KW Variant 1 ‘INOX-LINE’ Coilover Kit is KW Suspension’s entry level performance coilover kit. The high quality inox-line stainless steel coilover struts, corrosion resistant springs, bump stops and dampers are optimally tuned resulting in a balanced and sporty feel, specific to vehicle application, and designed for long lasting driving pleasure.


Maximum lowering can be achieved with KW Variant 1 ‘INOX-LINE’ coilovers that, within an approved lowering rate, ensure proper functioning suspension and adequate travel when the vehicle is lowered. Ride height continues to be easily adjustable, even after years of use, due to the dirt resistant trapezoid thread and composite adjustment collar.


The pre-configured vehicle specific damper setup and spring rate increase driving pleasure with an optimal balance of comfort, sportiness, practicality and safety. Vehicle body roll is reduced during compression to give the benefit of more genuine and direct handling while driving.


The KW Variant 1 ‘INOX-LINE’ Coilover Kit has been developed and manufactured in-house at KW’s facility in Germany, specifically for the particular vehicle. The V1 coilovers undergo comprehensive stress testing and fine tuning, as do all KW coilovers, at their 7-post Driving Dynamic Test Center and on the Nürburgring.
