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 springs 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 are able to 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 in order 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 G30 M550i provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the car 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 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 G30 M550i:
+ 15% increase in spring stiffness in front and rear.
+ Lowers the vehicle 3/4" in the front and rear.
To fully enjoy Dinan performance spring sets we highly recommend pairing them up with our supplemental ride quality and handling kits. This additional kit includes tuned, progressive rate bump stops that maximize suspension travel on the lowered car for improved handling capabilities and ride quality when compared to just a spring set. By allowing for full compression travel within the spring the possibility of a sudden "bottoming out" is negated, a common unwanted side effect when lowering a vehicle. Bump stops also have the added benefit of optimizing the spring rate rewarding those that use them with added mechanical grip and cornering power. Simply put, the Dinan supplemental ride quality and handling kits amplify performance and comfort when paired with performance spring sets.
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 Dinan 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
