Default xA Spring rates

Looking around for some inexpensive springs I can use for AutoX untill I can afford the $1400 Coilovers I started checking the Different Brands Spring rates, I've emailed and/or called all of the Spring companys listed as having xA Springs in the SL part review area, Follows are the Claimed spring rates and drops for all of the companys that have responded.

*Progressive Springs
** Awaiting Further Info

I called H&R springs and was told "We dont keep that information available because most people just care about how much drop, and not every company measures spring rates the same". I'm not going to go into how springs are rated but I don't think this person has a clue.




If you have any requests just PM me or post here, and I will do all the research.
I'll update this post as more companys respond to my requests for information

***Added RS*R DownSprings***
***Added FLT-A2 Spring rates ***
***Added Coilover Listing 16Feb05***
***Added Goldline Springs 15Feb05***
***Edited math on Tanabe Springs***

Great info! I just got H&R Race Springs... how do they measure spring rate anyways? Maybe I can do it and tell you so you can add to your chart.

If its linear then you can either A> have someone do it. I know the Suspension place up the street from me did it for me (Where I got the Stock numbers from) check around where you live.
B> determine how many lbs it takes to compress one spring 1 inch. (amazingly simple isn't it?)

Ashe,

Do you have time to compile a list of coilover spring rates? I'm in the market for those, and it would be really helpful. Thanks.

Does anyone know why the coilover spring rates have such dramatic differences between front and rear?

I believe it is because of two things...
First most coilovers (if not all) are designed for autosports of some type.
JDM Sports companies have a tendency for a Front end Bias (Springs Higher in front than rear)
USDM Sports companies have a tendency for rear end bias.
All of the coilovers listed are from JDM companies..
For something that makes alot more sense check out...

Springs can cause your car to act as if they are "Swaybars" i.e. the higher the spring rate the less lateral roll you notice on that end of the car... this will increase oversteer.
If thats good or bad is up to you..

Just removed my Hotchkis springs the other day in favor of the Eibach Sportline. I have to say - I could not be happier! Without any settling, they are already a half inch lower than the Hotchkis, front & rear. And, coupled with the TRD shocks & struts, the ride is awesome and far, far, far superior to the Hotchkis springs! The springs are available at the TireRack though they did not have them listed on their website (they might now). If you're interested and don't see them, just give them a call.

Well the person I spoke to didn't mention the rear being Progressive, so I may have bad info from some fool. As for the H&R they wouldn't give me any info so I couldn't help you there....

To give people a prespective on ride comfort vs suspension stiffness, let me tell a story,

About 2 weeks ago I went for a test drive on one of the new C6 corvettes. This peticular version that I drove had the higher performance suspension package. Z-something or other. Anyways, that thing road like a dream compared to my stock RS1.0. I could barely feel the highway reflector bumps that are on our California highways. Unlike on my xA RS1.0. Man, and what's funny is, a friend of mine that road in mine, but also road in a stock xB, said the xB was even STIFFER. Man, that's just wrong..

I told the guy I was most impressed with how soft the suspenion was for how well it held in the turns. He was suprised because he thought the suspension was kinda stiff, and he owns a C5 Z06. Ha..

Anyways,
point being, this is the perfect example of, going stiffer doesn't mean going faster.
