HKS 83003-KH001 Yamaha Performance Damper for 1999-2009 Honda S2000 AP1 / AP2

Vehicle Fitment

• 1999-2003 Honda S2000 (Base Convertible - AP1 Chassis, F20C 2.0L DOHC VTEC I4, RWD)
• 2004-2009 Honda S2000 (Base Convertible, CR - AP2 Chassis, F22C 2.2L DOHC VTEC I4, RWD)

Fitment Notes

• Covers both generations of the S2000: the AP1 (1999-2003, F20C 2.0L) and the AP2 (2004-2009, F22C 2.2L). Both chassis share the same mounting points for this damper.
• This is a chassis-mounted micro-vibration damper - it does not replace or interact with coilovers, shocks, or any suspension component. Compatible with stock and aftermarket suspension setups.
• Performance characteristics are best realized when paired with the HKS HIPERMAX S coilover kit, which creates an optimally balanced system of ride comfort and handling refinement.

Features

• Yamaha Performance Damper® technology licensed from Yamaha Motor Co., Ltd. and vehicle-specifically tuned by HKS for the Honda S2000 AP1/AP2 chassis
• Operates at micrometer displacement scale - targets high-frequency micro-vibrations transmitted through the S2000's rigid chassis from road surface, tires, and body flex
• Reduces chassis flex and unwanted body play, delivering sharper, more precise cornering feel with reduced vagueness at the limit
• Suppresses in-cabin NVH (Noise, Vibration, and Harshness) - improves interior refinement and reduces driver fatigue, especially at highway speeds
• High-pressure nitrogen gas-charged oil damper with ultra-low piston speed characteristics and cancelled gas reaction force - no additional pressurization placed on the chassis
• Optimized damping saturation characteristics ensure smooth, natural response across all driving conditions from daily commuting to track use
• Direct bolt-on installation with no cutting, welding, or modification required

Product Description

The HKS 83003-KH001 is the Yamaha Performance Damper® for the 1999-2009 Honda S2000, covering both the AP1 (F20C 2.0L) and AP2 (F22C 2.2L) chassis generations. Licensed from Yamaha Motor Co., Ltd. and tuned by HKS specifically for the S2000's already-rigid roadster platform, this chassis micro-vibration damper targets the high-frequency micro-vibrations that transmit through the body from road surface input, tire feedback, and structural flex. Operating at a micrometer displacement scale - far finer than conventional suspension components - it reduces chassis flex and play without altering ride height or suspension geometry, resulting in handling that feels simultaneously sharper and more composed.

The S2000's lightweight, high-revving character makes it particularly responsive to chassis refinement upgrades, and the Performance Damper enhances this by also suppressing in-cabin NVH. The result is improved interior quietness and a more connected driving experience - especially noticeable at higher speeds and on back roads where micro-vibration is most pronounced. Installation is direct bolt-on with no modifications required, and the unit is fully compatible with both stock and aftermarket suspension setups. Pairing with the HKS HIPERMAX S coilovers is recommended for the most complete system-level improvement in ride and handling balance.
