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 2015-2017 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.

If my mustang already comes with the stock manufacture spoiler, will I have to drill more holes? If so how many more?

AngelC

  • The GT350R Style Spoiler will require 8 holes to be drilled. It does not reuse the factory spoiler mounting holes.

Hi, I have a '17 premium GT w/the decklid spoiler and am aware that the holes would be exposed if I went to this. Is there some way to plug the exposed holes, rubber grommets perhaps?

Phil4Stangs

  • Hello! A few common ways that people solve the issue are: 1) Having a body shop fill and paint the holes. 2) Cutting a piece of rubber (like a grommet) so that it fits snugly in the hole. While I personally recommend that it be done by a professional, it is totally up to you!

    Best s550 spoiler by far!

    As soon as my boss's '16 R-code Shelby showed up, I immediately fell in love with the spoiler. Ford nailed a high spoiler that actually compliments the body lines of the s550. The downside? Ford's $6k carbon fiber price tag. Now thanks to this, I can enjoy it too! Only complaint is a bit of flexing/wobble at higher speeds. Everything is tighten down, due to the design, it's just not as sturdy as the true carbon fiber version by Ford, since their isn't a rigid backbone for support. Definitely still a great buy!

    A must!!!

    A great alternative to the gt350r carbon fiber spoiler. Same design same look just different materials. The ABS is sturdy and doesn't flap on high speeds like others (Walmart). Really happy with the results and to save some money for another mod.

    really good product for the price

    love the spoiler! not the best at high speed but still worth the money! got it installed by professional but with all the instruction sent with the spoiler, anybody could've done it, but its a new car so did not want to take a chance since you have to drill new holes and hide some of the old ones

    Best Spoiler Choice for S550

    This spoiler arrived extremely well packaged and anyone who orders parts regularly knows that is a rare thing. I took it to my local paint shop and had it ready to install within 3 days. I installed myself in 3 hours, could have done it faster, but took my time triple checking all of the mounting holes and enlarging the holes slowly to ensure a clean install that look very professionally done and everything lines up amazingly well. I can't praise this spoiler enough, really sets off the car in all the right ways!!! Thanks AM for offering it at such a great price!!
