KW V1 inox-line coilover suspension for BMW 3 Series G20 saloon

Give your BMW 3 Series G20 the stance, control and confidence it deserves with the KW V1 inox-line coilover suspension kit. This road-focused, height-adjustable package delivers sharp handling and a composed ride on UK roads, with stainless steel damper bodies for long-term durability in all weather. Expect precise steering, reduced body movement and a clean, even drop that looks right with both factory wheels and aftermarket setups.

How it drives

The KW V1 setup offers a composed, refined ride with a decisive step-up in grip and response.
