KW Height Adjustable Springs – BMW 1M / M3 (E90/E92)

OVERVIEW

KW Height Adjustable Springs (H.A.S.) are the simplest way to give an E82 1M or E9X M3 a lower, more aggressive stance without stepping up to a full coilover kit. The kit pairs KW springs with threaded collars that work with the factory dampers, so the car keeps its OEM damping while gaining an adjustable ride height.

Because the original dampers stay in the car, installation is straightforward and the factory damper hardware and its functionality are retained. The result is a sporty but comfortable ride with improved handling and a noticeably tighter look.
