H&R RSS29170 RSS Club Sport Coilover Kit - Adjustable Mono-Tube Street Performance Coilovers

The H&R RSS29170 RSS Club Sport Coilover Kit is the top-tier coilover system in the H&R street lineup, engineered for drivers who demand maximum handling performance on both the street and track. Designed and tested on the famous Nürburgring, this coilover kit delivers flat cornering and supreme directional control through higher spring rates and more aggressive shock valving than standard H&R street coilovers.

Built around a mono-tube gas shock construction, the RSS29170 features threaded plated steel shock bodies that minimize unsprung weight, provide corrosion protection, and allow efficient heat dissipation — critical for sustained track use. Springs are crafted from shot-peened 54SiCr6 high-fatigue spring steel for long-lasting performance and durability. Each kit is hand-assembled in Germany to strict ISO 9001 and TÜV standards.

Key Features:

• Mono-tube gas shock construction for precise, responsive damping
• Front-adjustable damping via knob on the bottom of the shock body
• Fully threaded shock body (not a sleeve-over) for true ride height adjustment

• Shot-peened 54SiCr6 spring steel construction
• Hand-assembled in Germany to ISO 9001 and TÜV standards
