The KW Variant 1 (V1) Coilover Kit is KW’s entry-level performance suspension designed to improve handling, ride quality, and stance without adjustable damping complexity. With factory-preset harmonic damper tuning and vehicle-specific spring rates developed through extensive testing, the V1 delivers a balanced blend of sporting performance and everyday comfort.

Lowering Range

• Front: 0.8″ – 2.0″ (20–50 mm)

• Rear: 0.4″ – 1.5″ (10–38 mm)

This adjustable range lets you achieve an aggressive lowered stance while maintaining suspension travel and geometry.

These spring rates provide a firm, controlled feel with reduced body roll and improved cornering stability, while still suitable for street use.
