      Review & Installation Video

      This RTR rear spoiler is the same spoiler that comes from the factory on the RTR Mustang. It's similar to a ducktail-style spoil, so it's going to be a good option for those of you out there that are looking either for a little bit of that unique RTR styling, or for those of you out there that are looking for a flush-mounted spoiler that's more the middle of the pack when it comes to being aggressive. The MMD V Series and the CDC Outlaw are similar spoilers, but they're a little too extreme for some. So if you're looking for something a little less than those, but more than the factory spoiler or some of those toned-down options, the RTR here might be for you.This spoiler reuses the holes that are left by the factory Fastback spoiler, so there'll be no drilling involved or holes to fill if you have a Fastback with a spoiler. The install for this spoiler is easy, even if you're looking at having to drill. I'm going to call it a one out of three wrenches on the difficulty meter. You can expect to spend an hour on the install. The first thing that I wanted to talk about here is the materials. This spoiler is made from ABS, which is different than what we're typically used to seeing from the RTR rear spoiler. In the past, the RTR rear spoiler has been aluminum with a powder-coated finish. The new version here is made from ABS plastic with a matte black finish, and that actually gives a more consistent finish with absolutely no issues. This spoiler was designed as a direct replacement for Mustangs that came with the factory spoiler. It'll reuse the holes that are left by the stock spoiler. But in the case of the S550s without the stock spoiler or the convertible models, you will need to drill two holes in the decklid to install this. The holes in the factory decklid of the convertible models for the factory spoiler are different, and they're not going to line up with this spoiler. As far as styling goes, this spoiler sits right on top of the decklid, and it extends upwards. You'll see that it comes down and covers the decklid some, and then extends over the sides to cover the edges of the car. The spoiler's finish is not raw-looking at all. But if you wanted to, you could always paint this very easily, but most just leave it matte black. This does install with two nuts and some double-sided tape. When it comes to price, you can expect to pay about $400 for this spoiler. That's pretty similar to what you'd be paying for any other unpainted spoiler. There are a few spoilers that cost less, but they're a little more tame styling-wise. Roush offers this spoiler for less as well, and so does RK Sport and SpeedForm. The install for the spoiler is easy, even if you are looking at having to drill. I'm going to call it a one out of three wrenches on the difficulty meter. You can expect to spend an hour on the install. If you have a factory spoiler, the most difficult part would be removing the adhesive on the decklid from the factory spoiler. You need a ratchet and a 10-millimeter socket, and a drill and drill bits if you're looking at having to drill. There are two rubber grommets that will need to be removed in the bottom of the decklid. If you need to drill, you need to use the drilling template, and mark and drill your two holes. If you have a stock spoiler, you need to unbolt it and remove it.Keep in mind that it is installed with adhesive tape as well, so it might take a few minutes to get under this and remove the spoiler. Either way, stock spoiler or not, you need to clean the surface of the decklid, so the double-sided tape can bond well. Use the provided alcohol prep pads. I'd recommend test-fitting the spoiler first, then use the adhesion promoter. Place the spoiler on the car, and use pressure on the tape surfaces. After that, you're just looking at tightening the supplied nuts and reinstalling the rubber grommets. Wrapping things up here with the RTR rear spoiler, this spoiler fits all 2015 and newer S550s.

      Ready To Rock! If you love how Vaughn Gittin Jr. tricks out his signature Mustangs, you no longer need to simply yearn to own one. You can install some of the very same parts he uses on his Ford Mustang RTR. This is the same exact rear spoiler that is included as original equipment on the Ford Mustang RTR designed and developed by Vaughn Gittin Jr. Sticking up above the deck lid, this RTR Rear Wing features a modern, race inspired appearance, making it the perfect addition to your 2015-2020 S550 Mustang.

      Durable ABS Construction. RTR manufactures their Rear Spoiler from high quality acrylonitrile butadiene styrene (ABS). ABS is an extremely strong material known for its light-weight, superior durability and impact resistance - making it perfect to withstand the hazards of daily driven vehicles. This Spoiler is completed in a stealthy matte black finish for aggressive good looks.

      Drilling May Be Required. Designed as a direct replacement for Fastback Mustangs that came equipped with a factory spoiler, this RTR upgrade will instantly transform the rear end aesthetics. Those S550 Mustangs without a stock wing will be required to drill two holes in the decklid to accommodate the installation. The RTR Rear Spoiler is attached with two nuts and double sided automotive bonding tape for a secure fit. Convertible models equipped with a factory wing will not be able to reuse the factory holes, drilling will still be required for installation.

      Application. This Matte Black RTR Rear Spoiler is designed to fit 2015-2020 Mustangs, including GT, EcoBoost, V6 GT350 and GT500 models.

        Perfect for 2019 Mustang EcoBoost

        This fits perfectly in place of the stock spoiler. Re-uses two of the holes and completely covers the other holes. The hardest part of the install is removing the stock spoiler. NOTE: On the 2019 Ecoboost fastback the stock spoiler has 4 bolts. It took about 1 hour to remove the old spoiler and 15 minutes to put the new spoiler on.

        Great look, good price

        Provides a really tasteful look and some aggression in the back end. Really easy install took about 20 mins after the test fit to make sure everything was lined up properly even with the drilling you have to do. Just don't lose the nut and you'll be fine!

        Horrible Finish

        This is the worst piece I have ever bought for my car. Its full of mould marks, stress marks and rough edges. Theirs no way this can go on a car without refinishing it. Its not smooth and just a piece of regular plastic. Do not recommend, I cant believe it has so many high reviews

        RTR rear spoiler

        The install was short and sweet. The template given was spot on. Only thing I would change is for the template to be pre cut to save a few minutes.

      I have a 16 California Special, will this cover up the holes left from the stock Cali wing?

      • This spoiler will cover up any holes left from the CS/GT spoiler.

      Would this spoiler cover up holes drilled into the truck for spoilers like any gt350 style spoilers? example: SpeedForm GT350R Style Spoiler

      • This will cover any holes that were drilled to accommodate the SpeedForm GT350R Style Spoiler.

      Can the bolts be removed so the spoiler can be installed using only the 3m adhesive tape?

      • Proper installation of the RTR Rear Spoiler requires the use of the bolts as well as the 3M tape. Without the bolts, it would not be entirely secured to the vehicle.

      I plan on ordering a 202 Gt Convertible in early Jan.. They delete any spoiler when ordering a convertible.. Will this fit without hitting the antenna that they use on convertibles?

      • This fits convertible models just fine. The only thing worth mentioning relative to convertibles any are convertible models equipped with a factory wing will not be able to reuse the factory holes, drilling will still be required for installation.
