BMW X4 M40i Suspension Kit - Dinan - Supplemental Ride Quality & Handling Kit (2018-2026). Purpose-built to complement Dinan performance spring sets, this kit refines ride and control on lowered X4 M40i models.

Engineered progressive-rate bump stops maximize usable suspension travel and curb harsh bottoming versus springs alone. Controlled compression improves ride on uneven pavement while supporting handling. Built from OE-quality materials and tuned for Dinan springs, the stops help optimize effective spring rate for consistent mechanical grip. Approximate install time is 9.9 hours when installed by itself on the X4 M40i; labor is minimal when combined with the Dinan Spring Set.
