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.

TECH RESOURCES
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 w/ Electronic Dampers.
- 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.
Installation
- KW supplies printed installation instructions in the box. KW does not publish a public download for order number 352200CG — contact Speed Logic if you need a copy of the instructions before installing.
