      Improves Handling Performance. If you're the hard driving Mustang owner that pushes their Mustang far past the limits of the factory suspension, you really need to upgrade to a Koni Shock, Strut and Eibach Pro-Kit Suspension Package. This Koni/Eibach Suspension Package will drastically improve the overall handling performance of your S550 Mustang. Designed as a bolt-on upgrade, the combination of Koni Adjustable Shocks and Struts with Eibach's Pro-Kit Lowering Springs will transform your S550 V6 or EcoBoost Mustang into a true track terror, all while maintaining satisfactory ride quality. A Koni Shock, Strut and Eibach Pro-Kit Suspension Package is ideal for spirited daily drivers that participate in track and autocross events.

      Adjustable Rebound Settings. Koni designed their Sport Shocks and Struts to be on car adjustable allowing you to adjust rebound dampening with just a twist of a knob. Turn the knob clockwise and soften the dampening, turn it counter clockwise and stiffen the dampening. On car adjustability is great for fine tuning your suspension rebound to match your driving situation, whether its street, performance or track.

      High Quality Construction. Koni's Sport Series Adjustable Shocks and Struts are a performance upgrade that feature a steel bodied, gas pressurized twin tube design with a larger-diameter piston for optimum street performance. Koni completes their Sport Series Shocks and Struts in a classic yellow finish with the world-famous KONI logo for corrosion resistance and exciting good looks.

      Eibach Pro-Kit Springs. Included in this suspension package are a set of Eibach Pro-Kit Progressive Rate Springs. These Springs are designed to lower your S550 Mustang's center of gravity, reducing squat during acceleration, body roll in the corners and excessive nose-dive under hard braking. Eibach's Pro-Kit Springs will also improve your Mustangs appearance. By dropping the ride height, these Eibach Springs will eliminate the lifted 4x4 factory look for a more aggressive street stance.

      Clears Stock and Aftermarket Wheels & Tires. This Koni/Eibach Suspension Package was engineered to be compatible with your stock 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.

      Application. This Koni Sport Adjustable Shock, Strut and Eibach Pro-Kit Suspension Package is designed for use on 2015 to 2020 V6 and EcoBoost Mustangs, including the Fastback and Convertible models. Does not fit Shelby GT350 or models equipped with MagneRide.

        Lower center of "greaty".

        this is just great since you are closer to the ground and it feels like you are siting on the road. Eibach products are the best. Very happy with it. Ride comfort is nice as well.
