Description
Discover the Dinan Performance Spring Set for the G20 M340i, G22 M440i (xDrive), and 330i, designed to transform your BMW's suspension system for both aesthetics and performance. These springs are renowned for their ability to enhance the stance of your vehicle while preserving ride quality and improving handling. By pairing the spring sets with bump stops, spring perches, or both, Dinan ensures that suspension travel is maintained, resulting in a smooth and comfortable ride, all while delivering superior mechanical grip and improved handling.
What sets Dinan suspension systems apart is their commitment to quality. While each component can be purchased separately, we highly recommend using both the spring sets and the supplemental ride quality and handling kits together to maintain the exceptional Dinan standards that our customers have come to expect. This combination allows you to experience the full potential of Dinan's performance enhancements and enjoy the unparalleled ride quality it provides.
Dinan's Performance Spring set for the BMW 330i, M340i, and M440i (2019-2022) offers precise control over body roll, thanks to carefully calibrated spring rates. Additionally, these springs lower the car, improving suspension geometry and creating an even more aggressive stance. Crafted with CNC-wound high tensile chrome silicon wire and shot-peened for stress relief, Dinan springs are built to last the life of your vehicle. The increased stiffness reduces rear suspension compression during acceleration and front suspension compression (dive) during braking, resulting in a more controlled driving experience.
Furthermore, Dinan's performance springs provide noticeable improvements in grip, particularly during high-speed driving situations, instilling confidence in your car's capabilities. The reduced body roll enhances steering responsiveness to driver input, making a noticeable difference at low speeds and all the way up to the vehicle's top speed.
Please note that Dinan Performance Spring sets should always be purchased and installed with the corresponding Ride Quality and Handling Kit to achieve the advertised ride height performance and optimal ride quality. While not explicitly required, failure to purchase and install the matching components may result in poor ride quality and compromised handling. Although we provide a full warranty on product defects, claims related to improper handling and ride quality due to not purchasing the corresponding handling kit will not be warranted.
