Transform your BMW 4 Series F33 Convertible xDrive with the KW Variant 3 Coilover Kit. The iconic KW V3 delivers height adjustable coilovers with truly independent rebound and compression damping adjustment, giving you the perfect balance of ride comfort and track-capable performance. Built with KW inox-line stainless steel for long-term durability and consistent performance, this is the go-to premium coilover suspension for BMW F33 owners who demand sharper handling, confident stability and precise control on British roads and beyond.
We run KW V3 on our own builds and our customers consistently rate the ride quality, steering response and overall grip as a night-and-day upgrade over factory suspension and basic lowering springs.

What you can adjust and why it matters
Dial up rebound to reduce body movement and sharpen steering feel. Add compression for flatter cornering and support under braking without changing spring rates. The KW V3 gives you the control to fine tune directional stability, turn-in, mid-corner balance and ride quality to suit your tyres, wheel size and driving style.
