KW Height Adjustable Spring (HAS) Kit - BMW M5 G90 2025-2026

The KW Height Adjustable Spring (HAS) kit replaces conventional lowering springs with a system that stays adjustable after installation, so ride height can be set to any point within the tested range using KW's height adjuster. Springs are wound from multi-coated chrome-silicon steel with rates matched to the factory adaptive dampers and corner wheel loads, and application-specific elastomer bump stops with a dust protection system are included. All factory electronic and driver assistance suspension functions remain fully operational.
