DINAN Performance Spring Set – BMW M550i xDrive (2018–2023)
DINAN Performance Spring Set – BMW M550i xDrive (2018–2023)
Upgrade the handling and stance of your BMW G30 M550i xDrive with the DINAN Performance Spring Set, engineered for precise control, reduced body roll, and improved suspension geometry — all while maintaining ride comfort and drivability.
Each spring is CNC-wound from high-tensile chrome-silicon wire and shot-peened for stress relief, ensuring long-term strength and consistent performance. Designed with a moderate ¾" drop, these springs provide a more aggressive look and enhanced steering response without compromising everyday comfort.
The increased stiffness enhances grip, reduces squat under acceleration, and minimizes dive under braking, allowing the vehicle to feel more planted and confident in all driving situations. Pairing these springs with the corresponding Dinan Ride Quality and Handling Kit ensures proper suspension travel and optimal comfort — maintaining the standard of refinement that Dinan is known for.
