KW Coilover Kit V2 – BMW 230i / 330i / 430i / M240i / M340i / M440i (G20 / G22 / G42, RWD, Non-EDC)

OVERVIEW

The KW V2 coilover adds adjustable rebound damping to a height-adjustable KW coilover. Rebound is set in 16 clicks with the supplied adjuster at the top of the piston rod, so you can firm the car up for more body control and stability at speed, or soften it for comfort, without changing the compression valving.

KW develops each kit's damper settings and spring rates on its 7-post test rig and the Nürburgring Nordschleife. Ride height is adjusted on KW's dirt-resistant trapezoidal thread using the stainless steel front struts and a separate rear height adjuster, and the struts are inox-line stainless steel built in Fichtenberg, Germany.
