Product Information
The ST XTA-Plus 3 is a height- and damping-adjustable coilover kit for the 2001-2006 BMW E46 M3, built by hand at KW in Germany. Each KW twin-tube damper offers 24 clicks of high-speed and 24 clicks of low-speed compression adjustment plus 18 clicks of rebound adjustment, so handling can be tuned for street or track. Ride height is set via the seamless thread on the galvanized strut housing, and the kit ships with linear race springs and aluminium unibal top mounts that improve steering feedback and allow camber adjustment.
