Product Details

The Ksport CMZ321-RR Version RR Road Race Coilover Kit is engineered exclusively for track and road racing applications. Featuring aggressive spring rates and precisely matched shock valving, this monotube coilover system delivers maximum handling performance with sharp, immediate response and unmatched control on the circuit. For race use only — not intended for street use.

Key Features:

  • 36-Way Adjustable Damping: Fine-tune compression and rebound simultaneously with 36 levels of damping adjustment, allowing precise setup for any track condition or driving style.
  • Monotube High-Pressure Design: Oil and gas are separated within the cylinder for faster, more even heat dissipation compared to twin-tube designs. Greatly reduces the risk of aeration and cavitation for consistent, reliable performance lap after lap.
  • Pillow Ball Upper Mounts: Heavy-duty all-steel pillow ball top mounts (on applicable fitments) provide increased steering response and direct driver feedback. Ksport's patented upper pillow ball mount design helps combat noise while maintaining the compliance required by high-demand strut applications.
  • Camber Adjustment: On select applications, the pillow ball upper mounts provide built-in camber adjustability, eliminating the need for a separate camber kit.
  • Adjustable Lower Mount: Most applications feature an adjustable lower mount for ride height changes without sacrificing suspension travel — a common shortcoming in competing coilover designs.
  • 6061-T6 Billet Aluminum Construction: Mounts, collars, and spring perches are machined from 6061-T6 billet aluminum for a lightweight, durable, and corrosion-resistant build.
  • Zinc-Electroplated Steel Shock Bodies: The steel shock bodies are zinc electroplated to resist rust and protect against the elements during extended track use.
  • Matched Valving: Each shock is valved specifically to match its installed spring rate for optimal ride quality, consistency, and reliability.
  • Upgraded Bump Stops: Integrated bump stops inside the dust boot protect the damper seal and prevent shock-out damage over uneven pavement or harsh track surfaces.
  • Custom Spring Rates Available: Choose from proven Ksport spring rate settings or specify your own custom rates — shocks will be valved to match your selection.
  • Ride Height: Lowering range of approximately 2 to 4.7 inches depending on application.
  • 12-Month Limited Warranty: Backed by Ksport's 12-month warranty covering manufacturer defects.

The Ksport Version RR coilover system represents a purpose-built racing suspension solution for drivers who demand maximum adjustability, precise handling, and proven track performance. Whether you're competing in autocross, time attack, or circuit racing, the CMZ321-RR delivers the edge serious racers require.
