Progressive Lowering Springs

The Steeda Progressive Sport Springs are a performance suspension upgrade engineered to enhance handling and stance for 2015 and newer Ford Mustang V6, GT, and EcoBoost models. By lowering the vehicle 1.125 inches in the front and 1 inch in the rear, they refine the center of gravity and suspension geometry to significantly reduce undesirable behaviors like nose dive during braking, launch squat, and excessive body roll. Constructed with progressive spring rates, the front springs range from 145 lbs to 225 lbs, while the rear springs range from 525 to 820 lbs. This design allows the suspension to remain compliant for daily driving comfort while stiffening as roll increases to provide sharper steering response and stability during spirited maneuvers. These springs are compatible with both coupe and convertible configurations and provide clear fitment for 20-inch wheels. It is important to note that these springs are specifically designed for 2015 and newer Mustang platforms. Owners should ensure compatibility with their specific sub-model to verify the correct application, as these components are specialized for the S550 chassis geometry.
