DINAN Performance Spring Set - BMW 550i F10 (11-16)

The DINAN Performance Spring Set for the BMW F10 550i refines both stance and handling while preserving daily comfort. With precisely calibrated spring rates and premium construction, this upgrade delivers flatter cornering, sharper response, and a sportier, more assertive appearance — all while maintaining OEM-like ride compliance.

Dinan’s approach to suspension tuning ensures that performance enhancements don’t compromise comfort. Each spring set is designed to work harmoniously with optional bump stops or ride-quality kits, maintaining proper suspension travel and geometry. The result is a suspension system that strikes the perfect balance between control, comfort, and aesthetics — the hallmark of Dinan engineering.
