KW Variant 3 Coilovers – BMW 3 Series Sedan / Coupe (E90/E92)

OVERVIEW

KW Variant 3 brings race technology to the road with independently adjustable compression and rebound damping. State-of-the-art motorsport development is applied to a street suspension so the car can be set up to the driver's preference rather than to a single fixed compromise.

KW's patented dual-level valve system separates the two adjustments: rebound damping is set for road comfort and body control, while low-speed compression damping governs the driving dynamics. Ride height is continuously adjustable on the threaded stainless steel strut bodies.

This application is for the rear-wheel-drive BMW 3 Series E90 sedan and E92 coupe.

TECH RESOURCES

Additional Parts Required

• Four-wheel alignment after installation is mandatory — KW requires the suspension geometry to be reset to the vehicle manufacturer's specification once the final ride height is set.
• Professional installation required — KW states that suspension components must only be fitted by a trained workshop. Impact wrenches must not be used on piston-rod fasteners.
• Ride-height sensors must be disconnected and removed before strut removal on cars fitted with adaptive/xenon headlight leveling.
• Driver-assistance systems (radar and camera based) must be re-verified and recalibrated after the car is lowered.
• Check wheel and tire clearance to the strut body after installation; spacers may be required where clearance is marginal.
• Not for cars with Electronic Damper Control (EDC). EDC-equipped cars require a different KW application.
