    Review & Install Video

    Hey, guys. Stephanie with americanmuscle.com here with a review and install of the MMD GT350 STyle Upper and Lower Grille Extensions for the 2015 and newer S550 GT Mustang. In this video, we're gonna go over a few different topics with these grille extensions. We're gonna talk about the styling of these, the materials and construction, and the install as well. I'll go into more detail later, but I can tell you right now that the install for these is an easy one. It's a one out of three wrenches on the difficulty meter. The MMD GT350 Style Upper and Lower Grille Extensions are going to be something that you should check out if you're looking for a way to change the front-end appearance of the S550 GT, but you don't necessarily wanna shell out the cash for a complete new upper and lower grille setup since that can get expensive fast, or you don't wanna completely revamp your grilles. This would also be a good option for you if you're after adding some of that GT350 style to your Mustang. They're not gonna fit the 50th anniversary or the base model grilles. These grille extensions are just added to your factory grille, and MMD designed them to give a very close appearance to the GT350 grille. Now it isn't gonna look exactly the same, but you'll still get that very similar appearance. You're also changing the looks of the front-end of your car in a very simple, very easy, and also reversible way. That's the beauty of these, in my opinion. They're so simple, yet they do make a difference in looks, and you don't have to spend an arm and a leg or go with a completely after-market grille. You're getting both upper and lower grille extensions with this little kit here so that you can complete the look. These are made from ABS plastic, which is commonly used for exterior styling because it's lightweight, strong, and durable, and these are all good qualities for an item that's gonna be living on the front of your car. These are gonna come with everything you'll need to get them installed. Like I said, a big plus here is that they're very easy to install. They install with just 3M tape, that's already on the backside of the extensions so you don't even have to worry about placing it. They're also gonna come with alcohol wipes and adhesion promoter so you can make sure that you get a good bond. When it comes to price, you can expect to pay right about the $150 mark, which is less than half the price of any other grille option that you have. As far as the install, if you wanna even call it an install, it's very easy. It's a 1 out of 3 wrenches on the difficulty meter, and you can expect to spend 15 minutes to get these installed. You won't need any tools, but you are gonna wanna make sure that you have a clean surface and that you test fit the extensions before installing. And they are side specific, so just make sure that you have the correct sides ready. Once you have the grille clean, use the alcohol prep pads to prep the grille where the 3M will be. Then use the adhesion promoter after you peel the backing off the 3M tape, and allow it to dry. Then it's just a matter of firmly pressing the grille extensions onto the grille using even pressure. I would just keep in mind allowing these to set on the car before you wash it or take the car in the rain. Wrapping things up here with the MMD GT350 Style Upper and Lower Grille Extensions, these offer a fast and easy way to change up the looks of the front-end of the S550 GT without having to purchase an entirely new grille replacement. They will give your Mustang a touch of the GT350 styling. They allow you to keep the factory grilles, and you can check them out more online right here at americanmuscle.com

    Will these work with the California Special edition of the 2017 GT? I want to make sure they won't interfere with the off-center tri-bar Mustang logo.

    Can I install these on my bumper with the bumper off? I want to make sure they will stay so would like to use automotive adhesion on extensions to the grill. Let them dry, then install on the car. I want to make sure the grill extensions aren't so large the grill won't go back in. Thanks

    Hello, I have an european Ford Mustang GT Premium 2016. This part will fit with the upper grille. I have a doubt about the fitting with the lower grille of my EU GT. What do you think ? Regards Antoine

      Love the look!

      I fully expected these parts to be cheap feeling and be a poor fit. I couldn't have been further from the truth. They are strong and they fit so well that they look like the came with the grille. They really make the "fang" look of the stock grille stand out. Highly recommended!

      I was skeptical of this mod becouse of the cost, and it looks minor. But now that I’ve seen them and put them on I’m very very happy with the quality and end result, it looks significantly more aggressive in person! MMD GT350 Grille Extension MMD GT350 chin MMD fog light splitter

      They add a nice upgraded look to the S550. Combined with the black pony emblem and these there is no reason to get an expensive grille.

      My grill was hit by a flying piece of ice from a Semi Truck on I-70. Busted the factory grill extension. I bought these and they fit perfectly and covered the damaged one completely. Easy install and they look killer!

      GREAT AGREESIVE LOOK

      Great part to add to the GT grille. It definitely gives it the GT350 look. I have the GT Grille delete kit on mine so I had to cut off the tabs to make it fit so keep that in mind if you have the gt grille modified. I also added some additional tape and glue some of the plastic glue that I used for the grille delete kit since I cut the tabs off.

      They fit decent enough on a mesh grill.

      I purchased these knowing that I had a 50/50 chance of them working with my OE grill frame with aftermarket mesh. I did have to cut the tabs off, but other than needing to double up on the tape due to them not grabbing on both sides of the "fangs", they are on strong and look fantastic on my 2016 PP/GT!

      These pieces of plastic make the front of the car look "beefier" as they emphasize the "fangs". I just wish the contact points were a little less noticeable. Install, if you even want to call it an install =), is cake. I like!

      Look great

      These exts really made the front end of the car more aggressive looking without having to spend a ton of $. For one of the exts I had to add my own 3m heavy duty tape since it was loose when initally putting on.other than that they look awesome.

      Grille extension

      Would have loved to install these but they don't fit my car. If you have a California Special these extensions aren't for you. The grill on the CS is quite a bit different than the regular GT models. Unfortunately it's not mentioned in the description but these will not go on the CS model of the GT. I will be returning.

      Looks good, but moves around

      I installed just as directed. The pieces still moved around a bit independently of the grille even after things set several hours (may not be enough double sided adhesive tape). I dabbed a couple drops of super glue between the pieces and grille in conspicuous areas - now things are rock solid -

      Looks great!! but expensive for what you get.

      These extensions look great and really give the front end of my car a more aggressive look that is still OEM style and quality. Easy to install took about 15 minutes, everything you need is included. They are very solid if installed properly. Finish matches the OEM grille perfectly and the seams to the extensions are almost invisible. These are however very expensive for what you are actually getting, just four pieces of plastic and some 3M tape. But they look great and they are the only option like this, so I couldn't help but pay the premium. I am very satisfied, even with the high price.

      Just what I was looking for.

      Always liked the stock grill with the honeycomb look but it needed a little something. MMD figured it out for me, really complements the splitter I have and balanced out the front end for me. Extremely happy with this product, price and fit. I got their front bumper splitter to add next since I think these mods fit what I have very well.

      MMD- Makes My Day!

      I'm really happy with my purchase. Saw it on the new products page and was really curious about it. The stock pictures used don't do it justice; you'll have to see it in person to see the real difference! I just wish the top part of the grille stuck out a bit more. Other than that, excellent exterior mod!
