Whether you drive daily, enjoy spirited B-road blasts or hit the track, V3 lets you set fast-road comfort or track-focused precision with simple, repeatable clicks.
Motorsport-derived technology
Drawing on KW’s experience in international motorsport, the Variant 3 uses proven twin-tube damper technology with patented valves for separate rebound and compression control. Adjust compression easily at the lower end of the stainless body without special tools. Rebound is adjusted via the top of the piston rod using the integrated wheel or the supplied adjuster, depending on application.
This is the benchmark coilover for performance cars and trusted by tuners and manufacturers worldwide thanks to its damping characteristics, premium finish and long-term reliability.
Built to last
The inox-line stainless steel construction is 100 percent rust-free for consistent performance year after year. The dirt-resistant trapezoid thread and composite spring perch make ride-height adjustments smooth and easy even after long-term use. KW quality management ensures every damper and every kit is extensively tested. KW offers up to five years warranty on the Variant 3 inox-line when installed by a KW specialist dealer.
