Dinan Performance Spring Set -BMW M5 2003-2000

E39;<br><br>Dinan's Performance Spring set for the E39 M5 provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the vehicle by 1/4 in. in the front and a 1/4 in. in the rear 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. The increase in stiffness of the springs 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.<br><br>For use with matching Dinan Koni Struts and Shocks for best results in addition to the Dinan Ride Quality and Handling Kit.<br><br>NOTE: Dinan Performance Spring sets should be purchased and installed with the corresponding Ride Quality and Handling Kit to achieve the advertised ride height performance and ride quality. While not explicitly required, if the matching component is not purchased and installed you will get less than favorable results in the form of poor ride quality and improper handling traits.
