BMW X3M Coilover Suspension Kit - Dinan - Performance Coil Springs (2020-2025). A purpose-built upgrade for F97 X3M and F98 X4M that sharpens handling and refines stance without compromising daily usability.

Built around Dinan’s Performance Coil Springs, this kit increases spring stiffness about 20% front and rear and lowers the vehicle approximately 1 in. to enhance suspension geometry. CNC wound from high-tensile chrome-silicon and shot-peened, the springs are designed for longevity and are preset to resist sag. The higher rates curb squat under acceleration and dive under braking, reduce body roll, and make steering inputs feel more immediate. Compatible with the factory M Adaptive Suspension. For the advertised ride height, handling, and ride quality, Dinan recommends pairing with the corresponding Ride Quality and Handling Kit.
