Version RR Road Race Coilover Kit

The Ksport CNS250-RR Version RR Road Race Coilover Kit is a purpose-built track suspension system engineered exclusively for road racing. Featuring aggressive spring rates and precision shock valving, this coilover kit delivers maximum handling performance with acute reaction and unparalleled responsiveness on the track. It is important to note that this kit is built strictly for road racing and track use and is not recommended for street use or daily driving. Key features of this coilover kit include 36-way adjustable damping, which simultaneously adjusts compression and rebound with a single knob for precise tuning. It also boasts stiffer spring rates and valving matched specifically to the installed springs, with a 20-30mm shorter shock stroke to optimize track geometry and responsiveness. The monotube high-pressure design separates oil and gas within the cylinder for faster, more even heat dissipation and finer damping adjustments, greatly reducing aeration and cavitation for consistent performance. Construction details include upgraded bump stops to prevent shock bottoming, pillowball upper mounts (available on many applications) to improve steering feel and response, and an adjustable lower mount for ride height adjustment without sacrificing suspension travel. The mounts, collars, and spring perches are machined from 6061-T6 billet aluminum for a lightweight, durable, and corrosion-resistant build, while the zinc-electroplated steel shock body protects against rust and the elements under demanding race conditions. Custom spring rate options are available, with shocks valved specifically to match selected springs. A 12-month limited warranty covers manufacturer defects. Spring rates are 18/1008kg/lbs in the front and 16/896kg/lbs in the rear. The upper mounts are ATM with aluminum construction and no camber adjustment. The design is monotube and gas-charged, with adjustable height and adjustable lower mount type.
