    Review & Installation Video

    Review & Install Video

    Hey, guys, Stephanie with americanmuscle.com, here with a review and install of the MMD Rocker Panel Winglets for 2015 and newer S550, GT, V6, and EcoBoost Mustangs. In this video, we're going to go over a few different topics when it comes to these winglets. We're going to talk about the styling, the materials and construction, and the install as well. I'll talk more about the install later, but I can tell you right now that the install for these is easy. It's a one out of three wrenches on the difficulty meter, but there is some drilling involved.The MMD Rocker Panel Winglets are going to be a good option for those S550 owners out there that are looking to add just a little something to the side profile view of their Mustang. These can be added to completely stock Mustang to give a little something to the appearance of the car, or they can help tie together some other exterior mods. Either way, these offer you a fast and simple way to give your Mustang a change in appearance without having to purchase entirely new Rocker Panels or splitters, and they're going to be a lot less expensive in that case as well.These Rocker Panel Winglets are just added to your factory rocker panels. They install with push pins and they wrap up and around the factory rocker panels at the very end, right before the rear wheels and tires. MMD designed them to give you a change in looks on the side of your car, and a very simple, very easy, and also reversible way. And that's the beauty of these in my opinion. They are so simple, yet they do make difference in looks, and you don't have to spend an arm and a leg, or go with a completely after-market rocker panel or side splitter.When it comes to materials, these are made from ABS plastic, which is commonly used for exterior styling because it's lightweight, strong, and durable, and those are all good qualities for an item that's going to be living on the lower rocker panel of your car. They do have a matte black finish as well, which looks very much OEM-like. So, they are going to match and blend in with your factory rocker panels and not look out of place.These are going to come with everything you need to get them installed. Like I said, a big plus here is that they're very easy to install. They install with just the supplied push pins, three on each side. One thing that I did want to mention though, is that these are designed to fit the S550, GT, V6 and EcoBoost models. They are not going to fit the GT350.As far as price, you can expect to pay between $50 and $100 for these. Now if you compare that your other side splitter and rocker panel options, there's nothing that comes close to this price. MMD is giving you an option here for the budget minded people, but still giving you a way to change the looks of your car, which I think is a great thing.When it comes to the install, it's not a difficult one at all and it's going to be a one out of three wrenches on the difficulty meter. There is a little bit more to the install than just sticking these on and going. So, you can expect to spend an hour tops, getting these on your car. You will need some basic hand tools, because you're looking at needing to drill the factory rocker panels for the push pin retainers, and you're also going to need a jack and jack stands to get the car in the air.Now, I'd test fit your winglets before actually installing them, but once that's done, you can drill your three holes for the push pins, line up the winglet, and officially install it. Wrapping things up here with the MMD Rocker Panel WInglets. These offer you a fast and subtle way to change the appearance of the side of your Mustang. They're very easy to install and you can check them out more online right here, at americanmuscle.com.

    Could you flip these and swap sides to actually use up front as well? Would give a kind of GT350 feel?

      Mmd winglets, nice alteranative to entire rocker

      So, it said to adjust the closeness anyway you wanted. I decided to try and make it flush with the car, 1-it’s less likely to Rip off at high speeds, 2- it’s easy to get stepped or kicked while people are getting in or out of the car, 3- I can already see it getting wacked and loosened while cleaning the car. It was fairly easy to install, jacked the rear pumpkin and chocked front wheels. Drilled 6holes done! My only grip why not have predrilled holes for you and make it dumb proof? Guess that would prevent adjusting it however you want but still

      Decent fit

      Great quality but the fit is iffy at best. Instructions are very vague and are left to the owners decision on how the final fitment will sit. Lining up the part with the body leaves a misaligned inner fender portion. Very frustrating with someone who likes great fitment. Parts are very sturdy and should last a long time.

      Exactly what I was looking for

      Super easy install, and in my opinion the look way better than the Roush ones.

      Another awesome addition for a great price

      Good solid quality, for a good price. Matches up perfect with stock ABS parts. Adds a nice sporty touch to set the car aside from the rest. These paired with the chin spoiler winglets is a great combination. Install is very easy to do by yourself at home with a jack and jack stands as well. I highly recommend the product

      Quality product, looks great!

      Drilling into my new 2 month old GT? Sure why not! The MMD side rocker panel winglets are very sturdy and look oem. Installation is pretty straight forward but there are no holes or template to guide you. The hardest part is getting them even on both sides of the car. I recommend drilling one hole first, then putting the push pin into the winglet/rocker panel so it will hold it in place while you drill the other two holes. Also be very careful when drilling, you don't want to go through the upper part of the rocker panel. I installed mine about 1/2" out from the rocket panel and they look great. The only negative is that you have to remove the factory plastic 'flaps' which are supposed to improve mpg slightly and also keep the end of the rocker panel tight. When they are removed the rocker panel will wiggle a bit on that end (where the winglets are installed). Not a huge deal but something to be aware of if you decide to pick these up. I'm happy with this purchase and the winglets add a subtle yet sporty improvement to the overall appearance of my car.

      Winglets

      I purchased the front and rear winglets to match. They give a subtle but aggressive look, and were really easy to install!

      Rocker panels

      The winglets are a simple add on that will get lots of looks and comments. Not flimsy but high impact plastic. Will help your car stand out from most.
