The Dinan D100-0934 Performance Spring Set transforms the ride quality, stance, and handling of the G20 330i/M340i and G22 M440i. Featuring calibrated rates to improve body control and reduce dive or compression under load, the springs lower the vehicle up to 1.125 in. while preserving ride quality. Spring rates are adjusted per model to maintain balance and grip, with up to 95% increased stiffness depending on stock configuration. The springs are compatible with both standard and electronic shocks, and are preset to prevent sag over time. For optimal results, Dinan recommends pairing with the matching Ride Quality and Handling Kit.
