    Performance Handling. SR Performance's Sport Lowering Springs are an excellent way to improve the handling performance of your S550 Mustang. These Sport Springs will lower your Mustang's center of gravity, which will reduce squat during acceleration, body roll in the corners, and excessive nose-dive under hard braking. SR Performance Sport Springs are perfectly suited for daily driving, street, and occasional track applications.

    Aggressive Muscle Car Stance. Not only does a set of SR Performance Sport Springs improve the handling performance of your Mustang, but they also improve its overall appearance by lowering the ride height approximately 1.2-inches front and 1.0-inches (Fastback) or 1.2-inches (Convertible) rear eliminating that huge tire to fender gap, for a more aggressive street stance.

    Progressive and Linear Spring Rates. SR Performance designed their Sport Lowering Spring kit with progressive springs up front and linear springs in the rear. Progressive springs (also known as variable rate springs) provide a smooth ride with good handling characteristics when pushed hard. While linear springs have a constant spring rate allowing for optimum traction at low and high speeds.

    Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your factory size wheels and tires, as well as AmericanMuscle's pre-configured wheel and tire combo kits (specific to your generation), to assure proper clearance with no rubbing issues.

    Professional Installation Recommended. Seeing that a spring compressor is required for installation of these Coil Springs, AmericanMuscle recommends professional installation. With the proper tools, installation can be completed in about three hours. Please note that an alignment is highly recommended after installation.

    Application. This set of four SR Performance Sport Lowering Springs are specifically designed for use on 2015-2019 coupe and convertible Mustangs equipped with independent rear suspension (IRS), including the V6, EcoBoost and GT models. Does not fit Shelby GT350 models.

    Technical Note. These Springs are not compatible on vehicles equipped with the MagneRide Suspension System.

        Will these springs affect/change the driving modes (sport /track/snow...) on my Mustang GT?

        • The SR Performance Sport Lowering Springs will not affect the Mustangs drive modes since most of the ride quality change is produced from the shocks/struts.

        It looks like the difference between these and the SR Performance Lowering Springs is that these lower 1.2 inches in the front instead of 1 and the rear springs are linear, correct? Any other differences? Thanks. 0 answer
        What lower springs will work with a 2019 Gt that has performance pack? Was looking into the Eibach Pro Kit or Sportlines, but neither seem to work with the performance pack GT. And what does the performance pack have that causes the issue? thx wes 1 answer

            Perfect low

            I picked up a used 2018 Mustang and love it but it needed to be lowered. Now I'm not a young kid anymore, my wife reminded me when I started talking about this, so I didn't want it slammed to the ground. I wanted to keep the ride quality and not have to hear from her every time she rode in it or drove it. So, after reading all the reviews and watching the videos I went with the SR Performance springs. They are amazing. I If you want a slammed car I would look at something else but if you want to get rid of the wheel gap and keep the ride this is the way to go. You can't really tell a difference in the ride.

            Worth it definitely

            The springs add a really nice drop. convertibles will have a lower drop in the rear. the rear install is simple but compressing the front springs then putting them on turned into an amazing hassle ive never had with springs before on any other car. Overall definitely worth the cost and they handle really well but bewarned going over big bumps at speed will shake your internal organs.

            2017 GT Lowering Springs

            Very happy with the product, exactly what I was looking for. Dropped a little over an inch in the front and maybe .5-.75 inches in the rear. Car sits slightly lower in the front now. Ride is slightly stiffer than stock but feels great. Quality of the coating is good, looks better than the stock springs.

            Best mod so far

            Ride quality is much better, car sits way lower than expected. I did swap out tires and wheels at he same time so its a huge difference. If you are looking for a big time bang for the buck do this swap.

            Just right.

            Handles better with less body roll, especially with SR Performance Strut Bar - car looks lower and longer as well. Great price and everything fit perfectly - make sure and get the strut compression Loan-A-Tool at Auto Zone or equivalent.

            Best bang for your buck

            I own a 2018 performance pack Mustang. I wanted the lowered look and better handling experience but didn’t want to drop the car too low or drop a lot of money into coil overs, well at least not yet. These did the trick; its amazing how much just a one inch drop makes in the stance of these cars. The Eibachs and many others lower 1.2 and so on but are almost double the price( nothing wrong with those, they look great) but I wanted a combo of all of the above. Quality, performance and price...and that’s what I got. Ive had them on for a few weeks now and no problems, noise or etc. Great buy.

            Lil drop

            I ordered these hoping for the proper rake and got the exact look I wanted. These springs paired with 25mm spacers at all 4 corners is the perfect combo. Just over an inch drop up front and 1 inch in the back. It handles great and nearly eliminated the body roll and the heavy squat in a launch. No they aren’t for racing but perfect for my application and appearance. Another great product from SR performance and AM.
