KW Suspension G90 / G99 M5 Height Adjustable Spring Kit

Improve the stance of your BMW G90 M5 Sedan or G99 M5 Touring while retaining the factory adaptive suspension with the KW Suspension Height Adjustable Spring Kit. Engineered and manufactured in Germany, the KW HAS system combines vehicle-specific lowering springs with adjustable spring perches, allowing ride height to be fine-tuned without replacing the factory dampers.

Unlike conventional lowering springs that provide a fixed ride height, the KW HAS kit offers continuous height adjustment within the approved lowering range. This allows owners to achieve the desired stance while maintaining compatibility with BMW's factory adaptive suspension, including electronically controlled dampers.

Each kit utilizes premium chrome-silicon steel springs developed specifically for the G90 M5 and G99 M5 Touring. Spring rates are carefully matched to the factory suspension characteristics and vehicle weight, delivering a more direct driving experience while preserving the balance engineered into the original suspension system.

The complete kit includes vehicle-specific threaded spring perches, elastomer bump stops, and dust protection components. The trapezoidal threaded adjustment system allows precise ride height changes while retaining the factory dampers and electronic suspension functionality.
