      Description

      Shelby GT350R Styling. Add the aggressive track appeal of the mighty Shelby GT350R to your very own Fastback Pony with this great looking GT350R Pedestal Style Rear Spoiler from SpeedForm. 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.

      Drilling Required. This GT350R Style Spoiler will require some drilling for installation, templates are included to help find the proper locations. 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 2015-2020 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.

        Love it!!

        I really love the look of this spoiler! It's bold without being to much! Adds a very aggressive look! Can be expensive! I didn't find any place that would paint it for less that $200. But i definitely think it was worth it

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

      5 Top Rated Questions

      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.

      Why won’t this fit a convertible

      • This spoiler is designed for the 15-18 Fastback models only. Unfortunately it will not work with your convertible due to some differences in the body of the vehicle.

      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.

      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.

      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.
