DINAN Performance Spring Set – BMW 340i (F30 2016–2018) 

Enhance your BMW F30 340i with the DINAN Performance Spring Set — precision-engineered to improve handling, stance, and responsiveness while preserving ride comfort. With carefully calibrated spring rates and a subtle 1-inch drop, this setup refines suspension geometry, sharpens steering response, and reduces body roll for a more composed and confident drive.

As with all DINAN suspension systems, the design philosophy ensures performance gains do not come at the expense of ride quality. Pairing these springs with the Dinan Ride Quality and Handling Kit maintains proper suspension travel and ensures comfort remains close to factory levels.
