Simple coilover adjument question
 

Sounds like a dumb question but i've never had coilovers before until I bought this 99GSX with coilovers already on it. I want to lower the car about .75". To save me some jack time, do i unscrew the threaded coil adjuster towards the ground or in towards the top of the car?

Also, is it generally a 1:1 ratio meaning if you unscrew/screw it say 1", that's the equivalence of raising/lowering it 1"?

Thanks for the help.

Away from car, and yes as far as I know.

Re: Simple coilover adjument question
 

If you screw the perch down 1", your car will sit 1" lower.

The ride also get a little softer as you raise the car. I've got a 98 Accord Coupe that's actually liveable now that I raised it .75".

Re: Simple coilover adjument question
 

Keep in mind that all depends on the shocks (I'm assuming the Accord has stock shocks still?). My Talon actually rode nicer with AGX's and GroundControl's when it was down ~2" from stock. Then I took it down even further and the ride became not quite as nice.....but I left it low :)

Thanks for the help guys. I might just go 1/2" to maybe 3/4" and see what it looks like. I gotta jack it up again when get another guy over to help me bleed the brakes so i make further adjustments at that time if needed..

Thanks.

Went to lower the rear supspension last night and i noticed the coilover adjuster was down as far as it would go. That sucks! I probably have 1.5" or so between tire and fender lip. I really wanted about .75".

I have Tokico Illumina 5-way gas shocks and Eibach springs. I "THINK" they are the pro-kits. They say 22/99 on them. I don't know what that means. I measured the free uncompressed length of the spring and it was exactly 7"

So if i want to lower it more do i just need to change the spring to a shorter one? I have all kinds of adjustmen room in the front. It's just the back which is odd.

Thanks.

Re: Simple coilover adjument question
 

What brand of coilovers are they? You can't have Pro-Kits with coilover adjustments, the springs sit totally different on the perches vs. on the shock. What color(s) are the springs and perches?

Re: Simple coilover adjument question
 

I'm not sure what the brand is of the coil over(I just emailed the guy i bought it from to find out). The threaded part is an anodized red. The adjuster part is anodized gold. The Tokico Illuminas are White with red lettering. I'll have to check the spring color at lunch when i go home but they are definately Eibach. Says right on them.

What's a perch?

Thanks.

Re: Simple coilover adjument question
 

Based on those colors the coilovers sound like GroundControls to me. The springs should be red with white lettering/numbering. GC coilovers do use linear rate Eibach springs, but they are nowhere near similar to Pro-Kits. Write down the spring part numbers and give GC a call; they can look up the spring and tell how how far the car should be able to go down, and if needed, they can recomend a new spring for you based on your needs.

A perch is the piece that threads up and down that the spring sits on. They have a little locking hex set-screw correct?

Re: Simple coilover adjument question
 

Yes, it had 1 locking hex head set screw. I will write down what it says at lunch maybe even take a picture of it. I could almost swear it says in white lettering Eibach 22/99 but i will double check.

Thanks.

Re: Simple coilover adjument question
 

Alright, call GC and tell them that and possibly order new springs.

Re: Simple coilover adjument question
 

Thanks i will post what they say...

PS- I went out on ebay and found some GC coilovers and they look identical to what i have. Thanks for steering me in the right direction.

Re: Simple coilover adjument question
 

Ok, just got back from lunch. Yes, there were more number on the coils. They are 0700-250-0400. 0700 is the length, 250 is the inside dia. -0400 is the spring rate. I called GC and they recommended to go with a 0600-250-0450 for the back. The rates, etc.. were pretty similar.

The springs are $59each. But i'm sure i will have to get it realigned after all this, correct?? That will be the disadvantage of the desired look.

Re: Simple coilover adjument question
 

Everytime you adjust your ride-height the car *should* be aligned for proper drivability and handling. Purchase a lifetime alignment from Firestone or whoever you prefer, I generally would get my car aligned twice a year.

Re: Simple coilover adjument question
 

I just placed an order for the 0600-250-0450. That should drop it up to an inch. I will get it aligned. On my old GST i had purchased the Specialty Products camber kit. Decent. I actually used a carpenters level and placed it on the wheel and got the alignment close. Went i took it in, they hardly had to adjust anything. Cool huh? Do you recommend or have experience with any other kits? RRE sells some i know.

Re: Simple coilover adjument question
 

I never used anything when I dropped my car 3", 1G FWD's are cool like that (although I did have a lot of toe in the rear, but not so much where it became a problem). I'm not sure how the 2G GSX's react to being lowered, but I know those 2G FWD's get a ton of camber. You also might want to cut your bumpstops in half to help prevent bouncing around a hard corner, leave some on there though to avoid destroying your shock.
