Does anyone know in detail what exactly are the suspension differences between 03 and 04 s2000's? Spring rates, shock valving, etc.

 

I believe and correct me if I'm wrong, the only difference is the rear sway bar was changed.

 

Front springs 6.5% stiffer, rear springs 10% softer.

Don't know about shock valving.

Steering ratio is slower.

 

The shocks we re-tuned to integrate with the changes in tire, wheels, spring rates, chassis, etc.

Here is what I found on Hondanews.com:
"... the body and frame are a hybrid monocoque-frame structure that forms a highly rigid platform for the S2000's in-wheel double wishbone suspension system, and plays an important role in helping the S2000 achieve its high level of safety protection. Body rigidity has been increased for 2004 by strengthening key points on the body and chassis.

Performance and Handling
Dynamic acceleration increased
Transmission shifter direct feel increased
High-speed stability enhanced
At-the-limit performance increased with more gradual fall-off
Sensitivity to disturbances decreased (less bump steer)
Steering feedback enhanced
Brake pedal dynamic feel enhanced"

Springs
New Tuning
- Front: Increased spring rate 6.7%
Rear: Decreased spring rate 10%

Shock Absorbers
New Tuning
- Tuned for new suspension settings
