    Application. This SpeedForm GT350R Style Rear Spoiler is designed to fit all 2015-2018 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.

    Is there anyway you can take a picture of this wing next to a 2018 Performance package spoiler? Or let me know the dimensions, height etc etc. it looks very similar to the 18 PP spoiler minus the center supports. I’m trying to compare the two parts Thank you.

    What is the pros and cons between the material (ABS) of this spoiler vs the Anderson Composite spoiler (carbon fibre)? Resistance to cold/hot? etc...

    AndyN

    • Comparing the ABS plastic of the SpeedForm GT350R Style Spoiler vs the Carbon Fiber of the Anderson Composite Spoiler, the ABS plastic will be more affordable than the carbon fiber, which will offer a higher strength to weight ratio. ABS will be slightly more susceptible to the cold, however both materials have been shown to excel in automotive applications with no issues related to temperatures.

    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.

    Usaf1105

    • 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.

    how many holes are exposed and where are they if you choose to install this with the factory spoiler drill holes

    wesallen

    • When installing the SpeedForm GT350R Style Spoiler the factory holes cannot be used and new ones will need to be drilled. The factory drill holes will be exposed, I would recommend having them filled and have everything painted after fitting the new spoiler.

    If I have the stock spoiler on mt GT rn and drill my holes and install this spoiler will it cover up the holes from the stock spoiler or will they be exposed?

    wesallen

    • Yes, If your Mustang is equipped with a factory spoiler, the original holes will be exposed after installing this GT350R Wing.

    Hey guys, just wondering what the difference is between the SpeedForm and the other option you guys carry?

    • The SpeedForm GT350R Style Spoiler will be an ABS construction whereas the Anderson composites GT350 rear spoiler will be carbon fiber.

      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.

      Quality product But.......

      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.

      Nice...

      I kept going back and forth between this spoiler and the Type-AT Rear Pedastal Spoiler. I am very happy with my choice and I think my car looks fantastic with it painted to match my custom paint job and because it's custom I had my body shop install it since I would rather not mess it up lol. I haven't gone over 100 yet since having it installed but I can say there is no wobble or flex going at least 95 (that i can see). Well constructed!

      Super nice but left ugly holes in the middle

      I love how it looks but i would have thought about it twice if i knew there would have been holes left in the middle of it. I love the product just dont know hownto hide the old holes that were made from factory. With paint and removing old spoiler and installing new one. Took me a day to paint let it dry than another to remove and install

      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!!

      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.
