why is susp. bouncy?

[Maple50175]

Well I just wanna know why it is?

Im lowered with kyb agx and neuspeed race springs


Settings at 5 in rear and 3 in front.

and it bounces like crazy. If i went any lower id prob kill my exahaust/ underside of car.

I have a feeling its the soft springs with the shocks i have.


I really might get some tenzo R coilovers or something. Because i want to be a lil lower since i still have wheel gap. Also yeah

hmm...since im not a suspension guy i can't really help you, but what do u mean bouncy, just going over potholes and etc.?

[bboygreddy]

lol my rides quite bouncy too, i have ethe same springs but gr2s not agx, that could be why

hmm IMO get higher spring rate springs or...

may sound stupid but did u install everything correctly =)

good luck!

try settin the rear to 7. this is what arrozburner is on. But the difference is that he has TEIN S-Tech springs. i think the s-tech's have a stiffer ride than the neuspeed ones. im runnin on TEIN S-Tech's and KYB GR-2's. My ride is stiff but not too stiff, just right. If almost feels close to my dad's G35. Of course the G35's suspension set up is way better. im thinkin its the springs. maybe not.

I don't really have the space or inclination to really get into the dynamics of a spring-damper system, but I'll give you the short answer. The more the shocks dampen, the less your car will bounce. The stiffer the springs you have, the stiffer the shocks you'll need to keep things from bouncing. If your car's bouncing too much, your springs are too stiff and/or your shocks are too soft. Try a higher setting. You're going to feel every bump in the road, but your car won't bounce as much.

If you find that stiffening the shocks provides too unbearable a ride, your best option is to ride on a softer spring.

You have some nce springs but shitty struts thats why. I guarantee if you change the struts youll have less problems and less bounce.

go with some koni yellow adjsutables and i bet youll be really happy I know i am.

im gunna ride in ur car the next time im with u cause thats what im riding on too. make the shocks stiffer and see if that works. itl take the long bouncing away but u will still get short bounce from bumps

[MonopolyMan]

You need it softer in the rear and stiffer in the front. Change your fronts to max and rear to 3 or so. See if that helps.

wow so kyb agx are shit? I wasnt aware of that. I thought they were good since i payed a nice chunk of change on them.


figures.

They're not shit, rated best on the market right now. http://honda-tech.com/zerothread?id=1104049

When a force is applied to a spring, a pressure wave is created. The pressure wave travels back and forth on the spring from end to end. Because nothing is transmitted with 100% effeciency, it will eventually stop oscillating back and forth, but it will be "bouncy" until it does. If you are constantly applying force to the spring as in a moving car, then it will just be bouncy all the time.

The purpose of a shock is to help damp or dissipate the force on the spring. Since the wave in the spring is travelling at a certain speed and the shock is applying a force over time, we can think of it requiring a certain distance to damp the motion completely because of the following equation:

D=Rate x Time

For a small force we need a little time and for a larger force we need more time. If the shock or the suspension reaches the end of its travel before the force is gone:

1) the shock can no longer apply a force

2) a secondary wave is created as the spring/suspension bottoms out, exacerbating the problem.

The way we solve this is to have the shock apply a greater force over the same amount of time or distance, which results in the energy from the spring being dissipated more quickly. Unfortunately, because we are dealing with larger forces, the ride will be more harsh, kinda like when you slam on the brakes VS gradually coming to a stop. You are dissipating the same amount of energy much quicker, which results in a very rapid and uncomfortable deceleration.

My experience with Neuspeed race springs though, has been that they are fairly gentle. I rode in a CD5 that had CB7 race springs on it (lower ride height and less total travel or TIME to dissipate the force) and a set of Tokico Blues. It rode just slightly harder than stock, and was by no means uncomfortable.

My guess would be either you have blown struts, they are crappy, or your settings are too soft for the spring. I can't imagine it being to soft though, with it turned up that high.

A good way to think about it is this: The spring controls the motion of the car, and the shock controls the motion of the spring. With the two mismatched, you will either have a bouncy ride, or a ride that is more harsh than it needs to be. That is why OEMs spend so much time on suspension tuning. They try to get the best compromise for ride VS handling.

Hope that helped.

Great post owenquitit,

Sadly you probably lost alot of folks. AGX are great struts for the money, Koni Yellows are better. Neuspeed Race springs with AGX are a good setup. You should not be bouncing. Make sure you installed your sup. correctly.

good post^^^

I just installed these about a month ago. brand new hmm ill try changing the settings again

[sj960]

I had the agx's and they are adimant that no one lower more than 1.5" on those struts...
I had dropzone springs with agx's and they lasted a little over a year.... currently im running h&r sport springs (1.7 f 1.5 r) and tokico illuminas.... great ride IMO
