    Hey, guys. Stephanie with here with the MMD Ducktail Spoiler for all '99 to 2004 Mustangs, minus you '03 to '04 Cobras that are out there. The rear spoiler does ship unpainted, so it's safe for me to say that it's gonna look much better once it's properly prepped and painted. Obviously, a paint-match spoiler is gonna look a lot more flattering, and I will say that this obviously isn't a fully-prepped piece. There's really no prep work done to this at all, and you can see that there's some imperfections visible, since it isn't prepped. So just don't be surprised if you pull this out of the box, and it doesn't look show ready. The MMD Ducktail Spoiler has a little bit of a different design than the other aftermarket spoiler options for the '99 to '04 Mustangs. It's taking some styling cues from the infamous '03 to '04 Cobra, so it's gonna be a great option for those of you out there that are looking for that type of style for your Mustang. A lot of the other aftermarket options, when if comes to spoilers and wings, are either pedestal-type, which isn't really a true spoiler, in my opinion, or the real wings. A true spoiler, for me, maintains contact with the decklid all the way around it all the time. So I'd say that the pedestal types resemble more of a wing to me. So I'd say that the Ducktail spoiler is a real spoiler, the only real spoiler that's available on the site. So the Ducktail style just adds onto the decklid. It's contoured the same way as the decklid but just adds a little beauty to the back to make it stand out some. It reminds me of a wide body kit. It takes a stock body and adds on to it and accentuates it. One of the nice things about this spoiler is that it doesn't cover the third brake light on the top of the decklid. There's an opening in the spoiler that will leave this open and still visible. And, of course, there's an opening for the keyhole in the trunk lid as well. Another cool thing and something that I like about this spoiler is that it doesn't require any drilling for the install. And it comes with the fill plugs to cover the holes that are left by the factory wing. The design of the spoiler does not cover all the holes that are left by the factory wing. So there are six plugs that are given to fill these holes. Now, the '01 to '04 models, we'll need to use two of these plugs. While the '99 to 2000s, we'll need to use all six of them. The factory holes are actually a decent concern when you start making changes like this, so it's nice that the fill plugs are included. You don't have to worry about rust or water leaking. As far as materials, this is an ABS material, which is a common material to use for exterior modifications. It's commonly used because it's lightweight and very durable, so it'll hold up through all kinds of weather and still maintain its looks. It's also impact resistant, so you won't have to worry about a fragile piece, and that's always a nice feature for street cars. When it comes to fitment, this rear spoiler is designed to fit the '99 to 2004 New Edge, so the V6, the GTE, the Bullet, the Mach 1, and the '99 to '01 Cobra. It will not fit the '03 to '04 Cobras. Now, the install is going be a little bit different, depending on where your car falls in the New Edge year range. The '01 to '04 models, we use a combination of both the 3M tape and hardware, using the existing holes left by the factory wing. That's why you only need to use two of the six fill plugs that are given. The spoiler installs using the 3M tape only on the '99 to 2000 models. As far as price, you're looking at spending about $300 for this spoiler. You also have to keep in mind the cost of paint if you're planning on paint matching this. But the additional cost of paint is going to be a concern across the board with aftermarket spoilers and wings. If this is a bit pricey for you, you can check out some of the other options. When it comes to the install, this is a very easy install. I mentioned this earlier, but the install will change, depending on what year Mustang you have, but not by much. This spoiler installs mostly with double-sided tape, so there's always the rule of making sure the surface is as clean as possible before the install. Both alcohol prep pads and adhesion promoter are provided, so using both of those things will help create a solid bond for the 3M tape. The install should take less than an hour to complete, and it's gonna be a one out of three wrenches on the difficulty meter. Wrapping things up here, the MMD Ducktail Spoiler is a ducktail-style, rear decklid spoiler that's made from a durable, lightweight ABS plastic, that's both lightweight and hardy. It keeps the factory third brake light. You don't have to drill for the install, and the spoiler comes with fill plugs for the factory wing holes that are not covered or utilized for the new spoiler.

    Ducktail Styling. If you are envious of the intimidating styling cues of the 2003 SVT Cobra, than this Modern Muscle Design Ducktail Style Rear Spoiler is for you. This sleek, low profile MMD Ducktail Style Spoiler will add a clean, yet muscular appearance to your New Edge Mustang that will be sure to turn heads.

    Clear View of Third Brake Light. Some competitor rear spoilers are known to block the entire view of the deck lid mounted third brake light. This MMD Ducktail Spoiler provides a clear and unobstructed view of the factory third brake light, keeping you visible and safe.

    High Quality Construction. To ensure a perfect fit, this MMD Mustang Ducktail Style Rear Decklid Spoiler was designed using the original OEM CAD data from Ford. It is made from molded acrylonitrile butadiene styrene (ABS) material for its light weight, superior durability and impact resistance - making it perfect for the daily driven Mustang. This Rear Spoiler is shipped to you (or your body shop) unpainted. 

    No Drilling Required. The MMD Ducktail Style Rear Spoiler is easy to install. On 2001-2004 models, the spoiler attaches with a combination of hardware and 3M automotive bonding tape using the existing rear mounting holes left by the factory wing. On 1999-2000 models, the spoiler installs with 3M automotive bonding tape only.

    Fill Plugs Included. As the design of this MMD Ducktail Style spoiler does not cover all the holes left by the factory installed wing, MMD provides (6) plugs to discretely fill the stock holes. 2001-2004 models will use (2) of these plugs, where the 1999-2000 models will need to use all (6).

    Application. This Unpainted Modern Muscle Design Ducktail Style Rear Spoiler is designed to fit 1999 to 2004 New Edge Ford Mustangs, including the V6, GT, Bullitt, Mach 1, and 99-01 SVT Cobra models. Does not fit the 2003-2004 SVT Cobra.

    Technical Notes. This MMD Rear Spoiler ships unpainted. AmericanMuscle recommends professional installation of all body parts. We also recommend test fitting these products before they are painted.

    I hope to see a lens or something for that 3rd brake light issue. Its a cool addition but that clear access to a stock trunk mounted light makes it border line chessy. Please make simple insert to make it look OEM. Any lens on the way or I missed?

    Will this spoiler cover the factory holes?

    • The MMD Ducktail Spoiler - Unpainted (99-04 All, Excluding 03-04 Cobra) does not cover all holes from the factory wing mount. This spoiler does include fill plugs to cover the factory holes.  2001-2004 Models will use two fill plugs.  1999-2000 will use six fill plugs.

    I converted my 3rd brake light to a smoked led aftermarket. My question is, I believe that the bulbs are built in the brake light. Basically I'm not able to change the led if it goes bad. I noticed that it sits on top of the 3rd brake light, if the 3rd brake light was to go bad I would basically have to rip off the spoiler to replace the 3rd brake light.... correct?

    • Yes in order to replace your third brake light you will need to remove this spoiler.

      Looks fantastic

      The wing looked great. The shipping was very fast I got it within three days. Only complaint was that the black plastic block offs looked stupid so I filled the extra two holes and repainted my trunk lid and that it appeared that the wing was wrapped in bubble wrap before the primer had dried but it was easily fixed with a little blocking. When installing be very careful not to put the wing on without the holes being lined up or you will have to fight with it to get it properly positioned.

      Although it is costly, it only comes primed. I wish it came painted because I had it painted at a shop and that cost me even more. If you have the money it's a nice addition if not, save your money.
