Overall it was a nice dual-purpose street and track package that raised the limits of the Mustang GT."

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.

For certain applications, higher than normal oil pressure is required. Typically, the oil pan must be removed to change the pressure spring on an oil pump. The Holley oil system allows direct access to the spring through the access port on the bottom front of the pan. Holley's high-pressure spring for Ford 7.3L Godzilla engines with their oil pump and pan can be purchased and installed to increase oil pressure by approximately 10 psi at higher rpms. To change the spring, remove the port plug, spring, and plunger. In some cases, the plunger may stay in the port. Make sure when reassembling the plunger is on top of the spring and oriented correctly.
