This GT350R Style Spoiler not only enhances the appearance of your S550 Mustang, but it will also enhance its aerodynamics as well. SpeedForm's GT350R Style Spoiler will be sure to set your Pony apart from the rest of the herd.

    Superior Quality. Manufactured from blow molded acrylonitrile butadiene styrene (ABS) material, this GT350R Style Rear Spoiler was made to OEM specifications for a perfect fit. ABS is an extremely strong material known for its light-weight, superior durability and impact resistance. Unlike some other rear wing options on the market, this GT350R Spoiler won't chip or crack like fiberglass and will last for many years to come.

All necessary hardware is also included to complete this rear end upgrade. If your Mustang is equipped with a factory spoiler, the original holes will be exposed after installing this GT350R Wing.

    Application. This SpeedForm GT350R Style Rear Spoiler is designed to fit all 2015-2019 Fastback Mustangs including the V6, EcoBoost, GT and GT350 models. It is not compatible with Convertible models.

    Technical Notes. This rear deck lid spoiler ships unpainted. AmericanMuscle recommends professional installation of all body parts. We also recommend test fitting these products before they are painted.

        5 Top Rated Questions

        Does it come with a template to drill holes if your mustang comes without a spoiler like mine?

        • A drilling template will be included with this spoiler.

        What color is it if its primed? Is it a gloss black? Also can it be left unpainted but installed? Thank you.

        • It would be a grey primer finish, this would need to be painted or at least clear coated for protection from chips and scratches.

        Helpful (1)

        Is this the same dimensions as the carbon fiber gt350 style also offered on AM? From pictures this one looks lower than the carbon fiber one and stock gt350r.

        • The SpeedForm GT350R Style Spoiler is different the the Carbon fiber GT350R Style spoiler, as that one is manufactured by Anderson Composites. The Anderson Composites GT350R Style Rear Spoiler is significantly taller in the center compared to the SpeedForm spoiler.

        If I have a factory spoiler (black accent package) will this use the factory holes? Or at least cover them up?

        • If your Mustang is equipped with a factory spoiler, the original holes will be exposed after installing this spoiler.

        Helpful (0)

        is there any way to cover the factory holes with another smaller spoiler that could go in the middle ?

        • You would have to get a spoiler that covers or reuses the factory holes, like this one - https://www.americanmuscle.com/mmd-v-series-prepainted-rear-spoiler-1516.html

            It was a good part but the only thing that was bad was the factor spoiler left two holes and are really noticeable

            This spoiler looks amazing!!! Definitely exceeds my expectation. It is built very well and does rattle or shake at high speeds (at least so far). Would recommend to any one.

            Very high quality spoiler

            This spoiler is a great addition to my 2017 mustang. I had it painted black and installed for under 300$ and looks phenomenal. It does not flex or wobble from what I can tell. I am happy with my purchase and worth every penny.

            The spoiler was exactly as described, and gives my 2017 Fastback a look that's a perfect balance between sassy and refined.

            Rear Spoiler

            Great quality product, would recommend professional spraying, colour matching and installation. On a 2 year old GT looks like it had been fitted at the factory.

            Cheap install if you know how to spray paint!

            Probably the most time-consuming part of the install is painting it. It actually turned out pretty good with spray paint. Also had to drill an extra hole from the bottom of the trunk lid for access, as you’ll see in the pictures. Minor inconvenience.

            Looks Awesome!

            I bought my car with the spoiler delete option because I didn't like the look of the factory spoiler. I saw this spoiler and knew it was the one. The spoiler comes well packaged and with a primer finish that is ready to paint. I had it at the paint shop the next day and the day after that it was ready to be mounted. Do yourself a favor and make sure the templates are positioned as exactly as you can make them and you will have no problems. Also, follow the directions and mount the pedestals loosely first, then attach the spoiler and snug it all down. I had it installed in less than an hour and it looks awesome. I haven't seen any flex, though I haven't exceeded 100mph with it yet. I highly recommend this spoiler to complete that performance look.

            Quality spoiler, looks OEM

            Great spoiler that comes well primed.. Does not flex at all, I was told it was a little difficult lining up the spoiler recommend using a jig made out of cardboard to line up the holes correctly.

            SpeedForm GT350 Style Spoiler

            I was looking for a spoiler to finish the appearance of the back of my S550 that complimented the overall appearance and more aggressive look than the OEM factory spoiler. The GT350 Style Spoiler completes the look and I was more than happy when I had it installed and saw how the lines of the spoiler followed the car's lines. Definitely worth the cost.

            nice spoiler but if you have the factory small spoiler get ready to pay over 400$$$ to have the holes filled and deck painted plus the 350$$ to have the spoiler painted it turns into a very expensive project.
