Dinan's Performance Spring Set uses carefully calibrated rates to reduce body roll and lower the car for improved suspension geometry and a more aggressive stance. Each spring is CNC wound from high tensile chrome silicon wire, shot-peened for stress relief, and preset to prevent sag. Front stiffness increases by up to 95% and rear by up to 92% on the 330i depending on stock configuration, while the M340i and M440i xDrive receive targeted rear rate increases of 10 to 23%. The set drops ride height by roughly 5/8 to 1-1/8 inch depending on model and stays compatible with both conventional and factory electronic shocks.
