Dinan's Performance Spring set for the G20 M340i, G22 M440i (xDrive) and 330i provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the car for improved suspension geometry and an even more aggressive stance. The Dinan springs are CNC wound with high tensile chrome silicon wire and shot-peened for stress relief to last the life of the car.
Fits: BMW M340i (G20), BMW M440i (G22). Confirm fitment with us before ordering.
