AST F97 X3M / F98 X4M Adjustable Lowering Springs

Upgrade the stance, handling, and adjustability of your BMW X3M (F97) or X4M (F98) with the AST Adjustable Lowering Spring Kit.

Whether you’re dialing in track settings or personalizing street ride height, these springs adapt without replacing your suspension.

Built for compatibility with factory adaptive dampers and driver assist systems, AST’s proprietary design maintains the full functionality of your BMW’s comfort and safety features; no compromise.
