Suspension systems that not only transform the stance of the vehicle but also maintain ride quality and improve upon handling are what Dinan suspensions are known for. This is accomplished by pairing spring sets with bump stops, spring perches or both to maintain suspension travel resulting in a smooth ride while also improving mechanical grip and handling. This is what makes Dinan suspension systems unique. While we can sell each component separately, it is highly recommended that both the spring sets and the supplemental ride quality and handling kits are used in tandem to maintain the Dinan quality standards our customers are used to. Experience the Dinan difference with this combination and enjoy the ride it provides.

Dinan's Performance Spring set for the F30 328i/330i (xDrive) provides greater control over body roll by carefully calibrated spring rates. Additionally, Dinan lowers the 328i/330i by 1" in front and 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 car's life. The 30% 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 improve 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 speeds as low as 20 mph up to the vehicle's top speed.

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 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 for improper handling ride quality traits due to not purchasing the corresponding handling kit will not be warranted.
