KW V4

Four-Way Control, Zero Compromise 

The KW V4 represents the pinnacle of KW's street coilover range, adding high-speed compression adjustment to the already comprehensive setup options of the V3. Where most performance coilovers address only low-speed damping, the forces generated during cornering, braking, and acceleration, the V4 also controls high-speed compression, the damping behaviour triggered by sharp road impacts and fast driving manoeuvres at speed. The result is a suspension that can be precisely configured for both dynamic driving style and road surface conditions, without sacrificing daily usability.

The INOX Line Foundation 

Like every KW coilover, the V4 is built on the INOX Line stainless steel platform, full corrosion resistance without coating degradation during height adjustment, a composite polyamide spring seat that resists oxidation over years of use, and a dirt-resistant trapezoidal thread for reliable stepless lowering adjustment at any time. A parts certificate is included for straightforward homologation and vehicle registration.

Precision Engineering, 7-Post Validated 

Every V4 setup is developed and validated on KW's dynamic 7-post test rig, which simulates real driving conditions to optimise each vehicle-specific application before it reaches the customer. An external expansion reservoir is included to provide the necessary oil volume for sustained high-performance damping, and select applications feature aluminium struts alongside the standard INOX Line stainless steel construction. The unibal top mount further enhances steering precision and suspension response across the full range of adjustment.
