Product details
OVERVIEW
The KW V1 is KW's entry-level coilover: you set the ride height, and KW sets the damping. KW develops the damper valving and spring rates for the GR Supra and Z4 on its 7-post test rig and the Nürburgring Nordschleife, aiming for a sporty but everyday-usable balance that reduces body roll and sharpens steering response.
Ride height is adjusted with a one-piece composite collar on the front struts and a separate height adjuster at the rear, on KW's dirt-resistant trapezoidal thread, so it stays easy to change for years. The struts are inox-line stainless steel with corrosion-resistant springs and bump stops, built in Fichtenberg, Germany.

TECH RESOURCES
Additional Parts Required
- None for cars with standard (non-electronic) dampers.
- Cars with factory adaptive (electronic) dampers need their electronic dampers shut down; choose the KW V1 Coilover Kit (EDC) – Toyota GR Supra (A90) / BMW Z4 (G29), which includes KW's deactivation kit.
- A four-wheel alignment is required after installation and after any ride-height change.
- Check tire-to-strut and tire-to-fender clearance at the chosen ride height; KW specifies a minimum of 5 mm.
- Cars with ride-height sensors or camera/radar driver-assistance systems need those systems adjusted or recalibrated after lowering.
