BMW X3 M40i Coilover Suspension Kit - Front + Rear - Dinan - Performance Spring Set - 2018–2025. Dinan’s matched front/rear springs for G01 X3 M40i and G02 X4 M40i lower the car and sharpen handling.

Calibrated rates add control without harshness. Stiffness rises about 25% and ride height drops ~22 mm (7/8") front and rear. CNC-wound from high-tensile chrome-silicon, shot-peened, and preset to resist sag, they curb squat, reduce dive, and cut body roll for sharper steering. Includes two front linear-rate and two rear dual-rate springs. For intended drop and ride, pair with Dinan’s Ride Quality & Handling Kit (sold separately).
