KW H.A.S. Height Adjustable Spring Kit for 2008-2013 BMW 1 Series M and M3 (25320057)

Fits 2008-2013 BMW 1 Series M and M3 Base models.

The KW H.A.S. (Height Adjustable Spring) kit provides a performance-oriented alternative to conventional lowering springs, allowing you to fine-tune your vehicle's stance without sacrificing the functionality of your factory suspension. Unlike static springs, this system uses threaded KW height adjusters to provide continuous ride height adjustment even after the kit is installed. This allows for millimeter-precise corner balancing and aesthetics while retaining the use of factory electronic or adaptive damper controls.

Every H.A.S. kit is engineered with vehicle-specific spring rates developed through extensive testing at the Nürburgring Nordschleife and the KW 7-post driving dynamic test center. The springs are manufactured from high-strength, multi-coated chrome-silicon steel for maximum longevity and consistent performance under high wheel loads.
