Our motorsports program running the 25 Hours of Thunderhill in 2021 with the FK8 and with the FL5 in 2023, led us to develop coilover suspensions for the FK8/FL5 in partnership with KW USA.
The vast data accumulated from racing served as the bases of our suspension development, setting an ambitious goal to create a product optimized for track, street and the winding roads. After numerous testing on the track and on the winding roads, we are proud to introduce this full-spec coilover kit.


The damping force can be adjusted in two ways, by rebound or compression, and the front is equipped with a camber-adjustable upper mount,
allowing for a wide range of adjustments to suit the driving stage.
Experience the smooth, flat ride when driving around town and the direct, smooth cornering that rivals that of a racing car when driving in sports mode.
Designed with a 2-Way adjustable damping system, the front pair comes with camber adjustable upper-mounts to accommodate various driving environments.
Providing a smooth flat ride on the street, the suspension can be adjusted for more direct and aggressive cornering feel for track use.
