Performance Handling. Installing a set of SR Performance Progressive Rate Springs will lower your S550’s center of gravity, which will reduce squat during acceleration, body roll in the corners, and excessive nose-dive under hard braking. SR Performance Springs are ideal for daily driving, street, and even occasional track use.Muscle Car Stance. Not only does a set of SR Performance Springs improve the handling performance of your Pony, but they also improve its overall appearance by lowering the ride height approximately 1.0-inch eliminating that huge tire to fender gap, for a more aggressive street stance.Progressive Design. Progressive springs (also known as variable rate springs) are designed to be more compliant when riding over rough and uneven surfaces like public roads. Progressive springs are engineered with a low starting spring rate that increases as the spring compresses. Variable rate compression allows for a smoother ride, while still providing good handling characteristics when pushed hard. This makes progressive rate springs a popular choice for daily street driven Mustangs.Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your factory size wheels and tires, as well as AmericanMuscle’s pre-configured wheel and tire combo kits (specific to your generation), to assure proper clearance with no rubbing issues.Professional Installation Recommended.
