Get rid of the ugly wheel gap on your S550 with the help of these 2015+ S550 Mustang Eibach Sportline lowering springs! These springs lower your Ecoboost or 3.7L Ecoboost on average by approximately 1.5" front and 1.3" rear. Eibach Sportline springs are progressive and feature 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.
