Ksport CMZ290-RR Version RR Road Race Coilover Kit with 36-Way Damping

The Ksport CMZ290-RR Version RR Road Race Coilover Kit is engineered exclusively for track and road racing applications. This is a race-only system — it is not intended for street use. Featuring aggressive spring rates and purpose-matched shock valving, the Version RR delivers maximum handling precision, acute throttle response, and unparalleled responsiveness on the circuit.

Key Features:

• 36-Way Adjustable Damping: Simultaneous compression and rebound adjustment across 36 distinct settings allows precise tuning to match any track condition or driving style.
• Race-Optimized Spring Rates & Valving: Aggressive spring rates — Front: 14 kg/mm, Rear: 12 kg/mm — are paired with shock valving specifically matched to the installed springs for consistent performance and reliability.
• 20–30mm Shorter Shock Stroke: The reduced stroke combined with stiffer rates delivers the tighter, more predictable suspension behavior demanded by competitive road racing.
• Upgraded Bump Stops: Heavy-duty bump stops are integrated within the dust boot to prevent shock bottoming on uneven pavement or under hard cornering loads, while also resisting deterioration over time.
• Monotube High-Pressure Design: Oil and gas are separated within the cylinder for faster, more even heat dissipation compared to twin-tube construction. Reduced aeration and cavitation result in consistent damping performance under sustained track use.
• Pillow Ball Upper Mounts (Select Applications): Front and rear pillow ball top mounts preserve OEM suspension geometry while delivering a more direct, communicative steering feel. On many applications, the pillow ball mount enables camber adjustment, eliminating the need for a separate camber kit.
• Adjustable Lower Mount: Height adjustment via the lower mount allows ride height tuning without sacrificing suspension travel — a common drawback of inferior coilover designs.
• 6061-T6 Billet Aluminum Construction: Mounts, collars, and spring perches are machined from aerospace-grade 6061-T6 billet aluminum for a lightweight, durable, and corrosion-resistant build.
• Zinc-Electroplated Steel Shock Bodies: Steel damper housings are electroplated with zinc for long-lasting protection against rust and environmental exposure.
• Custom Spring Rates Available: Shocks can be valved to custom spring rate specifications, allowing racers to tailor the system to their exact setup requirements.
• 12-Month Limited Warranty: Covered against manufacturer defects for 12 months from the date of purchase.

Race Use Only. The Ksport Version RR coilover system is purpose-built for competitive road racing and is not recommended for street driving. For those seeking a system that balances track capability with everyday usability, consider the Ksport Kontrol Pro (CMZ290-KP).
