BMW 550i xDrive Suspension Kit - Dinan - Handling Kit - 2011–2016. Designed to pair with Dinan Performance Spring Sets, this supplemental kit refines handling and preserves ride quality on your lowered F10 550i xDrive.

The kit centers on carefully tuned, progressive-rate bump stops made from OE-quality materials. By maximizing compression travel, it helps reduce sudden bottoming on rough roads while optimizing the effective spring rate for predictable grip and confident cornering. When combined with Dinan springs, the package enhances control without sacrificing daily drivability. Installation time for xDrive models is approximately 9.7 hours and is typically minimized when performed with the corresponding Dinan Spring Set.
