    Review & Installation Video

    Review & Install Video

    Hey guys, Stephanie with, 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. This Roush Performance Coil Over Kit is designed to lower the center of gravity and reduce body roll for better handling that results in flat cornering and superior directional control — perfect for track days, autocross or a spirited drive down your favorite back road.

    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 2019 Fastback and Convertible Mustangs that is not equipped with the MagneRide Suspension.

        2 Top Rated Questions

        What is the overall weight spec for this coilover setup?

        • The Roush Single Adjustable Coil Over Kit weighs 69lbs as a whole.

        Helpful (1)

        When installing this kit is it necessary to also install adjustable toe links and camber plates to insure correct alignment can be achieved or did Roush somehow account for this?

        • The Roush Single Adjustable Coil Over Kit is height adjustable so depending on how much the vehicle is lowered, or what alignment specifications you would prefer you may or may not require caster/camber plates or toe links. We would recommend speaking with your alignment shop regarding how far your vehicle will be lowered, and if those components would be necessary for your exact set-up.

            Roush cool overs

            Huge difference in the way the car handles. Also added RTR tactical sway bar set, SR vertical links and Maximum motor sports caster/camber plates. Didn’t feel any loss of comfort and handle is beyond expectations.

            Rough coil overs

            This is a great suspension kit . Everything you need to install is in the box . I left my ride height at factory setting , these gave the car and great stance with a stiffer ride but still a good comfortable ride . The car lays flat in the corners with no body roll . It took a couple of afternoons to install but I was in no hurry because it's just a weekend car . I would recommend if you want to lower your stang and enjoy some corner carving . I liked these with ford performance sway bars and SR vertical links . Now it comes off the line great will no wheel hop and hugs the road

            A must have

            Handling is amazing. The car feels stable on the throttle and around corners. A huge improvement over stock.

            What the car needs!

            The install was quite easy really only take 6 to 7 hours with two people. I imagine the install could be faster, but take your time and the results will pay off. On the road you can fill a 100 difference and American muscle did a great job selling this product from Roush Performance. I recommend this over any other coilover product on the market. Roush has been at this race game for years and you can trust their dependable products.

            What the car needs!

            A good portion of the day install, the GT track pack/performance pack comes with very beefy suspension. Installing with roush coilovers wasn't hard, but it's best to have two people to help and also some stuff was torqued on very tight, so have a bar to help break them. Once complete the car felt glued to the road and felt so much better from the stock performance. I didn't expect to feel a huge difference, but the difference was easily noticed. Turned a few heads along the way.
