BMW M3 Coilover Suspension Kit - KW - Height Adjustable Spring (H.A.S.) - 2015. This KW H.A.S. kit gives your 2015 M3 the ability to fine-tune ride height after installation while maintaining factory suspension functionality.
Designed for drivers who want precise ride-height control without replacing OEM dampers, the KW H.A.S. system uses vehicle-specific spring rates and high-strength chrome-silicon steel springs tuned to work with your factory adaptive or electronic suspension. The kit allows continuous, millimeter-precise adjustment within a tested range, includes vehicle-specific bump stops and dust protection to reduce wear, and improves steering response and handling balance without compromising driver assistance or comfort systems. Developed and manufactured in Germany, KW testing includes track development to ensure reliable performance and fitment.
