      Review & Installation Video

      Hey, guys. Adam here with and today we're taking a quick look at and of course installing the MMD Chin Spoiler for the '05 to '09 Mustang GT. Now in my opinion, you can't be an '05 to '09 S-197 owner without picking up one of these chin spoilers from MMD. MMD is Modern Muscle Design and they're an absolute staple in the community of Mustangs. This category is flooded with exterior parts from MMD because they just look so good. This particular option from MMD is a super thick option. It's a little bit thicker and covers more area than some of the other chin spoilers out there and we know that there are quite a few for the S-197 at this point. This guy here goes from wheel well to wheel well and hugs perfectly. It's such a good, tight fitment around the front end. It almost looks like it could've come on the vehicle from the factory which has always been MMD's motive. They wanna make parts for your Mustang that stand out from the crowd while still looking like it could've come OEM.Now this guy is a thermoformed ABS plastic which is a nice, thick, very durable impact-resistant plastic. It's a textured matte black finish which blends in really well with the factory grille. This is not gonna fit your front bumper if you're a V6 owner. You'd have to pick up the GT front bumper or front fascia in order to get this guy installed.Now this one is gonna use 3M automotive bonding tape right around this section here, that top lip that goes under your bumper. It's gonna retain the two factory's Philips head screws in each one of the wheel wells to add some support. Now the install's gonna get one out of three wrenches on our difficulty meter. The price for this guy comes in right around a 150 bucks making it pretty affordable and really impactful for your front end and it'll take you about 30 minutes from start to finish to get installed. It's super simple. I'll walk you through the whole process. Let's get started.All right, tools used in this install include a knife, clean microfiber, soap and water mixture in a squirt bottle. I used the Philips head socket and a ratchet but a Philips head screwdriver works just as well.First step here. Grab a Philips head screwdriver and we're gonna remove the two Philips head screws on both sides in our wheel wells. Now there's not a whole lot of room here for a Philips head so I have my ratchet and a little Philips head socket. What we're gonna do is head in here with that 90 degree angle and get these off. Now if you don't have one of these and you only have a Philips head, you may either need to hop in the vehicle and turn the wheel all the way for both sides or remove the wheels all together.All right. Same thing on the other side.All right, so we've got our chin spoiler on the table here and what we're gonna do is take the 3M included in the kit. You'll get a roll of it. And we're gonna cut it out to the length that we need to stick it onto our spoiler. Now I've already precut them. They're not any specific length. You're just gonna measure out each little section here. I've put one on each side and then one right in the middle. So our longer strip that you see here, I'm gonna put in the middle. Now the spoiler actually installs like this. This is the bottom, here is the top. The 3M is gonna go underneath that top portion there and connect to your bumper under that lower grille. So we're gonna flip this guy over and focus on the top which is now on the bottom of the table. So let's take our longer strip. I'm gonna put it right about in the middle here going across. And so we're just applying that to that middle section and like I said, this isn't a perfect science so there's no specific measurement you need to measure out here. You just wanna put it where you see fit. I like to make sure there's one big portion in the middle and then little sections on each end.Now this one doesn't have as much of a surface area on the end so we're just gonna kinda roll up onto the top here. So you wanna keep it tight around the edge. If you go any higher here, it's gonna start to get toward the bottom of your bumper. You wanna keep it up toward the grille. All right, and then you're gonna do the same thing on the other side.So at this point we're gonna clean off the front bumper. Now this is a crucial part of the process. You don't wanna skip over it. I'm using a soap and water mixture in a squirt bottle and a clean microfiber. You can use a clean sponge, you can use clean microfibers, whatever you have. You just don't wanna use anything chemical heavy like Windex. You wanna make sure you're giving the 3M tape a really good bond with your factory paint. Now we're gonna use this crease here as our marker kinda cleaning on both sides of that. So I'm just gonna spray the vehicle and then take my clean microfiber and wipe her down.All right, so now we have the chin spoiler and what I did was I peeled off half of the backing on each 3M strip and draped it over the front like that. So when we apply it we'll be able to have it a little bit in place secured with some of the 3M that's hanging off and then we'll be able to position it where we want to. I'm gonna put one screw in in each wheel well to hold it in place and then we'll have easy access to peel off the rest of the back end.I'm gonna hook that around the front. Hold it in place. Put my screw in.All right, so it's a pretty snug fit so you wanna pull it over the edge like that and put it up into place and again, just put your screw through.All right, so the screws are kinda keeping our place where we know we want it to be on the ends. And then from there, you can take a look at the front end, position it where you need it to be. So this end's gonna come up a little higher. Then we're gonna press down and peel off the 3M tape excess.All right. Put firm pressure all around and now we can go back and tighten it down on each side.Same thing on the other side.So that's gonna wrap up my review and install for the MMD Chin Spoiler for the '05 to '09 GT and again, guys, this is gonna make a huge change to front end. Just adding a lot more of an aggressive, bold styling to your Mustang. Get yours exclusively right here at

        The MMD Chin Spoiler adds an aggressive note to mt 05 Pony. The look is impressive but not overbearing. I get a lot of compliments about the improved look versus stock.

        Looked good and easy install. I barely bumped a curb and it split. I will probably order another one and just be more careful

        The bottom of front bumper was starting to get wear and tear since I have had the car forever, and so far this front chin spoiler has been the perfect fix to it. It is sturdy as heck and will totally transform the front end. It is also super easy to install and took me 15 minutes!

      Hello, I bought a 2006 Mustang GT a couple months ago, super happy but want to do a little tasteful modding. I'm seriously considering this spoiler but am concerned about clearance. The previous owner lowered the car (not sure how much) and would like to know the dimensions of this product or its clearance on a factory height GT. Is it even worth getting if I may be scraping it on the pavement or worried about every little dip in the road? Thanks!

      • It's barely any lower than the stock bumper. You can get an idea of just how little in the install pdf. More than anything, it will protect your real bumper from more expensive to fix paint scrapes from contact that would have happened regardless.

      I have a 2009 Mustang GT/CS, V8 Motor. Will this MMD Chin Spoiler fit on this vehicle? It is very vague in other answers stating that it will not fit the GT/CS, and then others stating it will not fit the GT/CS V6.

      • The MMD Chin Spoiler is crafted for the GT bumpers only, and will not fit on a California Special model.

      Does anyone know if its fit GT bumper, i have a v6 but GT bumper. sure this is a dumb question but what the heck right.

      • This spoiler is designed to be attached to a GT front bumper. As long as the bumper is not modified where this spoiler attaches to, it will certainly work.

      Will this spoiler fit 2008 Bullitt?

      Will this chin spoiler fit with a lower billet grill?

      • The MMD Chin Spoiler will work with most billet grilles. We have not experienced fitment issues with any lower billet grilles we have tested.
