Product Description

The KW H.A.S. Height Adjustable Spring Kit for McLaren 650S and MP4-12C is a premium ride-height tuning solution that bridges the gap between conventional lowering springs and full coilovers. Developed by KW Suspensions, this kit allows continuous adjustment of vehicle ride height even after installation, giving you the freedom to dial in stance and suspension balance to your exact preference. Designed to work seamlessly with the factory adaptive or electronic dampers, the H.A.S. system improves handling dynamics, sharpens turn-in response, and elevates the 650S’s poised performance while preserving comfort and drivability. Engineered and tested with KW’s signature precision, it’s an ideal upgrade for enthusiasts seeking both improved aesthetics and enhanced behavior on the street or track.
