MMX Lowering Springs for F9x BMW X3 M / X4 M

MMX Performance’s Lowering Spring Kit for the F9x BMW X3 M and X4 M enhances both handling and appearance by lowering the vehicle by up to 30mm, front and rear. Designed specifically for these high-performance SAVs, the springs improve cornering response and reduce body roll by lowering the center of gravity — all while preserving ride comfort for daily use. The drop results in a more balanced stance and eliminates the factory rake and excessive wheel gap for a cleaner, more aggressive look. Finished in MMX’s signature metallic grey, the springs are compatible with both passive and adaptive suspension systems, offering a straightforward, performance-focused upgrade for any X3 M or X4 M owner.
