Audi A4 Coilover Suspension Kit - KW V1 INOX-LINE (’17–’27). A height-adjustable stainless-steel coilover system with pre-set damping that delivers balanced, sporty street performance for the B9 A4.

Built around KW’s INOX-LINE stainless struts and corrosion-resistant springs, V1 is tuned specifically for the A4 to blend confident handling with everyday comfort. Set your ride height within the approved lowering range while maintaining proper suspension travel. The dirt-resistant trapezoid thread and composite adjustment collar keep height changes easy even after years on the road. Vehicle-specific spring rates and damper curves reduce body roll and sharpen response. Each damper is dyno-tested, and development includes Nürburgring and 7-post rig validation. Backed by a Limited Lifetime Warranty with unlimited mileage.
