KW Clubsport 3-way tri-adjustable suspension for BMW F20 F21 F30 F32 platforms delivers serious pace on circuit and composure on the road. Built with stainless Inox-Line damper bodies and remote reservoirs, this motorsport-derived damper and spring package gives you precise control, exceptional stability and repeatable performance for track days, fast road and time attack use. Ideal for M135i, M140i, 335i, 340i, 435i and 440i owners chasing lap time and confidence-inspiring handling.
