BMW 340i Coilover Suspension Kit - Dinan - Supplemental Ride Quality & Handling Kit - '16-'20 is the ideal companion to Dinan performance spring sets on the F30 340i. It refines ride quality and sharpens handling by optimizing bump travel on lowered cars.

This kit adds tuned, progressive-rate bump stops made from OE-quality material to maximize usable suspension travel, reduce harsh bottoming, and let the springs work effectively. When paired with Dinan springs, it rewards the chassis with improved mechanical grip and more predictable cornering, without unnecessary harshness. Includes four bump stops. Standalone installation is typically 7.8 hours (RWD) or 8.2 hours (xDrive); install time is negligible when performed with the corresponding Dinan Spring Set.
