I'm new into the Honda game. I have a 90 si Hatch. I have looked all over the internet and it's baffling at how many people suggest different SR for the same setup.. I've seen get the shelf rates/ shelf rates are too low for a lowered setup. Get 400f/500r/ though that's a racing setup?

I recently inquired about the Koni/ GC setup from THMotorsorts. I believe I'm going to be purchasing the Stage 2 Package with 4 Koni yellows, 4 ground control coilovers, and 2 top hats. Are they trustworthy? Do I still get the lifetime warranty?

I'm not sure on what spring rates I'll be needing. It's only a DD with occasional speeding. I want to be able to slam it, or have it at 1.5 inch drop. I'm mostly looking to stay at 3 inches.

I'm wanting a 3' and a "decent" ride. I know it won't be stock, but I'd like it nice as possible.

I was thinking 450f/350r. I was also thinking of putting in a rear sway bar. Would that be necessary? If I did that, then I'd need different rear spring rates, correct?

Please no "it's going to be up to your driving habits." That doesn't help. I'm far off from any of this except for what I've said.

Thanks!

I have 350 all around (with Konis, stock top hats), and ~1 finger gap front/flush rear. They are too soft in the front. Still a lot of body roll, and the front will dive alot on a big bump, possibly hitting header/crossmember. The ride is still amazing. I wish I went 450 all around. If you want less than 1 finger gap, then go at least 450. You could go 350-400 in the rear. Nothing wrong with that. Rear sway bar is really only for performance driving. It will induce oversteer, which is not really desirable on the street. Oh, btw im running 205/45-16 rear, 205/50-16 front.

You are awesome. I love that you actually have the setup. Thanks man. I'll be ordering 450/350 probably then. I'll also be running 205/45, but on a 15.

3" drop is basically slamming the car. Even with GC tophats you're not going to have a lot of suspension travel.

If you want something that low, then you will need springrates to match. And that usually means a rough ride because you need springs with enough rate to keep you from slamming your bumpstops (or upper control arms in some cases if you are too low).

I think you'll learn quick that lowering the car around 2" will give you everything you want with those rates, except the "slammed" look. You gotta decide if you want looks or function, I suppose.

In any suspension setup you should NEVER use the same spring rate front/rear. Engine is at the front remember that lolll

Tyson

never?

front engine?

fail.

you dont know what youre talking about.

alex1321

Haha know you at least whats a spring rate?... You dont know what youre talking about.. so do you? lol seriously why would you take same spring rate at the front.

F22Master

To make the rear rotate. Learn your civic suspension setups.

alex1321

What do you mean?

Tyson

dont know you, english speak do you?

seriously, i have no idea what you said.

you choose your rates on the desired performance, ability, driver style, and application. whether the engine is up front or rear does affect the setup, it doesnt mean its always front higher than the rear, or rear always higher than the front. you can just as much end up with equal spring rates front/rear. not because equal spring rates mean anything to each other, just thats what works best, or what you want.

its not a "NEVER" and its not because the engine is in the front. if you believe those two things, you have no idea what youre talking about in setups.

alex1321

Whats wrong with my english?Yes I have some english issues but thats understandable... Im french canadian. Anyway lol explain your point why would you take same spring rate at the front?

Tyson

if you want your car to rotate (more), in other words oversteer (more), then you increase the rear rates.

if you started with 450/350 and wanted a little more rotation, you bump up the rears, and "viola" you end up with 450/450! sacre bleu!!!!

alex1321

You probly mean't Voilà! I don't get it really.. how can a car turn more with highter spring rate at rear? lol maybe you mean more stable so you can turn more?

90_EX_Civic

the rear will be stiffer, meaning less roll, meaning it will rotate more easily(break away sooner). it's almost, almost like having a bigger rear sway bar.

but with a stiffer rear end, you will over rotate/oversteer more.

there is no magic spring rate that will work all cars that will make it more stable so you can turn more. every car is different.

but then you have to also consider how the car is setup. toe, camber, caster, what type of bushings are on the car, and what type of tires you are using.

I want mostly looks. I don't mind the ride to be rough. I just want it to be the best it can be, if that makes sense.. I don't want my shocks/struts dying on me.

This is pretty much exactly the height I'd like, unless that's just stupid low?... then I'll raise it a little. Would you suggest higher spring rates for this low?

90_EX_Civic

that's pretty low, but doable. maybe up just a little, and you should be good

F22Master

450 all around should be fine at that height, just drive it smart and everything should be ok.

And alex1321, we can explain it to you a million times, but we cant understand it for you. If you want to learn more, go do some reading on race car setups. Mainly spring rates, sway bars, and alignment.

alex1321

I already knew that.

The thing I wanna say is that if you take 450 all arround you will have to put more preload on the spring to hold the front of the car at same height as rear.

Tyson

please stop.

you dont know what youre talking about.

alex1321

okay god so do you hahaha people like you shouldnt exist on forums.

90_EX_Civic

BWHAHAHAHAHAAHAHHAHAHAHAHAHAHHAHHA

there is a thing called spring height, you do know that right? and there are other factors that you are not incorporating. as in, there really isn't that much preload that you have to do.

i have Koni with ground control set up on my crx.
400 lbs all around. Its a bit too stiff for a daily.

If you wanted something more of a soft ride, a 350 front and 250 rear sounds good.
