KW Height Adjustable Springs (HAS) Systems are a great alternative to conventional lowering springs. You no longer have to be satisfied with a fixed lowering height. KW HAS systems allow you to adjust the vehicle ride height with the KW height adjuster even after the kit has been installed. Your vehicle gets a more dynamic look with the KW height adjustable spring kit, and the steering behavior and response of the standard dampers become more agile. All driver assistance systems and comfort features of a factory adaptive or electronic suspension remain operational and work harmoniously with our vehicle-specific spring set up.
KW uses high-quality springs made of chrome-silicon steel with spring rates designed specifically for each respective OE suspension damper and wheel load. KW's expertise and engineering ensure the spring rates will pair perfectly with the different damper characteristics of your factory adaptive electronic suspension. Along with the use of high-quality materials and the included KW ride height adjustment mechanisms, our KW height adjustable spring kits always include the vehicle-specific bump stops with a dust protection system to protect your factory suspension against wear & tear caused by road grime and debris.
Similar to a coilover suspension, the KW height adjustable springs allow a continuous adjustable ride height within a tested range, something not possible with conventional lowering springs. The dust protection elements and spring perches included in the delivery, when applicable, are always adjusted to the maximum technically possible lowering, typically limited by the factory dampers. With KW height adjustable springs, a sporty driving behavior can be achieved without negative effects on driving dynamics of your BMW.
