OVERVIEW
The KW Variant 3 coilover kit for the A90 GR Supra and G29 Z4 is built for owners who have already started modifying the car and want a suspension that can be tuned to match. KW's patented valve technology separates rebound and compression adjustment, so the vehicle-specific base setup can be adapted to driving style and to changes in weight, tire choice or chassis bracing.
Compression damping can be increased to help tire grip, improve cornering behavior and reduce squat without disturbing the rebound characteristics that are 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 w/ Electronic Dampers — 2020 Toyota GR Supra A90.
- 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.
