Product Description

Lowered Ride Height
Get rid of the ugly wheel gap on your S550 with the help of these 2015-2020 Mustang V6 or Ecoboost Eibach Sportline lowering springs! These springs lower your S550 on average by 1.5" in the front & 1.3" in the rear. The Sportline springs feature a linear rate for a more aggressive spring rate for additional handling benefits. It is recommended to use a performance shock and strut setup with this kit for maximum performance benefits.

Increased Suspension Performance
The Eibach Sportline springs were created for the extreme enthusiast who wants that "race-car" attitude for maximum street performance - with the lowest possible drop and the ride quality you expect from Eibach. Engineered with the same care as the Pro-Kit springs, Eibach Sportline springs achieve legendary handling by aggressively lowering the vehicle's center of gravity with precision-engineered spring rates.

    About This Brand

    Eibach - "The Will to Win"
    Eibach makes the finest performance suspension products in the world for your Mustang or Ford Lightning. When other suspension components sag, wear out, or create sloppy handling or a bone-crushing ride, top street tuners—like top race teams, from F1 to WRC, from Le Mans to NASCAR—inevitably turn to Eibach.

    Eibach integrates the exact same technology in their street springs as they do in their legendary race springs. Eibach uses the world´s finest Hi-Ten spring steel, produced to exceedingly precise tolerances. Eibach uses world-renowned German CNC coilers, as well as many unique machines engineered and built specifically by Eibach—simply state-of-the-art technology, in every step of the manufacturing process. Shop LatemodelRestoration.com for your Eibach Mustang lowering springs, suspension kits, and sway bars.
