H&R RSS13908-1 RSS Coilover Kit Height Adjustable Performance Suspension

The H&R RSS13908-1 is a complete front and rear coilover kit engineered for the performance-driven enthusiast. Developed and rigorously tested on the famous Nürburgring, the RSS Coilover system is built to deliver maximum vehicle feedback, flat cornering, and precise directional control on both street and track.

At the core of the RSS system is H&R's exclusive dynamic damper technology paired with a fully threaded shock body — not an imitation sleeve-over — allowing straightforward, accurate ride height adjustment without sacrificing structural integrity or performance.

Key Features:

• Height Adjustable: 1.0" to 2.3" average drop (approx. 1.2"–2.3" front / 0.8"–2.0" rear)
• Fully Threaded Shock Body: Genuine full-thread design — not a sleeve-over — for precise and reliable height adjustment
• H&R Exclusive Dynamic Damper Technology: Tuned spring rates and shock valving optimized for high-performance driving
• Monotube Shock Design: Delivers precise control and improved response over twin-tube alternatives
• Lowered Center of Gravity: Reduces body roll and improves cornering stability
• Handcrafted in Germany: Manufactured to strict ISO 9001 and German TÜV standards

H&R RSS coilovers strike an ideal balance between spirited street performance and track-day capability. The combination of higher spring rates, precisely tuned dampers, and a fully adjustable ride height makes the RSS series a trusted choice for drivers who demand more from their suspension without giving up everyday drivability.
