BMW M550i xDrive Coilover Suspension Kit - Dinan - DIN CSS - 18-23. The DIN CSS coil spring set is engineered for the G30 M550i to sharpen handling and lower the car while maintaining everyday comfort when paired with the matching components.

Rates increase stiffness ~15% front and rear, lowering ride height about 0.75 in. for better geometry and less body motion. CNC-wound chrome-silicon springs are shot-peened and preset to resist sag. Results include less dive and squat, quicker steering response, and improved grip. For best results, add the corresponding Dinan Ride Quality and Handling Kit to maintain travel and achieve the advertised height and ride quality; without it, ride and handling may be compromised.
