Ksport CNS230-RR Version RR Road Race Coilover Kit 36-Way Adjustable Damping

The Ksport Version RR (CNS230-RR) is a purpose-built road race coilover system engineered exclusively for track competition. Featuring stiffer spring rates, aggressive shock valving, and a 20–30mm shorter shock stroke compared to street-oriented designs, this kit is tuned to deliver maximum cornering response and uncompromising track performance. Not intended for street or daily driving use.

36-Way Adjustable Damping

The damping system offers 36 individual settings, simultaneously adjusting compression and rebound with a single knob for fast, straightforward setup changes at the track. This wide adjustment range allows drivers to precisely dial in handling characteristics across varying track surfaces and conditions.

Monotube High-Pressure Shock Design

The Version RR utilizes a monotube shock construction in which oil and gas are fully separated within the cylinder. Compared to twin-tube designs, the monotube configuration dissipates heat more effectively, enables finer damping calibration, and significantly reduces the risk of aeration and cavitation — all critical advantages under sustained race conditions.

Aerospace-Grade Aluminum Construction

Mounts, collars, and spring perches are machined from 6061-T6 billet aluminum, producing a kit that is lightweight, highly durable, and rust resistant. Steel shock bodies receive a zinc electroplate coating for added protection against corrosion and the elements.

Pillowball Upper Mounts

On applicable fitments, heavy-duty all-steel pillowball upper mounts replace rubber-isolated OEM mounts to provide a more direct, connected steering feel and improved driver feedback. On many applications, the pillowball mounts also offer camber adjustment, eliminating the need for a separate camber kit. A patented top nut and bearing kit helps minimize noise during low-speed turns.

Adjustable Lower Mount for Height Without Sacrificing Travel

Most applications utilize an adjustable lower mount design, allowing ride height changes without reducing suspension travel — a common drawback of spring-perch-only height adjustment found on competing designs.

Valving Matched to Spring Rates

Each kit's shock valving is specifically calibrated to the installed spring rates, ensuring consistent damping behavior and reliable performance. Custom spring rates are available for specialized builds.

Integrated Dust Boot and Bump Stop

Dust boots are standard on all Version RR coilovers, with the bump stop integrated inside the dust boot for a more compact, durable package that resists deterioration over time.
