Has anyone ever tested how much stroke the rear has on any given damping setting? My coworker pointed it out to me, but when my car was on the lift, there doesn't seem like there would be much stroke given the large bumpstop and the helper springs which will compress. comments?

Ok, found this old SOS link:
Old Tein Suspension Info

It appears the Tein RS's come with 10k springs and can run up to 12k springs (672 lbs/in).

Tein SRC's come w/ 16k springs stock but I was unable to obtain information about optional SRC spring rates.

I believe Marty (Man Whore Racing) was the first one to try out the SRC's. Stinkytofu and I jumped on the coilovers once we drove a S2000 with Tein N1s. I am crossing the two year mark on my coilover and have yet to feel any wear on the shocks.

The KW V3 are a great shock for entry driver but it definably leaves alot to be desired when using R compounds. The spring rate is too low to use with any decent R-Compound tires and most users would end up closing down on the valving too much.

One should really match the spring rate with the type of tires your going to use. The standard SRC spring rate is 16kg and it should be used with high end 17" street tires or R compounds.

Most of the drivers on this forum with high end (cheating bastard! ) coilovers (moton, JRZ, etc) would know that their shocks are very smooth and mild in its operation.

Yes, the spring rate on the SRC is pretty high but because the shock is active, the ride is not too bad. I use a higher spring rate then the standard SRC and the ride quality is still at an acceptable level. I was not a fan Teins before the SRC but I really like the way the shock reacts to the spring movement. You could say that the initial valving response on the SRC's feels very much like a good European shock.

The SRC's are very good shocks but high end shocks are definatly better. The SRCs are a good compromise between cost and performance.

Would I want to upgrade to Motons or JRZ? Ofcourse but its also more then 2x the cost.

My recommendation is to use the SRC's with the proper tire (17") to extract its full potential and try to figure out what the shocks are doing. Sure, you can install these coils on a 100% stock S but it may not be balanced. (in terms of a package as a car)

In Japan, you can order 16, 18, 20kg/mm spring rate with the SRCs.

I got mine from a shop in Utah, Laketown Speed and sound ask for John. Shipped for $2380 or try any of the sponsor on here. I know Evasive sells them.
