      Aggressive Handling. For the serious driving enthusiast seeking an unmistakable race car feel, the Sport-Plus Suspension Kit from Eibach delivers. The performance springs and adjustable sway bars improve handling for better grip, especially during hard cornering. Plus, the lowered body of your Pony provides a more aggressive appearance both on and off the track. Whether you're installing the Eibach Sport-Plus Kit with factory or aftermarket performance dampers, it's been engineered and tested to deliver balanced handling precision.

      Lower Center of Gravity. This is key. With a lower center of gravity, you're going to reduce squat when accelerating, body roll when cornering and nose dive when braking. As the laws of physics tell us, lowering your car improves the aerodynamic properties of your ride, resulting in reduced drag and greater speed.

      Sportline Springs. Eibach's Sportline Springs feature a progressive rate that delivers maximum street performance, without compromising safety or ride quality. Designed to lower your S550 approximately 1.5" in the front and 1.3" in the rear, the extreme performance of these lowering springs is equally matched with exceptional style.

      Adjustable Sway Bars. Eibach fabricates their Front and Rear Sway Bars from cold-formed, aircraft-grade steel for high quality performance. The 35mm tubular front bar and 25mm rear bar are 3-way adjustable, which lets you fine tune your V6 or EcoBoost Pony to best suite your personal driving needs. Both bars are completed in a bright red powdercoat finish for superior looks and durability.

      Kit Components. The Sport-Plus Kit by Eibach includes front and rear Sportline lowering springs, front and rear adjustable sway bars, polyurethane bushings and all of the required hardware needed for installation.

      Clears Stock and Aftermarket Wheels & Tires. This Suspension Kit 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.

      Professional Installation Recommended. Seeing that a spring compressor is required for installation of these Coil Springs, AmericanMuscle recommends professional installation. With the proper tools, installation can be completed in about three hours. Please note that an alignment is highly recommended after installation.

      Application. This Eibach Sport-Plus Suspension Kit is an ideal upgrade for all 2015-2021 V6 and EcoBoost Mustangs that is not equipped with the MagneRide Suspension.
