Description
The AST Suspension 4100 Series suspension for Honda S2000 (AP1/AP2) provides a tunable damper system for drivers developing a setup around their vehicle, tires and intended use.
Rebound adjustment changes resistance as the suspension extends after compression. It provides a focused damping adjustment for evaluating how the car recovers from bumps and responds between braking, cornering and acceleration. Work from a recorded baseline rather than assuming the firmest setting produces the best response.
Key specifications
- Adjustable rebound damping.
- Ride-height adjustment on the supported configuration.
- OEM top-mount compatibility is application-dependent; do not assume replacement mounts are included.
- Manufacturer part number: ACS-H1301S.
Installation and setup
Check the application, wheel clearance and suspension travel before selecting the final ride height. Establish alignment and, where appropriate, corner weights before tuning damping. Change one setting at a time and record the result so a useful baseline can be restored.
