.5"

Is that the right spring rate for the stock springs? If so why are the Eibach springs so soft, I was looking into getting a set. I like the fact they only have a 1" drop all around.

Hopefully you got the data from the manufacturers and not from message boards.
RS-R has different figures. http://www.rs-r.com/suspension_springs.htm
I'd also take rates for progressive spring with a grain of salt, since they're not static like linear springs.

nOOdle,
Thanks for the web site. I when looking for it and never found it. The chart has been updated.
Keep them coming!! From what I hear and found, The Eibach Pro-Kit are soft.

What are the Evo's stock spring rates?

Is there really that much to be desired with the suspension, that it needs to be modified significantly?

Is there any one company that shines at suspension systems for these cars?

My appologies for being a n00b.

wojo · Feb 22, 2004, 10:14 PM

Your JIC FLT-A2 rates are reversed. The front is 10k and rear is 9k

Tri-Bar · Feb 23, 2004, 09:39 AM

Thanks wojo. list has been updated. Does any one know the rates for the Ohlins Road/Sport coilovers I have not been able to find it.

The stock spring rate are soft front 180lbs(3.2k) rear225lbs(4.0k). The struts and shock are highly valved for high speed damping,but lack the low speed we need for the street, will know more on them when I can get over on a shock dyno to test them out better. There are a few stand outs on the suspension system side. Cusco, JIC, Ohlins,DMS. I my self are looking into the Ohlins for a good over all system(street and track).

ralliart is .5 all the way around.... ? I was hoping 1" .... what about the Espleirs?

Because they are progressive rate. I think that information needs to be added.
