Dinan's Performance Spring set for the G30 M550i 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 increase in stiffness will reduce the rear suspension compression under acceleration and front suspension compression (or dive) under braking, giving your car a more controlled feel. The Dinan performance springs will also provide a noticeable improvement in grip for high-speed driving situations that will inspire confidence in your car's capabilities. The reduced body roll makes the steering more responsive to driver input and will be noticed at low speeds up to the top speed of the vehicle.
