AST Adjustable Lowering Spring Kit (ALS) Systems are a great alternative to conventional lowering springs. You no longer have to be satisfied with a fixed lowering height. AST  HAS systems allow you to adjust the vehicle ride height with the integrated height adjuster even after the kit has been installed. 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.

Similar to a coilover suspension, the AST height adjustable springs allow a continuous adjustable ride height within a tested range, something not possible with conventional lowering springs. With AST height adjustable springs, a sporty driving behavior can be achieved without negative effects on driving dynamics of your BMW.
