Default how to adjust height of coilovers properly

i just put on my (ksports) coilovers last weekend...i locked the two rings at the top near the spring to be neutral meaning no compression on spring and no loose gap of spring (against tophat)...then i just spun the bottom part where the bolt goes across all the way up to the lowest settings until they couldnt go n e more and locked that with the bot single ring...however i still have more tread in the middle except the bot part just can't go up any higher...i put them on my car and it got lower but not as low as i want it...did i do something wrong? if so what is the proper steps to lower it some more because i know i can go lower than this...


thanks in advance

If you have no room to adjust at the bottom, then just use the top rings to compress the spring up to lower the car.

I don't know these shocks at all. However across almost all industries some shocks will have two springs seperated..... IS this the case since your talking about compressing the spring UP?

If so, one is for a pre-load height adjustment If I'm not mistaken and what he's done is completely backwards.

???? Horrible drawing of what I'm explaining....

X < Top spring which is smaller
= < Adjustment Rings
X
X < Big spring which he has loosened all the way
X


If this is correct then tighten the ring and lock ring just ABOVE the "=" section to fully compress the small top spring, the lower spring can now be used in a slightly stiffer setting and still have the ride height you want without a incredibly mis adjusted setting. From this point onward you'd need to be selecting a stiffer but shorter spring to get the job done if what I stated to do doesn't work.

Perhaps I got the whole picture of what he was describing wrong. I don't know these shocks as I stated.


Maybe a 3rd person can clear it up to make sure I haven't totally missed it.

05TurboS2k: I think you have it wrong.

Most coilovers do not have two springs (main spring and helper spring). They have a single spring that sits on a perch, that is locked by a second perch. This is for preload AND height adjustment.

Some coilovers also have a separate height adjustment where the base spins long the thread too (so the part where the bolt goes through at the bottom - that whole thing spins). That allows you to adjust height without adjusting preload. This is held in place by a single locking perch.

So, 3 perches, 2 ways to adjust, 1 spring.

oh, here is a super ascii drawing for clarity


+
---
$ <-- single big spring
$
_ <-- perch 1
- <-- perch 2 (for locking perch 1)
|
- <-- perch 3 for locking bottom part
# <-- bottom part that attaches to the car

Most Coilovers only consist of 1 spring. there are many that include the helperspring which is suppose to help eliminate the need to preload. Helpersprings also give coilovers a psuedo progressive type spring feel as well

Got it.... in offroad we sometimes use two springs to do this job for reasons that perhaps apply more strongly to longer travel systems.

Good info. The diagram works.
