well hey i have some lowring springs that are used and they ride decent and they are about the same rate as GC coilovers email me about them i will sell them for cheap they costed 225 new. the springs will make you car almost yuck 17's in the front and give about an inch and a half of extra space below the wheel well
my email adress as dirtydan463@aol.com
they definately will make your car handle better and paired with agx they would be an excellent setup, they make a good handling spring setup with illuminati struts

race spings are a 2.25in drop, sports are 1.5in drop, race springs in MI is a bad thing, shitty roads and even shittyer weather

I don't think they are limited editions. how would I know? I didn't see anything on the spring

OK, in on of the previous posts somebody said that the AGX's were not valved to handle most spring rates, and now somebody says that the springs are too soft. So if that's the case then the AGX's should be fine for this spring rate.

All I can say is that the ride is too stiff, I don't understand how my shock UNDERDAMPENING would cause my car to feel stiff.

I still think the problem is the linear type springs. It totally makes sense to me that a linear type spring would feel harsh when you go over a dip fast enough and the progressive would give more cushion.

An underdamped suspension feels stiff because it compresses/extends quickly. Loads are transmitted to the chassis faster which feels rougher.

If the rate of a progressive spring is 300# (for example) before coil bind, then they will feel softer than a 300# linear on small bumps. For big bumps the pro spring will be more compressed in its final state, where it is more likely to bottom out. This will feel stiffer than a linear spring. Otherwise you won't be able to tell the difference between them.

Default Re: progressive springs vs. linear (GSpeedR)

so you are saying that my ride will feel more stiff with STOCK shocks than it would with my AGX's on 4??? I don't understand that concept at all. I thought the whole point of a shock was to control the rebounding/bouncing effect that you get from the springs.

underdamped = bouncy ride / blown shocks
overdamped = stiff ride / stiff shocks

Right???

what research has suggested you need to change out your progressive GC springs for different progressive springs ?

how low is your car anyway ?

i have eihbachs and the agx shocks and my ride is fine. by the way did u check the shocks to see if they were leaking maybe ther are leaking and causing your car to bounce like a basketball. just a thought

Default Re: progressive springs vs. linear (2000GSRT)

Way too big of a generalization.

The shocks do control the springs motion with a resistive force proportional to the spring velocity. Heavily overdamped will actually feel much less responsive and softer since spring motion is very slow. An underdamped system allows rapid and possibly cyclic spring movement (if they're blown). Perfectly damped is between the two and "damps out" spring velocity fastest.

Too much of either is bad.

well the ground controls are linear, i think that's what you meant to say...

But that's a damn good question, I haven't really found any solid evidence saying that progressive springs give you a less harsh ride than linear. I did read something on this website under the spoon progressive springs that said that progressive springs were less harsh than the linear coilover types: http://www.aj-racing.com/spoon....html

my car has about a two finger gap all the way around

I'm starting to realize that maybe it isn't the ground controls that are giving me the harsh ride though. I think it's the shocks just being stiff and not letting the car glide over the dips like the stock ones do.

However, since I already have my shocks on the lowest setting there is nothing I can really do about it. I guess that's the price you have to pay for lowering your car....the ride is gonna be ruff.

AGX at setting 1 are equally stiff as stock

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">
The AGX products have the following approximate damping force values. When adjusted, both rebound and compression damping forces change.

Setting #: Relative Value
1 - Same as Factory 100 (same as OEM)
2 - Same as GR2 115 (15% firmer than Factory)
3 - 50% firmer #2 172 (72% firmer than Factory)
4 - 30% firmer #3 223 (123% firmer than Factory)

well if the shocks are the same as stock then I guess it is the ground controls not giving me the ride I want.

Any suggestions on what to get?

I'm really leaning toward going back to the stock springs and then cutting them to get my car to the desired height

What are the GC spring rates? Increase the shock firmness, and see how it feels.

If you want. You'll be back here asking why your ride is stiffer than it was before. Answer: the stock springrate is insufficient to keep the shocks off the bumpstops at a lowered height.

The use of the word "stiffness" when describing shock settings is definitely confusing some.

No, it is still the shocks and this proves it.

The stock shocks are valve SPECIFICALLY for the stock ride height and spring rates. If you raise the spring rates or lower the car, the shocks are no longer operating in their desired range and are under-dampening.

You are running 380 lb/in 250 lb/in on what would be best for 212 lb/in 117 lb/in.

Are those the spring rates you are reffering to? cuz on my springs it says 200 in front and 180 in back.

So you have custom rate, lighter than stock front springs?

Because the ground controls for integras are 380/250

why dont u just try rasing your car up 1" all the way around, get a garden hose and rinse out all the sand and rocks off the threads.

When you raise your car, you will notice a big difference and find out its not the linear springs causing your woes.

From my understanding, 200/180 markings are the metric conversions for 380/250.
