    Review & Install Video

    Hey guys, Stephanie with AmericanMuscle.com, here with my review of MMDs ABS rear window louvers fitting the 2015-2016 Mustang. So the 2015 clearly has a more modern look, and there are some S550 owners out there that want to mix in some of that old school Mustang feel. The MMD rear window louvers are definitely a kick-back look for those '15 owners. These louvers are a one-piece design made from ABS material that can stay as is or could even be paint-matched if you want. Looking at them here, I can tell you that they're lightweight but feel durable, and look like they should hold up through all different types of weather. The lightness and weight is also good because it's not like you're strapping more weight to the back of your window. The one thing I was worried about was the visibility out back. So I hopped in the car to check it out and was actually surprised by the amount of visibility I had. MMD designed the louvers with that third brake light in mind, and these kind of angle down at the same angle as your rear windows, so you can still see nearly everything behind you. Talking price, these are coming in just south of 400 bucks, and they're going to be less expensive than the aluminum louver option. Both options will help in giving more of a retro look, and the aluminum option will look a little different compared to these. But it really just comes down to preference. The install is not difficult, and I'm giving it one wrench on our install scale. The initial install should only take an hour. But to get your brackets positioned on the window, you will be running a bead of silicone sealant around the brackets, which will skin over in about a half-hour but then take 24 hours to cure. Make sure you wait out the 24 hours so that the brackets are fully secured on the window. After it's cured, you'll finish the install by attaching the louvers to the brackets. Other than the waiting period, this couldn't be easier. And since they install so easily, they also uninstall very easily in case you ever want to pop them off and clean your rear window. So again, if you're an S550 owner who wants to combine old and new, these are certainly something to consider. They're definitely retro, they seem durable, and they're easy to install. These are the MMD rear window louvers for all fastback '15 and up Mustangs, which are available here, at AmericanMuscle.com.

    Muscle Car Styling. Add unique muscle car inspired styling to your S550 Fastback Mustang with this high quality Modern Muscle Design ABS Rear Window Louver. Rear Window Louvers were very popular in the 60's & 70's and now you can have that same cool, retro styling for your very own late model pony. MMD designed their Rear Window Louver with the third brake light in mind, and continues the angled design down the entire louver for a unique look that still lets you see clearly out the rear window.

    Convenient Lift-off Design. This MMD Rear Window Louver will not only give your modern Pony a classic muscle car appearance, but with its convenient lift off design it can easily be removed for routine cleaning of your back window. They are not hinged, so there is no need to worry about people messing with them.

    High Quality Construction. Manufactured from high quality acrylonitrile butadiene styrene (ABS), this MMD Rear Louver Spoiler was designed using the original OEM CAD data from Ford to ensure a perfect fit. ABS is an extremely strong material known for its light-weight, superior durability and impact resistance. This Modern Muscle Design Rear Window Louver features a factory style grained texture for an OEM appearance.

    Paintable Black Finish. Completed in a textured black finish out of the box, these MMD Rear Window Louvers can be installed as is for a great aggressive look. However, if you're not a fan of the black finish, the Louvers can be painted to match your Mustang's exterior color scheme, the choice is up to you.

    Simple, Straight Forward Installation. Modern Muscle Design engineered their Rear Window Louver to install simply with no drilling required. This MMD Rear Louver uses a series of mounting brackets that secure to the exterior rear window with 3M automotive grade bonding tape. Installation can be completed in about one hour with just basic hand tools, but you should wait at least 24 hours for the brackets to fully cure before driving.

    Application. This Modern Muscle Design ABS Rear Window Louver is designed to fit all 2015-2019 Fastback Mustangs including the V6, EcoBoost, GT and Shelby GT350 models.

    I was wondering how hard it would be to wash the rear windshield when these are attached? I'm concerned about dust, dirt, bugs etc getting through the louvers and onto the rear windshield.

    • Hello! These Louvers feature a lift up design where you are able to pull up the louvers to clean the rear windshield, and then put it back down.

    I live here in Vegas and the Temps get extremely hot, especially items that are black in color. Will this thing sag and survive Temps in the 110 to 115 range? I was thinking about the aluminum one, but it has a bar in the dead middle and I'd rather not have it there. Thank you, Mac.

    • Hello! Prolonged exposure to those temperatures may cause the adhesive on the MMD ABS Rear Window Louvers to weaken.

    How should this and its adhesive hold up in MInnesota winters? It gets to -30 / -40

    • If installed correctly, there should be no issue with these louvers in those temperatures.

    My 2016 Ecoboost came with the factory wing or spoiler blade, meaning I do not have a fastback, does this mean the product will not work?

      Looks good

      Don't use anything but hand tightening. I sheered off the bolt from the mounting bracket and had to JD weld one. JD weld holds about as good as the bolts are mounted (which isn't great but not much is needed)

      Disappointed

      I really like the look..... I bought the Louvers for my 2017 Ford Mustang in NOV of 2017, I have had it on for almost a year. I had to replace the hardware 3 times, the Louver is now buckling near the trunk, so it hits my trunk door when its being open. The product material is not worth the money I have paid

      A must for the rear window

      I really like the window louver and you can install it from home but you will need at least 2 people if you want to place the window louver properly. The only thing is its quite expensive but in the end its worth it

      Looks great once it stays on!

      After following the instructions for the prep and installation, left the brackets on w/o the louver for a full 72 hour cure. After three days, several of the brackets started coming off. I ended up removing the brackets and the tape and applying 3m vhb and repeated the installation once again. Since then no problems.

      Awesome way to differentiate from the crowd!

      The product looks amazing and installation was super easy! When it first came, the box included no installation tools. I was obviously upset especially considering I paid extra for 2 day shipping. Without argument they immediately refunded me my extra shipping as well as gave me an extra $15 to spend on future purchases. I went on to purchase my roush air intake a few months later.
