KW V3 Coilover Kit – BMW M2 / M3 / M4 (G8x)

OVERVIEW

The KW Variant 3 brings a genuinely track-worthy package to a street car through its dual damping technology. Rebound and compression damping are adjusted separately and independently, so the suspension can be fine tuned rather than compromised. KW's patented two-stage valve system gives you the rebound adjustment that governs comfort and the low-speed compression adjustment that governs driving dynamics, while the high-speed range — the one that determines driving safety — stays fixed.

KW was founded in 1995 with three employees and a small operating area. Today the company is represented worldwide with roughly 200 employees across five locations, offers the largest suspension program in the world, and tests every component on its own seven-post drive dynamics rig.

TECH RESOURCES

Additional Parts Required

• Four-wheel alignment — a full four-wheel alignment is mandatory after installation and after any subsequent ride-height change.
• Professional installation — KW specifies fitment by a qualified suspension shop; installation at a KW specialist dealer is also what qualifies the kit for KW's extended warranty coverage.
• Tire-to-strut and fender clearance check — verify clearance at full lock and full compression, particularly with aftermarket wheel and tire packages.
• Ride-height sensor handling — cars fitted with headlight-leveling or adaptive-damper ride-height sensors require the sensor links to be relocated or adapted to the new ride height per KW's instructions.
• Driver-assistance recalibration — camera- and radar-based driver-assistance systems must be recalibrated after the vehicle is lowered.
• Installer-supplied tools: spring compressor, torque wrench, and the standard BMW suspension service tools.
