Ksport CMZ320-AR Asphalt Rally AR Spec Coilover Kit with 36-Way Damping

The Ksport CMZ320-AR Rally AR Spec Coilover Kit is an competition-grade suspension system engineered specifically for the demands of asphalt rally racing. Built with extended-stroke shocks and heavy-duty internals, this kit is designed to handle the punishment of tarmac stages and hard-driven roads where lesser coilovers fade or fail. Spring rates and shock damping settings are carefully matched per application to stabilize the vehicle and absorb the impacts of uneven road surfaces.

Key Features:

• 36 Levels of Damping Adjustment — Simultaneous compression and rebound adjustment via a single knob for quick, precise tuning on the fly
• Inverted Monotube Shock Design — Oil and gas are separated within the cylinder for superior heat dissipation and finer damping control compared to twin-tube designs; significantly reduces aeration and cavitation
• Large Diameter Pistons — Increased oil capacity improves cooling efficiency under sustained high-performance driving
• 6061 Billet Aluminum Construction — Mounts and major coilover components are machined from 6061 billet aluminum for a lightweight, durable, and corrosion-resistant build
• Zinc-Electroplated Steel Shock Body — Provides robust protection against rust and environmental exposure
• Adjustable Lower Mount — Allows ride height adjustment without sacrificing suspension travel, unlike many competing coilover designs
• Pillow Ball Top Mounts (Application-Specific) — Available on select front and rear applications to preserve OEM suspension geometry while delivering a more direct, responsive driver feel
• Integrated Camber Adjustment — On applicable pillow ball top mount configurations, camber can be adjusted directly at the coilover without a separate camber kit
• Valving Matched to Springs — Each kit is valved to complement the installed spring rates for consistent, reliable performance
• Up to 3 Inches of Ride Height Reduction — On most applications, the system supports OEM ride height and allows lowering up to 3 inches from stock level

The Rally AR Spec uses a monotube shock architecture in which pressurized gas and hydraulic oil occupy separate chambers. This design dissipates heat more effectively than twin-tube alternatives, supports finer incremental damping adjustments, and greatly reduces the risk of aeration and cavitation during extended competition use.

Rally Height Note: On many (but not all) applications, this system supports achieving OEM ride height — an important consideration for competitors subject to ride height regulations enforced by sanctioning bodies in tarmac rally events.
