    Improves Stance and Handling. Improve the handling and stance of your 2015-2019 S550 Mustang by upgrading to a SR Performance Sport Coil Over Kit. Featuring upgraded, heavy-duty mono tube shocks and coils, this Sport Kit will greatly improve your Mustang's cornering capabilities, while lowering its ride height for a more aggressive appearance.

    Adjustable Ride Height. Not only will SR Performance Sport Coil Overs improve the handling of your 2015-2019 Mustang, but they will also improve its overall appearance. This SR Performance Sport Coil Over Kit is ride height adjustable allowing you to lower your Mustang anywhere from 1 inch to 3 inch (front and rear) to eliminate that nasty tire to fender gap for a more aggressive street stance.

    32 Way Adjustable Damping. The SR Performance Sport Coil Over Kits use 32-way adjustable mono tube struts that have been specially tuned to match the included spring rates. The 32 clicks of damping adjustment allow the driver to dial in their preferred handling feel or desired ride quality from soft to firm to match their driving needs.

    Recommended Upgrade. Seeing that lowering your Mustang can effect its alignment and suspension geometry, which can cause uneven tire wear and poor handling, SR Performance highly recommends the use of a set of camber adjustment bolts - not included, sold separately. By installing a set of camber adjustment bolts along with your Coil Overs you will have the ability to get your Mustangs alignment back into spec.

    Bolt-on Design. SR Performance designed their Mustang Coil-Over Kit to be an easy, bolt-on conversion. There is absolutely no cutting, welding or modifications required for a simple straight forward installation.

    Application. This SR Performance Sport Coil Over Kit is designed for use on all 2015-2019 Mustang models that are not equipped with the MagneRide Suspension.

        What are the key differences between these and the SR Performance Height Damping adjustable coil overs? (Item 393986)

        • The SR Performance Sport Coil Over Kit is height adjustable and will have dampening adjustment via a hex at the top of the strut. The SR Performance Height & Damping Adjustable Coil Over Kit will have an adjustment knob at the top of the strut for easier adjustment. Additionally, 393986 will have higher (stiffer) spring rates than 402841.

        What would be the ideal height for a daily driver front and rear? I want to improve the performance and handling but not slam the vehicle to the ground.

        • While it all comes down to personal preference, in general a lot of people like a 1" drop for a daily driver.

        How big of a handling difference would 402841 over the 393986 for track purpose.

        • The SR Performance Height & Damping Adjustable Coilover Kit will have adjustable dampening on the shocks and struts, allowing you to further fine tune your handling further. How much this will effect handling will depend on the type of track setting, as well as how hard the car is being pushed, etc.

        What is magneride suspension.

        • MagneRide on the S550 Mustang is an adaptive suspension. The magnetic ride replaces the traditional dampers found on passenger cars with monotube dampers that are filled with magnetorheological fluid. Magnetorheological fluid, or MR fluid, is known as a smart fluid in that its properties can be controlled by applying electric current to it. Electromagnetic coils in the dampers apply the current according to conditions which are measured by various electronic sensors.The fluid in the dampers travels faster or slower depending on the amount of current applied to the coils. Less resistance gives a better ride quality. As driver input or road conditions change, the resistance of the fluid is rapidly adjusted which can stiffen or loosen the ride.There are no moving parts in the MagneRide dampers. With no moving parts, there is nothing to wear out. The MR fluid allows the shock absorbers to adjust almost instantly — 300 times faster than the blink of an eye according to the manufacturer. After reading how a traditional damper works, you can begin to understand how this will improve the Mustang’s handling capabilities in all conditions making it sharper and safer.

            Great for the money

            I’ve had these for roughly 2-3 months now and for the money you can’t get better options! The ride even lowered is pretty smooth!

            Amazing for the price!

            These coil overs are amazing for the price. They ride great and feel so much better than stock. I have it on the stiffest setting all around and it’s tight stiff but not overly harsh where you can’t daily it. The handling improvements were wonderful as well. These aren’t perfect though. For one my tires were touching the coil over very slightly in the front so i had to put 5mm spacers on. in the front my tires were also rubbing somewhere inside the wheel well it smelled like I was doing a burnout for the first few miles until it went away. I’m still confused on that because it appears that I have plenty of space. All of that was just minor stuff the big issue I had was when I was installing the rear shocks the shock hat I had (bought my car and it came with a steeda shock hat not stock) wouldn’t work with the nut that came with the SR shocks! The nut was the exact diameter of the hole in the shock hat where it slid right though so I couldn’t mount the shock. I ended up flipping the stock shock hat fastener upside down and was able to grab the threads on the SR shock. Probably not a good idea but it’ll be fine. Overall they’re good for the steal of a price.

            Great starter coils

            It clears all of the major requirements for coilovers. Awesome adjustability for height, camber and dampening. For any first time coilover owners, do realize your cost of alignment might go up and some sounds are to be expected. Took me about 5 hours on jackstands in my driveway/street.

            Worth it!!

            I’m totally satisfied with the cars new look, and the performance of these coil-overs. I had them installed at a performance shop though watching the install video I think I could have done it myself. The handling and stance are noticeably better! Great price for what you get.
