KW H.A.S. Height Adjustable Lowering Spring Kit for 2022-2026 BMW M4 Base, Competition, CS & CSL (253200EK)

Fits 2022-2026 BMW M4 models, including Base, Competition, Competition xDrive, CS, and CSL.

The KW H.A.S. (Height Adjustable Spring) kit provides a dynamic lowering solution for your BMW M4 without the limitations of conventional fixed-rate lowering springs. Unlike standard springs that lock you into a specific ride height, the KW H.A.S. system features an integrated height adjuster that allows you to fine-tune your vehicle's stance even after installation. This system is engineered to work harmoniously with your factory adaptive or electronic suspension, ensuring all driver assistance systems and comfort features remain fully operational.

Each kit is constructed from multi-coated chrome-silicon steel, featuring spring rates specifically calculated for the BMW M4's OE dampers and wheel loads. KW engineers develop these vehicle-specific parameters through rigorous testing on the Nurburgring Nordschleife and the KW 7-post Driving Dynamic Test Center to deliver more agile steering response and improved handling without sacrificing ride quality.
