Dinan Performance Spring Set for BMW X3 M40i and X4 M40i (G01/G02) — Enhanced Handling and Lowered Stance

Dinan's Performance Spring set for the G01 X3 M40i and G02 X4 M40i 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. G01 / G02

• 25% increase in spring stiffness in front and rear
• Vehicle lowered 7/8" (22mm) in the front and rear
• Substantial reduction in body roll
• Preset to prevent spring sag
