G01 / G02.
Suspension systems that transform the vehicle's stance while maintaining ride quality and improving handling are known for Dinan suspensions.
This is achieved 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 uniqueness defines Dinan suspension systems.
While each component is sold separately, it is highly recommended that both the spring sets and the supplemental ride quality and handling kits are used together to maintain the Dinan quality standards that customers expect.
Experience the Dinan difference with this combination and enjoy the ride it delivers.
Dinan's Performance Spring set for the G01 X3 M40i and G02 X4 M40i provides greater control over body roll due to carefully calibrated spring rates.
Additionally, Dinan lowers the car for improved suspension geometry and a 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 reduces rear suspension compression under acceleration and front suspension compression (or dive) under braking, giving the car a more controlled feel.
The Dinan performance springs also provide a noticeable improvement in grip for high-speed driving situations that inspire confidence in the car's capabilities.
The reduced body roll makes steering more responsive to driver input and will be noticed at low speeds 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 ride quality.
While not explicitly required, if the matching component is not purchased and installed, less favorable results may occur in the form of poor ride quality.
