AST Suspension Adjustable Lowering Springs are designed to give the BMW X3M and X4M a lower, more aggressive stance while retaining the convenience of adjustable ride height. Built for the F97 X3M and F98 X4M AWD platforms, this spring kit helps reduce wheel gap, improve the vehicle’s visual profile, and provide a more performance-focused suspension setup without converting to a full coilover system.
