      Video Review & Installation

      Hey guys, Stephanie with americanmuscle.com, here with my review and an install of the Roush Single Adjustable Coil Over Kit available for all 2015 and newer S550 Mustangs. In this video, we're gonna go over a few different topics with this coil over kit. But mostly, we're gonna talk about the performance abilities of the kit and the install. Gonna cover the install in more detail later, but I'll tell you right now that this install is straightforward but it is a little bit of work. So I'm gonna call it a two out of three wrenches in the difficulty meter.

      Race-inspired Handling. Dramatically improve the handling performance of your S550 Mustang with a Roush Single Adjustable Coil Over Kit.

      Adjustable Ride Height. Lower your S550 Mustang's stance and center of gravity from 0.8" to 1.5" up front and 1.0" to 2.0" in the rear for drastically improved cornering and handling with this Roush Performance Coil Over Kit. The coil overs come set to a 1.5" drop in front and 1.0" drop in the rear, but can be adjusted with the included tools to the desired ride height.

      Pre-Set Damping. Roush Performance engineered their Single Adjustable Coil Over Kit with pre-configured damping and spring rates for the ultimate balance of comfort and sporty race-inspired driving straight out of the box. This Roush coil over kit has been rated at producing over 1.0g lateral skid pad acceleration.

      Application. This Roush Performance Single Adjustable Coil Over Kit is specifically designed for use on 2015 to 2021 Fastback and Convertible Mustangs that is not equipped with the MagneRide Suspension.
