The KW Height Adjustable Spring Kit (HAS) for the BMW G99 M5 Touring is an OEM+ suspension solution designed to improve stance and handling without replacing the factory adaptive dampers. Instead of locking you into a fixed lowering height like traditional springs, this system allows continuous ride height adjustment after installation, giving you precise control over stance, fitment, and ride balance.
Engineered specifically for the latest generation M5 platform with its hybrid-assisted twin-turbo V8 and advanced adaptive suspension, the KW HAS kit preserves full functionality of BMW’s factory electronic damping systems and drive modes. The result is a more aggressive stance, reduced wheel gap, and sharper chassis response while maintaining the comfort and refinement expected from a daily-driven M car.
This system is designed for enthusiasts who want a clean, reversible, factory-compatible lowering solution that enhances both aesthetics and driving dynamics without the compromises of a full coilover setup.
