    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 2015-2018 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.

    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?

    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.

    Can the louver go through the car wash while on the car? Will it break or get scratch or fade?

    MarkC

    • The MMD ABS Rear Window Louvers (15-18 Fastback) can be taken through most car washes, however, depending on the pressure of the water and the power of the brushes, it is possible that the louvers be damaged during this process. We would highly recommend removing the louvers prior to any car wash to ensure that damage does not occur.

      Great look, some issues

      Most of the issues I saw people noticing seem to be fixed. The louvers have padding so I hear no tapping sound. My only issue is that the brackets are garbage. I took the louvers off twice, and the metal pegs broke and am currently having problems getting it warrantied. Super easy to install. Took me ten minutes (not accounting for curing time)

      A badass upgrade!

      Great product, definitely makes your car stand out. Took me about 30 minutes to install and the process was very easy. The only issue I had was an awful vibration on the highway (75mph higher). I fixed this vibration with double sided 3M tape on the top middle section of the louver.

      Fitment was excellent. Only issue was a little buzz during high wind speed that I had to insert a little seal type cushing between top of louver and glass.

      Great look but bad quality

      For $400 you would think you are getting a quality product that is made with the consumer in mind, this is false. The brakets that this product comes with are extremely cheap, the screws snap off the brackets with light touches so you have to be extremely careful when installing. For example I was Simply attach the louver to me car after waiting the full 24 hour cure period and upon placing the louver on the bracket on snapped. Another one snapped when adjusting the louver to match up with all the brakets. For $400 this product should be made properly. The look is great though and the install was easy. The other good thing is that American muscle is currently in the process of sending me replacement brakets. If it wasn’t for AM’s help I would Be extremely disappointed.

      Good looking but horrible quality

      For paying over $400 on this you would think it would be made of a good quality. Looks are there but the screws that go on the window broke on the first day of installing this and than for couple months I have this all the top screws are broke I had to use doubleside tape so it won’t be flopping up and down horrible quality very disappointed

      Loud vibration sound

      When traveling at speeds greater than 70 mph, there is a very loud vibration that will be heard until you slow down. It's annoying and had I known upfront I would have opt'd for the additional expense and got the metal louvers. outside of that - very easy to install and looks great..
