KW Coilover Kit Variant 4 (V4) 3-Way Adjustable – BMW M2 / M2 Competition / M2 CS (F87)

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 M2 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.

This listing covers the F87 M2 platform. Choose 3A7200BH for an M2 or M2 Competition with no factory electronic dampers — RWD only, this fitment is not offered for an xDrive drivetrain. Choose 3A7200DY, KW's Bundle for the M2 CS, which ships with the KW ESC/EDC cancellation module because the CS comes from the factory with adaptive dampers.
