S3 Suspension Technical Information

Suspension Technology

No Compromise

The key to optimizing vehicle performance with a coilover system falls entirely on the damper it's built around. S3 Suspension coilover kits have decades of proven damper engineering technology built into each system. Each damper is carefully assembled harnessing premium components that are made to last under the extreme conditions that racing vehicles are put through.

Thanks to our unique development process and our component manufacturing partners, S3 coilovers are an affordable option that delivers optimal performance for your vehicle without any of the drawbacks or problems found in other systems at similar price points.

S3 coilovers are a premium option without the premium price tag!

Specially Tuned

We pride ourselves on our extended development processes and attention to detail. Each coilover system features specially formulated valving, tuned specifically for each vehicle application and spring rate combination.

Each solution is assembled and first tested on a shock dyno to ensure proper operation and verify that the valving produces the results we are looking for. Next, the system is then installed on a vehicle for fitment checks and put through the motions to ensure proper operation.

From there, it's off for road testing and then the track for extensive testing with multiple professional drivers to gather data, feedback, and look for any unexpected defects or problems that might develop.

Our systems are brought back, torn down for inspection, and go through this testing process multiple times until we determine that it's delivering the excellent performance that we expect and is ready for your vehicle!

Monotube

Monotube dampers are the standard in the performance suspension industry, and S3 is no different. Unlike the twin-tube dampers found in many OEM applications, monotube dampers offer the best performance in the smallest package while also delivering a wealth of other benefits.

Separated oil and gas chambers
No aeration or foaming
More responsive valving
Higher gas pressures
Cooler temperatures
Evenly distributed pressures
Less shock fade
More consistent performance
Improved control and response
More predictability and control
