    Review & Install Video

    If you're the owner of a 2015 through 2017 V6 EcoBoost or GT Mustang and you wanna add some of that aggressive GT350 styling to the front end, well then MMD's GT350 Style Chin Spoiler here would be a great choice. Now, the MMD option will be made from impact-resistant thermoformed ABS plastic, and then finished off in a factory-like textured black finish for all around 250 bucks. Now, install according to the site will get a strong one out of three wrenches on the difficulty meter here, take about an hour or so to complete from start to finish as we'll demonstrate a little later in the video. Now, obviously there is a lot to like about that Shelby GT350, right? From high revving, flat plane 5.2 liter, the corner-carving suspension and finally the aggressive styling that really does help separate the car from some of the non-Shelby models. Well now, thanks to MMD and the chin spoiler here, you can add a small piece of that aggressive front end styling without having to change out the entire front fascia.Now, material-wise, you're gonna find a very similar build to that of your factory chin spoiler, and that is this black-green texture material, which is sure to flow very well [inaudible 00:01:16] other factory plastic already present on your S550. Now, outside of the material, the spoiler itself was designed using original Ford CAD data, so it will certainly fit like a factory part as well. Now, the site will say this is also gonna help improve your aerodynamics once installed, but this is really more about appearance than an arrow park in my humble opinion. As far as what it's gonna do for your chin spoiler area, well as you can see, the side portion here is a lot more pronounced than the base car and even the performance pack chin spoiler. So, just be prepared for something that's gonna make a whole lot more of an impact visually. Now, speaking of fitment, I have seen a few questions in regards to the belly pan and performance pack in non-performance pack cars.And here's what I can say on that issue. If you have a non-performance pack car, well then your install is really not gonna be anything out of the ordinary and it shouldn't involve any modification whatsoever. However, if you do have a performance pack car with a slightly different belly pan, then there might be some minor modification needed to the belly pan itself as a few of those attachment points will be a bit different. However, to give you a better idea of how this will all go down, here's that detailed walkthrough we promised you earlier, along with a quick tool breakdown.The tools used on this install were a quarter-inch cordless impact, a 7-millimeter socket, a clip removal tool, a small flathead screwdriver, and a quarter-inch ratchet. So, the first step of this install is going to be to get underneath the vehicle and remove the belly pan that you can see right behind me. There are about 20 screws and a handful clips that need to be removed to pull the belly pan down so that you can get access to the back of the bumper where the chin spoiler is located.Next, I'm gonna remove the handful of push clips that hold the belly pan to the bottom of the car. Next, I'm gonna remove the 18 screws that hold the chin spoiler to the front of the bumper. Now, with all the screws removed, you can pull on the whip and remove it from the bumper. So, if your Mustang is a performance pack equipped Mustang, you're gonna need to remove the inner structure from the back of the chin spoiler. In order to do this, there's just a couple of retaining clips that you have to pry out of the way and remove this structure from the inside and transfer it over to your new one. If you have a base model or an EcoBoost, you don't have to worry about this. Before you can throw this back onto the vehicle, you're gonna want to transfer the one retaining clip on either side of the chin spoiler over to your new one before you can throw it on. Now, you can install your new chin spoiler onto the back of the bumper.Make sure to line up all the bolt holes, so you put your screws in when you're finished. Now, I'm gonna start installing all of my previously removed screws into the back of the chin spoiler. Now, we can reinstall the belly pan and wrap this install up.And that's gonna wrap up this review and install of the MMD GT350 Style Chin Spoiler for your '15 to '17 Mustang. Thanks for watching and for all things Mustang, keep it right here at

        I just ordered this but I forgot to ask... I have a 2015 GT Premium but not Performance Pack. I heard that it will fit but some bolts will not line up so I won't be able to use them?

        • This chin spoiler will work with the non-performance pack models just fine!

        Will the underside of this chin spoiler connect to the base model belly-pan, or the performance package belly-pan, with OEM fitment? The belly-pans connect to the bottom of the chin spoilers respectively. The performance package belly pan is larger so the bottom of the PP Chin Spoiler reaches back less, to connect, than the base model (vice-versa for the base model). I think this is what others have been trying to ask. Not so much as if it connects to the front bumper cover, but the under-pinnings of the car.

        • The MMD GT350 Style Chin Spoiler connects to the Front bumper as well as the factory splash guard on both Base and performance pack model.

        Is this shin spoiler compatible with SpeedForm Flip Down License Plate Holder - Motorized?

        • The MMD GT350 Style Chin Spoiler can be used with the SpeedForm Flip Down License Plate Holder, however the SpeedForm Flip Down License Plate Holder is a universal part, so the brackets will have to be played with and adjusted to get the right fit.

        Will I still be able to use the sto-n-sho front license plate mount? 1 answer
        The installation guide states that there are two versions of the splash shield (Track Pack and Non Track Pack). It goes on to say "...using the factory hardware reinstall the factory splash shield". It does not say anything about needing to drill additional holes. However, several people who have purchased this spoiler state that there are 3 side screws left over on each side that do not have holes for them to be screwed in. Something does not add up. Given a 2015-2017 GT Mustang Premium with the Performance Package (i.e. with Track Pack) will the installation require drilling of additional holes in the splitter or are ALL the holes pre-drilled? Please advise. Thanks! 1 answer

            Looks great But poorly engineered

            I really like the way it looks but I’m concerned about the poor fit on the belly pan. I have a 2016 5.0 base model and the new chin spoiler leaves a sizable gap where there’s nothing to secure the belly pan to on the new spoiler around the outer edges of the belly pan. It does look cool, but why not add I little bit more material to insure figment? Took about 2 hours to install by myself using floor jacks.

            Looks great, fitment is off

            The chin spoiler itself looks great and aggressive once it’s on the car. Installation however was a pain, took much longer than expected. Fitment and alignment is not very good, there is about a 3-4 inch gap on either side underneath on both sides of the chin spoiler from the splash guard so I’m not thrilled about that. But you can’t see it unless you get down and look under the car, and it does not seem to affect the anything so far so I will keep it on for now. The fitment on the ‘18-‘19 MMD chin spoiler seems spot on and is of better quality than this one. Again, this chin spoiler looks great but in my opinion is definitely not worth the $250 due to the fitment issue.

            Does not work with performance pack

            As another reviewer said, this is a $70 or $80 eBay part at best. Don't get me wrong, once on the car, it looks great! however, this does not fit the PP!!! Be prepared to reverse engineer your belly pan to work with this spoiler. I have several MMD parts and they are normally fantastic...this is a major let down.

            Money down the drain!!

            The spoiler itself fits the bumper just fine but when you try to put the splash shield back on it’s impossible. The spoiler does NOT work with the splash shield. Probably would not Recommend buying this spoiler unless they can figure out how to make everything including the splash shield fit right.

            1 2017 GT - USMCStang

            Don't waste your money if you have a PP Mustang

            This product will not pit the PP mustang since there is no way for the belly pan to secure on to. The description of the part is very misleading as it states that it will fit the GT. American Muscle also stated that the part would fit the PP mustang when ask the question as you can read in the questions and answers section. After calling customer service the answer I received was "it should fit your car" again stating it should fit the PP Mustang. After $100 dollars out of pocket to pay the shop that tried to install the part along with $10 that AM has now charged me to return the part I feel like I have been mislead by AM. AM needs to state which parts will and will not fit the PP Mustangs. Buyer beware when shopping from AM.

            Matches factory trim and looks good from the front, however its very thin and leaves about 6 fasteners on the splash shield open. Expected a more professional fitment and higher quality product for what i payed.

            May Require Engineering Degree

            The look of this chin spoiler is killer! However it may require an engineering degree to install. Once installed on the car, it was well worth the frustration. But that being said the fitment is far from OEM CAD data as the description says. The chin spoiler mounts up the the bumper just fine, but you'll start to run into problems when you go to reinstall the OEM Underbody Shield. This was mention in the reviews before I purchased the product. We ended up taking the OEM Chin Spoiler and mounting underneath the MMD Chin Spoiler, so that the Underbody Shield would have something to mount to. If you do not install both chin spoilers back on the car like this, you will not be able to secure the underbody shield and will more then likely have excessive flapping under the car at high speeds. I do recommend this product as far as styling goes, but the fitment could have been improved severely. Just be aware of what you're buying, and stay calm when installing this part. As in more then likely will not take only an hour to install...

            Really nice spoiler but had trouble with fitment.

            I was really excited to get this spoiler but unfortunately it didn't fit correctly on my 2015 Mustang GT Convertible. Let me be clear, it mounted perfectly with all the screws onto the car but it doesn't have that second layer on the outsides like the stock chin spoiler does so I had no where to mount the engine bay splash guard so I returned it. It looked really nice on the car so it was a real disappointment to have to return. It was amazingly easy to return to AM and they even paid for return shipping.
