BMW 430i Coilover Suspension Kit - Dinan - Supplemental Ride Quality & Handling Kit - '17-'20. This Dinan add-on enhances ride compliance and control on 2017–2020 430i models when paired with Dinan Performance Spring Sets.

The kit swaps the factory bump stops for four tuned, progressive-rate pieces made from OE-quality material. Restored compression travel on a lowered chassis curbs harsh bottoming and keeps responses predictable. Rates are matched to Dinan springs for added grip and confidence. Standalone install: 7.8 hrs (RWD) or 8.2 hrs (xDrive); minimal when done with the matching Dinan Spring Set.

Features

• Includes four progressive-rate bump stops
