I don't think the spring rates changed in 06-07, they just added VSA and a few extra braces to the chassis. Someone can check the part numbers to be sure.

OEM:
00-01 Fr: 218(3.9) - Rr: 291(5.2)
02-03 Fr: 240(4.3) - Rr: 230(4.1)*
04-07 Fr: 256(4.57) - Rr: 207(3.7)*
08-up Fr: 274(4.89) - Rr: 225(4.0)*
08CR Fr: 375(6.7) - Rr: 264(4.71)*


*Estimates based on published % changes from Honda.

Still, the spring rate for the PSS9 is relevant if you are comparing differences in brands of springs available for the S2000. It's interesting to see where the PSS9 rates fall against the other OEM and aftermarket springs.

The spring on the PSS9 acts on the suspension in the same manner as any of the others mentioned. The stock shocks are the same coilover design, the PSS9 simply has the extra features of adjustable damping and adjustable height. The helper springs (in general) are designed to keep the main spring in place under full suspension droop and are (usually) fully compressed when the car is resting on the ground, essentially becoming a solid spacer in normal operation.

Interesting thread. Nice work

I can't find it now but Honda published the original S2000 specs somewhere, a JDM sales brochure or something like that. Then they published that the 2002 cars had 10% stiffer front springs and 20% softer rear springs.

any one running the ground control/koni yellow setup and have an opinion on ride quality and noise concerns? Its a setup I'm considering and was wondering if anyone had any insight on this setup

im looking for a good 1.5 drop all the way around.....and tein , h&r, espelir all show a 1.5 in drop but everyone on the forums this and honda tech are showing only a 1in drop ....and its not worth it for me to buy a coilover set up and drop it cause if i got lower than 1.5 i wont be able to pull into my drive plz give suggestion

All the drop/lowering numbers that I've compiled have come from the manufacturers website so as to eliminate any subjective opinions.

You can trust those numbers.


Also remember that if you choose Koni's to replace the OEM struts, you have two choices for perches.....OEM height or an additional .5" so you can combine a drop from a spring and an additional .5" if thats what you want.

I used the Eibach Pro-Kit, gave me the drop I wanted.
