DINAN PERFORMANCE SPRING SET - 2014-2021 BMW M235I/M240I (RWD Only)

Special Note: Not compatible with xDrive equipped cars.  Install time is 6.3 hours without alignment. Product Description Dinan's Performance Spring set for the F22 M235i/M240i provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the M235i/M240i by a 1/2" in the front and a full inch 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 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.   Benefits of the Dinan Performance Spring Set for the F22 M235i/M240i: + 10% increase in spring stiffness in front and 27% increase in the rear+ Lowers the vehicle 1/2" in the front and a full inch in the rear 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.
