BMW 340i xDrive Performance Spring Set by Dinan (2016–2018). Precision springs that tighten handling and refine stance while preserving daily comfort.

Carefully calibrated rates give tighter control without harshness. The 340i xDrive drops 1.0 in front and 1.125 in rear for better geometry and reduced roll. CNC-wound, high-tensile chrome-silicon springs are shot-peened and preset to resist sag. With about 30% higher stiffness, they curb squat and dive, and work with both conventional and factory electronic shocks. For best results, pair with Dinan’s Ride Quality and Handling Kit; skipping it may cause poor ride quality or improper handling.
