      Review & Installation Video

      Justin: If you're looking to help emulate the same styling found on one of the baddest Mustangs of all time then the SpeedForm GT500 Style Spoiler here would be a must-have addition for your 2010 through 2014 Mustang. The SpeedForm option will combine a durable yet lightweight ABS plastic for the build while also incorporating that pre-painted finished to perfectly match just about any color S197 there is. Price point is gonna hover right around 300 bucks and the install according to the site will get a two out of three wrenches on the old difficult to meter and take a couple of hours to complete from start to finish as we'll show you guys later in the video.So in my humble opinion, this is one of the best-looking spoilers out there for the 2010 through 2014 cars as it just balances the right amount of aggressiveness while still maintaining a little bit of that OE feel. Now I might be a bit biased here as I do have it installed on my S197 at home, but honestly guys, I have no intention of taking that thing off anytime soon as it really just kinda completes the rear end of the car.But as we mentioned earlier, the inspiration behind this particular spoiler is pretty clear, right? This one is obviously modeled after the same spoiler used on the mighty S197 Shelby GT500 and does feature the same styling cues like the same basic overall shape, same kind of rake coming off the deck lid and then finally your little detail towards the rear of the spoiler here. Now unlike the factory Shelby GT500 which does feature a black gurney flap in this location, the SpeedForm is just kind of paint match this portion to the rest of the spoiler. However, if you're a little creative and handy with paint or Plasti Dip, you could always black out this portion here as I have with mine at home.Materials are gonna be pretty standard here for the spoiler as you're looking at a pressure molded ABS plastic for the overall build before being painted in our in-house state-of-the-art paint booth here at AM. Now if you guys didn't know our AM team sprays the same base and clear coat that Ford uses on their Mustang so you guys can expect a damn near perfect color match for your ride right out of the box. As always, guys, not a bad idea just to double-check the paint code on the site and the availability before pulling the trigger. And hey, while you're there, feel free to read up on the numerous five-star reviews with this product and check out some of the customer submitted images to get a better idea of how the spoiler will look on your ride at home.One thing to note here, gang, is that SpeedForm states that the spoiler is not, I repeat, not compatible with cars equipped with a factory backup camera, so just be mindful of that before ordering. Also, the SpeedForm spoiler will mount using the existing holes left by your factory spoiler. Now if you don't have a factory option installed on your car then you will need to drill, there's really no getting around that. But to give you a better idea of how the installation is gonna go down, here's a detailed walkthrough as promised earlier along with a quick tool breakdown.Man: The tools used for this install were quarter-inch impact driver, 10-millimeter socket, alcohol prep pads, a damp microfiber cloth, a Phillips head screwdriver, and a clip panel tool. So the first step to this install is gonna be to pop your trunk and to remove the 13 clips that hold the interior panel to the trunk lid. Next we're gonna use a 10-millimeter socket to remove the four factory nuts that hold the spoiler to the deck lid.With our hardware removed, we can go ahead and remove our factory spoiler. Now ours has been off a few times, so it came off pretty easily. You may have to deal with a little bit of 3M stuck to the deck lid and you can remove this with a plastic scraper, some adhesive remover, or an eraser wheel if you have one. Next I'm gonna use a damp microfiber cloth to clean the surface of the deck lid before I use my alcohol prep pads. And now I can use the provided alcohol prep pads to wipe down all the surfaces where the 3M is gonna make contact.Now I'm gonna start by peeling back the corners of my 3M tape before I stick it onto the deck lid. Now I can carefully place the spoiler onto the deck lid and line up my bolt holes. Now I'm gonna use a Phillips head screwdriver to install my supplied hardware. I'm gonna keep these screws a little bit loose so that I can pull off the backing from my 3M tape but I want to get them all started first so they all line up.Now I can slowly pull back the tape, make sure I have good adhesion, and then tighten up the rest of my screws. And now I can fully tighten out my screws. And now finally you can reinstall your inner deck lid panel. And that's gonna wrap up this review and install for the SpeedForm GT500 Style Spoiler for your '10 to '14 Mustang. Thanks for watching. And for all things Mustang, keep it right here at

        Just What I wanted

        The GT500 spoiler is perfect for my 2013 coyote. The part that takes the longest is removing the adhesive from the previous spoiler. Other than that this install is extremely easy and straightforward

        Nice paint match

        I just got this spoiler today and I must admit,I was a bit skeptical about the paint matching because of the overall age of the mustang (2010) but I couldn’t be happier. It really should give the back of my mustang a more aggressive look. The other positive is no drilling. The holes will line up with my factory spoiler that’s on there now. I’ll post a few pics once it’s installed. American muscle had this thing wrapped very tight for packaging so thanks to them.

        Great New Look

        I loved the new look of the gt500 style wing the color match was spot on the only thing that sucked was getting the glue residue off the the car which was about an hour for me but it was totally worth the hassle.

        Paint quality and fit was perfect!

        Just like every Pre painted part from AM the quality of the paint and the fit was perfect. Took no more than 15 minutes for me to install. Can’t ask for better. The spoiler is a great addition to the car. Guess that’s why this is the most popular aftermarket spoiler out there. Pair this spoiler up with a rear valence and your mustang will make every car that you pass jaws drop. Love this spoiler!

        NIce spoiler

        The color is a little darker than the factory Sterling Gray but its not real terrible. Also wish it was painted black where the Gurney flap would be. It would also be easier to install if they would use studs for mounting like the factory spoiler rather than screws going into threaded inserts. Very time consuming to remove the original spoiler.

        If you own a 10-14 mustang this is absolutely a must! The gt500 spoiler is much more aggressive than the stock spoiler.

        Very similar to the factory design. Paint matched well. Hardest part was the removal of the old spoiler's adhesive.

      5 Top Rated Questions

      Do the holes matchup if you have an existing spoiler? In the description it says that the existing holes will be covered by the wing and that drilling two new holes is required. When reading some of reviews, they don't mention having to drill new holes and that the wing is a good fit. Sorry im a little confused so my question is "Will I have to drill new holes after I remove the stock wing or will the existing holes match-up with the new wing?"

      • Yes they do match up. If you don't have an existing spoiler they have to drill the holes but it does come with a template to make sure they are accurate.

      Mustang rear spoilers my 2011 Mustang does not have a rear spoiler on it. what is needed to install the GT500 style spoiler on it? Does it come with a templet for drilling the holes in the deck lid? on a scale of 1-10; with 10 being very hard what is the level of the install?

      • Honestly, I don't think i would attempt drilling the holes. If you mess up you DO NOT get a second chance. If i were you i would take it to a reputable shop. I had a local shop quote me for $125 for the installation of a spoiler.

      I have a 2014 GT with track pack. The description says this spoiler doesn't work with the factory holes. What do I do in this case? If i need to drill new ones and plug the old ones, does the new spoiler cover the old holes from the stock spoiler?

      • It depends on the spoiler you currently have on your car. If it is the pedestal spoiler, that comes on the GT/CS, that has 8 holes and this GT500 spoiler will only uses 4, which leaves 4 holes open. If you have an OEM spoiler that comes on the track pack (just a lip), this spoiler will use those existing holes.

      Does the Gurney flap detach from this spoiler or is it molded in.

      • Unfortunately the gurney flap is molded into this spoiler. It does not detach. One more detail to take into consideration when you purchase your pre-painted part is that the flap will be the same color as the rest of the spoiler and will thus not be black.
