KW Coilover Kit Variant 4 (V4) 3-Way Adjustable – BMW M3 / M4 (F80 / F82 / F83)

OVERVIEW

The KW Variant 4 is KW's three-way adjustable coilover for fast road and track use. Low-speed compression, high-speed compression and rebound are set on separate adjusters, so body control over curbs and big compressions can be dialed in without also making the car harsh over small inputs. That separation is the whole point of a 3-way damper and it is what the Variant 3 cannot do.

On the F8X M3/M4 the factory damper is the limit long before the engine is. Stock struts run a fixed valving curve chosen for showroom ride quality, and the ride height is not adjustable. The V4 replaces the strut assembly outright with an adjustable-height, adjustable-damping unit and a camber-adjustable top mount.

This listing covers the F80 M3 and F82/F83 M4. Choose 3A7200AN if your car has no factory electronic dampers. Choose 3A7200AP, KW's Bundle, if it does — the Bundle ships with KW's ESC/EDC cancellation module so the adaptive dampers are deleted without setting fault codes.
