KW, FK, H&R Coilovers

[OOMPH!]

Looking for the lowering heights and where to purchase for all 3. This will help everyone out.

KW V1 (www.tunershop.com)

front 1.57 - 3.15 inch
rear 1.18 - 2.36 inch

FK?

H&R?

[OOMPH!]

C'mon batches! No one has info on FK or H&R?

You against getting the TCkline setup?

Oh and ECS Tuning sells the other two.

TC Kline's website said their coilovers drop up to two inches, that's not enough for me.

you realize the actual height is the result of spring rate, spring length, and where you weld the perches right? It really doesn't work out to be GC = 1.75", TCK = 2", etc, unless you're getting an off the shelf kit with "stock" spring rates and lengths. you could just as easily use a shorter spring with the TCK/GC kits, or weld the perch in a different place, or not use a rear adjuster, etc. etc. and get exactly the height you want.

I guess I don't see the point of an off the shelf kit?

Dude... you know they're adjustable, right? I think strut body length is more of an indicator of lowness potential than "drop." You can always lower the adjusters or get shorter springs to get lower if you really want. Of course, with shorter springs you'll hit coil bind a little earlier, but strut bottoming sets the limit on a competently set-up suspension.

I understand what you're saying....so the spring rates actually affect the height....I thought rates were based on stiffness?

What piece is the adjuster? I've seen GC's a 100 times and had them on 2 e30's.... can't picture it.

they are based on stiffness, but your car weighs something. When you put weight on the springs they compress. a softer spring compresses more than a stiffer one.. and affects ride height. plus how long the spring is, and where the perch/adjuster is mounted on the strut body.

the threaded piece that sits under the spring to raise or lower the spring height.

I have to contact GC, maybe I can buy smaller/shorter springs. My strut housings are already cut and has the GC perches welded on.

Ohhhh got it, that's the piece you use the key on.

For your technical info display in this thread, you can hand over your M3 now. :) J/k

I'd admit, I'm a bozo sometimes.....problem is I don't have the time to be as hands on with my car as I would like to.... :(

yeah you could always get 5" springs. that gives you a whole inch, it's more common to use 6" (probably what you have now). I wish I'd gone with 5" myself, i'm at the bottoms of my perches with nothing left for corner weighting. even better since you already have GC all you need are springs, which are pretty cheap.

also how much were your tubes shortened? I think 1" is typical, but depending on inserts you can do close to 2". that's only really necessary if you're running out of travel though.

I'm definitely going to call GC, that's the great thing about them.....awesome customer service! I'm not sure how much the tubes are shortened, I'm going to have to take a closer look when I check out the springs. You've been a great help, thanks bro ;)

Do you have camber plates yet? I'm having the same problem trying to get the front low right now, lol. I've got a plan though that's sure to work, so if you have questions feel free to ask.
