaded them that much, and it was not like the whole car was bouncing, it was more like the shocks were blown lol, anyways, I played with the dampening and they seemed to have settled down now…all that’s left is to find a place that wll replace the top plate stud…(I snapped it when I was isntalling them :-() ---

Ok, I lowered it an inch, front and back and now the right side is sitting like half an inch higher then the left side, in the back, I measured everything twice and they are exactly the same length, now I"m thinking one of the shocks is blown, could this cause it? I thought of not getting screwed by buying from Adam at Feast, hopefully I’m just missing something. ---

Are you measuring the hight on a perfectly even surface?? Even a slight shift in the pavement or wherever your car is sitting while you’re measuring will make noticeable a difference. ---

I measured from the top plate to the top of the bottom mount while the car was in the air, everything was even, everything was perfect. NBut when I drop the car back down, and I looked at the car at different spots, all of them as flat as I can find, I measured to the top of the fender, one side was a half-inch higher, but you can actually see it when you look at the back of the car. ---

If one of the shocks is blown, would it sit lower then the others? Also, if one shock is set at the softest setting and the other at the hardest, would one sit lower then the other?? Thx. ---

If shock is blown it wont really affect the car as it sits, only when driving. The springs are what affect the ride height. Correct me if I am wrong guys. It is possible that the car does not carry the same weight on all four corners. It would always be best if you could scale the car to see. 4-point scale. If someone hear could explain how to properly set spring preload, it may help allot of people. CVM07 ---

i had almost no preload on my coilovers at the beginning of the season, they felt kinda ghey adding preload is simply threading the collar under the spring higher to put additional load on the spring. set your coilover to equal height with almost no preload = spring perch threaded just to where the spring will not move around. then maybe add a half inch of pre-load and try it out ---

You cant just use the same measurement for every corner when lowering the car. It is common occurence that one coilover may need to be set lower than the other one to make the car sit at the same ride height. ---

Ok, but can I measure them all the same for the preload? And also, for the height, so I should just meaure the car on the ground to determine the ride height and do all 4 corners seperate? Thx for the help guys.
