Got an '01 GTS that I run on the road course quite a bit. I just saw a pic of my car taking a hard right hander and my right wheels were off the ground. Not good ... seems to be time to stiffen up that suspension a bit. I've also been told that my stock Koni's are adjustable ... this is good and I plan to do that, but while I've got the springs off to make that adjustment I'd like to replace them with something stiffer. I honestly don't care about street comfort. Been in Vipers since '95 and I apparently have no kidneys because it's never bothered me a bit. I do NOT want lowering springs, just stiffer at stock ride height to work with the stock Konis. I've had a lowered GTS and I never want to go there again.

I'd stay with about a 200#/inch split between the front and rear. I run 600/800# springs, which is on the firm side for street driving. I've thought about bumping the rears another 50#, but not dissatisfied enough to spend the bucks. Eibach and Hyperco are the manufacturers of choice.

If SW lowered your silver car, it's no wonder you were unhappy. He tends to go a bit radical on the drop. 1/4" at the shock will net you about 3/4" at the side sill. I have an extra set of stockers at the house with reduced height spring retainers if you're interested.

Thanks Dean. I'm really determined to stay with stock ride height. SW did drop the silver car and I felt it was undriveable on the street. I then went back and had him raise it up to about halfway between that and stock and it was still a pain in the ass. Scraped everywhere I went, could hardly get over the transition into my parking garage. I ended up hating the impracticality of the car on the street. I know it'd be faster at the track if I lowered it a bit, I'm just not willing to endure the scraping headaches anymore.

Do you know if those Eibach and Hyperco springs (600/800#) come in stock height configuration? Who would you buy from?

 

[Toby]

GTS Dean has it about right.

Rear springs need to be stiffer than the front on these cars it seems.

600/800 is a bit stiff for the street though (my 2 cents) as you might experience tire lift on high speed turns if you hit any type of bumps.

This rate along with setting the shocks to full stiff might have you loosing control on rough roads.

GTS Dean...you experience this at all?


I would recommend reading this book...it is really good.


you can buy at amazon

You can buy hypercoil springs in almost any rate in free lengths. You have to then cut them to height needed for the proper ride height or corner weight if you do not have threaded collars. You can also install a threaded collar on your stock shocks with a simple bit of work. I have done this and it makes for a nice handling car when finished.

Best part is that you can set your car up for street and race without having to alter or comprimise.

I currently have Eibachs in my car and absolutely HATE THEM. The ride is bouncy and the car handles much worse than it did before. My next upgrade is to eighty six the stock shocks and springs and go with some Penskes or Motons with the Hypercoil springs. Has anyone ever tried the Roe Suspension?

Stiffer springs will be faster if you can handle it

Quit ragging on the kid, Jason. Did you happen to notice that she made no spelling errors in that incomplete sentence?


Toby,

As long as you don't under- or over-damp your suspension, spring choice is pretty liberal. What you do need to be concerned with is wet weather behavior. One definitely needs good compliance so as not to upset the tire contact patches. 600/800 may be a little bit stiff for stock Konis, but even lowered, they actually help keep you from bottoming out as frequently through dips. Dave is right about the adjustable spring perch kit - quite inexpensive and allows easy adjustment of ride height and damping.

Well good point Dean!! /images/graemlins/supergrin.gif Spell check maybe?

I hear Adeldork is a huge fan of the Roe suspension. :rofl:

:slap:

 

[Jasonmiddletn]

How about the Moton set-up? I know Jeff Ellison has it on his RT and loves it.

 

[SEric]

What does a decent set of springs cost and where should I buy them?

 

[GTS Dean]

Truechoice sells Eibachs for the Viper at just under $300.

You guys spend more money looking for name brands... Buy a set of Hypercoils for about $50.00 each and be happy. Some of the rates you need can actually be cheaper. I once bought a set of TEIN coils for less than $20.00 each and they are the highest line of imports you can get.

Here are the parts you need to get and you will be surprised at the price!! Most pieces cost less than $20.00 individually.

Here is the threaded coil-over body... it costs $12.00

Here is the upper retainer. Guess how much.... $15.10 each.

Wait... these break the bank at $25.00 each.

Then lastly you can add these babies to move your weight around.

Spring selections are simple in 25# increments. You can even add progressive rate 3" or 4" coils that will make your car ride smooth but still handle the turns.

Let me know if anyone wants a setup built right. Think about it... for less than $400.00 you can build a complete coil-over system for your car. Truechoice can also revalve your factory Konis and build them for any rate spring you choose. Why WASTE money on high dollar Moton remotes when most of you guys wouldn't know the difference...??? I will put money that you couldn't tell the difference between a properly setup stock suspension and someone who has spent more money on High end name parts.

I am getting ready to install Eibachs with higher rate and about 1 inch lowering on a Gen I. Am I making a mistake? Note use is limited as the SRT is getting all the street driving of late.

So I'm a dummy and didn't quite understand what you're showing here. Are those components pictured an adjustable height spring perch setup? Is that required to fit the Hypercoils onto a stock shock or is it a separate feature? It looks like an interesting thing to have, no doubt about it.

Now a question about the Hypercoils. It sounds like you have to cut those to fit your car and that makes me a bit queasey. I don't like the idea of cutting a spring. It ought to have a flat coil at each end to bear correctly against the spring perch. I know a lot of people do cut them, but I can't imagine that's the right thing to do. Can you get Hypercoils that are already formed to fit the Viper with the flattened coil at each end?
