Dinan Performance Spring Sets
Dinan Performance spring sets provide greater control over body roll via carefully calibrated spring rates. Plus, they lower your vehicle for improved suspension geometry and a more aggressive stance. Dinan springs are CNC-wound with high-tensile chrome silicon wire and are shot-peened for stress relief to last the life of your car. The increase in stiffness of the springs will reduce the rear suspension compression under acceleration, as well as the front suspension compression (or dive) under braking, giving your car a more controlled feel. The performance springs will also provide a noticeable improvement in grip, for high-speed driving situations that will inspire confidence in your car's capabilities. Use these performance spring sets in tandem with their supplemental ride quality and handling kits for the ultimate Dinan suspension experience.
