H&R RSS37827-1 RSS Club Sport Coilover Kit

The H&R RSS37827-1 RSS Club Sport Coilover Kit is the firmest, highest-performing coilover system in the H&R street lineup — engineered for the dedicated motorsport enthusiast who demands maximum handling precision on the road and track. Designed and tested on the famous Nürburgring, this coilover kit delivers the ultimate in vehicle feedback, flat cornering, and supreme directional control.

Unlike conventional twin-tube or sleeve-over systems, the RSS Club Sport features a mono-tube gas shock construction with a fully threaded shock body. This true coilover design — not an imitation sleeve kit — allows precise, independent ride height adjustment via easy-to-use spring seat collars. Springs are crafted from H&R's special shot-peened 54SiCr6 spring steel, and the threaded plated steel shock bodies are engineered to minimize unsprung weight while providing excellent corrosion protection and high heat dissipation. Every unit is hand-assembled in Germany to strict ISO 9001 and TÜV standards.

Key Features:

• H&R Exclusive Dynamic Damper Technology — consistent, predictable damping under hard driving conditions
• Mono-Tube Gas Shock Construction — superior heat dissipation and fade resistance vs. twin-tube designs
• Fully Threaded Shock Body — genuine coilover design with precise ride height adjustability; not a sleeve-over imitation
• Higher Spring Rates & Aggressive Shock Valving — more performance-oriented than H&R Street Performance coilovers
• Lowered Center of Gravity — reduces body roll for flatter cornering and improved directional control
• Ride Height Adjustability — allows corner balancing for track use
• Shot-Peened 54SiCr6 Spring Steel — premium material for durability and consistent spring rate
• Hand-Assembled in Germany — built to ISO 9001 and TÜV standards
• 1-Year Warranty — covered for the original purchaser

Installation Notes: Professional installation is recommended. A suspension alignment will be required after installation. Note: Proper function of the suspension may require removal of the original rear torsion bar suspension on applicable vehicles.

The H&R RSS Club Sport coilover system is the ideal choice for drivers who regularly participate in track days, club sport events, or time attack — and want a street-legal suspension that performs like a race setup.
