DINAN PERFORMANCE SPRING SET - 2015-2019 BMW X5M/X6M

Product Description 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. Dinan's Performance Spring set for the F85 X5M and F86 X6M provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the vehicle by a 5/8" in front and 3/4" 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 10% increase in stiffness to 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. NOTICE: 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. While we will maintain a full warranty on product defects, any claims against the car’s improper handling/ride quality traits due to not purchasing the corresponding handling kit will not be warranted.  Benefits of the Dinan Performance Spring Set for the F85 X5 M & F86 X6 M: + Decreased body roll from higher spring rates (10% increase in front)+ Lowers the vehicle 5/8" in front and 3/4" in the rear+ Shot-peened for stress relief+ Preset to prevent spring sag+ Compatible with factory electronic shocks and load-leveling systems Models Supported by Dinan Performance Spring Set for the F85 X5 M & F86 X6 M 2015-2018 X5 M F85  2015-2019 X6 M F86  Corresponding Ride Quality and Handling Kit highly recommended.Refer to description for details.
