BMW X3 M40i Suspension Kit - Dinan - Supplemental Ride Quality & Handling Kit - 2018-2026. This kit adds carefully tuned, progressive-rate bump stops engineered to work with Dinan performance spring sets on your X3 M40i, refining control and comfort on lowered setups.

By maximizing compression travel, the stops curb harsh bottoming and keep the springs operating in their optimal range. The progressive design refines effective spring rate for improved mechanical grip and predictable cornering. Components use OE-quality materials and are purpose-built for the G01 platform. The kit includes four bump stops. Typical standalone installation time on the X3 M40i is about 9.9 hours; added labor is minimal when installed with the corresponding Dinan spring set.
