KW Coilover Kit Variant 3 (V3) 2-Way Adjustable – BMW 530i / 540i (G30)

OVERVIEW

The Variant 3 is KW's two-way adjustable coilover and the one most people actually want. Compression and rebound are on separate adjusters, so you can firm up body control without also killing rebound compliance, and ride height is continuously adjustable across the kit's range. It is the sensible step up from a spring-only kit and a large step up from the factory strut.

The stock damper is the limiting part on the G30 5 Series. Factory valving is a single fixed compromise and the ride height is whatever the car left the line at. The V3 replaces the whole strut with a rebuildable, height-adjustable, damping-adjustable unit.

This listing covers the G30 530i and 540i. 352200BY fits the RWD car; 352200BZ fits xDrive. Both are Bundle kits, supplied with the KW ESC/EDC cancellation module for the factory adaptive dampers.

PARTS INCLUDED

• Front and rear KW Variant 3 coilover units with matched springs
