Hi All,
Does anyone make lowering springs for the Evo that are not progressively wound? Please don't bother telling me about coilovers, as that is not my question.
Cheers,

 

H&R springs are linear rate. They go for $329. They will be listed under EVO VII

 

Thanks Option2,
I thought they were progressive and so did the guys at Vivid. Will check again.
Cheers,

 

wtz, could you post the rates when you get them? How much they lower the car etc. Hopefully they are linear and not so stiff that they require shocks. Thanks

 

eibach makes lowering springs as well..
i bought them for my VII from coordsport.com in london...
cost is 220 pounds

 

Eibach is a progressive winding, but thanks for posting.
Cheers,

 

Saw a picture of the H&R springs for the Evo VII. They are clearly progressively wound.
Still searching...

 

Have you called Road Race Engineering? If anybody makes a non-progressive spring for the EVO, those guys will probably know about it.

I'm pretty sure the Tein S. Tech's are actually linear. They list a linear spring rate and not a dual or triple rate. So that may be a possible. There are also some Gold something or other brand available at www.procarparts.com that I believe are linear. Not 100% sure... but also not 100% sure why you'd want linears and not progressive? any particular reason?

They make coilovers

 

From Tein's website. Pardon my ignorance, but how can one tell if a spring is linear or progressive from spring rates?

 

The Evo will be eligible to roadrace in SCCA's Touring 2 class in Jan. 2004. I would like to request a lowered set of springs of about the stock rates. Progressive springs are not good at the limit because the rate is too variable. In Touring you can run a double-adjustable race shock, but not coilovers.
Cheers,

 

Andrew, it's not a 100% sure thing that you can determine if a spring is linear or not by the posting of rates. the thing with progressive springs is that they have about 2-4 spring rates along their length. It's why they are called progressive as they get progressively stiffer. My coiling at different widths and coil spacings they are able to achieve an initially soft response and then a stiffer response oustide of that initial give. Therefore it makes it hard to publish a clear single spring rate as that would be inaccurate to the actual spring performance. Versus a linear spring is one single coil style and spring constant throughout its length. So that's the only reason i made the comment I did. It doesn't mean that the Teins are guranteed to be linear... it's just likely or possible because of the fact that they clearly publish a single rate for the springs. (I was looking at the STech's for the USDM Lancer when I saw a single rate... they haven't published their evo spring specs)

And Limey... they make coilovers and plain springs in case you were trying to poitn out otherwise.

WTZ ... I follow you and I understand what you are saying as I know that progressive's vary a bit when pushed and the like... and if you are just lowering the vehicle and keeping stock rates then I totally understand and agree... as that isn't a bad way to go at all!! I wanted my ride lower AND stiffer hence I went progressive to achieve that with out killing all of my ride quality!

Just to elaborate on Steves excellent post, a progressively wound spring will have larger spacing between some coils and tighter spacing between others. If you bottom out this type of spring, the rate could potentially go to an astronomical figure causing your car to exhibit snap behavior. Steve- I don't think it's likely the SCCA will grant a spring package before the car races but it's nice to be prepared. If they were going to go along with my request, a linear lowering spring of about stock rates would have the best chance. After all, the Evo is a rally car, and looks really up in the air with 245/40/17 Hoosiers on it. Maybe I could argue it's so high that it might roll more readily and therefore is unsafe relative to street cars.
Cheers,

 

WTZ.... nice :-) That'd be great if they'd let you get a lowering spring on it... but I'd be half paranoid of arguing from the "it might roll" standpoint for them to declare the car itself unsafe. I'm surprised they aren't more prepared and ready for the EVO as they should have known that EVO owners were going to be wanting to run in the SCCA circuits more or less right away. It's not like they didn't know the car was coming, so why they weren't all set for it in the first place who knows.

I still have yet to see my first EVO in person :-(... but one of these days hopefully.
