KW H.A.S. Height Adjustable Spring Kit for 2015-2021 BMW M2, M3, and M4 (253200ANU)

Fits 2015-2021 BMW M2, M3, and M4 models including Base, Competition, CS, and GTS trims.

The KW H.A.S. (Height Adjustable Spring) kit provides a versatile alternative to conventional lowering springs, giving you the ability to fine-tune your vehicle's ride height even after installation. Unlike fixed-rate lowering springs, this system uses a threaded height adjuster to achieve the perfect stance without replacing your factory dampers. This ensures that all OEM driver assistance systems and electronic or adaptive suspension features, such as BMW's Adaptive M Suspension, remain fully functional and integrated.

Engineered specifically for the BMW F8X chassis, each kit features high-tensile springs made from multi-coated chrome-silicon steel. KW engineers have tuned the spring rates to work harmoniously with the original equipment (OE) damping characteristics and wheel loads, improving steering response and agility while maintaining ride comfort. The kit includes vehicle-specific elastomer bump stops and a dust protection system to prevent premature wear on your factory suspension components caused by road grime and debris.
