KW V3 Coilover Kit – BMW Z4 M40i (G29)

OVERVIEW

KW's Variant 3 coilover kit lets a modified Z4 M40i be tuned rather than simply lowered. The patented KW valve technology separates rebound and compression adjustment, so the vehicle-specific base setup can be adapted to driving style or to changes in weight, tire characteristics and chassis bracing.

Compression damping can be raised to help tire grip, sharpen cornering behavior and limit squat without altering the rebound damping that is matched to the spring rate. Height adjustment is continuous and the dampers use KW's inox-line stainless steel housings.

Additional Parts Required

• A four-wheel alignment after installation is mandatory — camber, caster and toe all change with ride height.
• Professional installation is strongly recommended; a lift and spring compressors are required.
• Cars fitted with factory electronic dampers need the electronic-damper version instead: KW V3 Coilover Kit with Electronic Dampers – BMW Z4 M40i (G29).
• Driver assistance systems that reference ride height (headlight leveling, camera and radar aiming) should be checked and recalibrated after lowering.
• Tire-to-strut and fender clearance must be checked at the chosen ride height before the car is driven.
