    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.

        Does it cause wind noise?

        Will an automatic car wash crush or damage these louvers when the cylinder passes over the rear windshield?

        • We do not recommend going through the car wash with the louvers installed as they could potentially get damaged. It is highly advised to remove them before going through an automatic car wash.

            2nd Time's the Charm!

            First time I installed the louver, I heard the very obnoxious rattling noise anytime I went over 60mph. It didn't fully make contact on the bottom towards my trunk and allowed for the wind to get underneath. Removal process is a PAIN because those suckers really do stick to your windshield. (Had to buy adhesion removal spray, etc. it was a task) Second time around, used duct tape to outline the placement more precisely and problem solved!

            Looks great on our 2015 ecoboost!

            Instilation was was really easy and it took about 30-45 minutes. We've had this installed for about 2 years now and have had zero issues with the adhesive coming loose or the ABS plastic cracking.

            Looks Awesome

            PLEASE take your time and follow instructions exactly as written. Looks great! Suggestion, buy a small ratchet wrench with rubber teeth. Keep in the glovebox so u. an easily remove the hex nuts when u want to clean rear window. The rubber teeth will keep the hex nuts black coating from peeling or chipping off

            Gotta love Pony Parts!

            This is one bad @$$ louver for my Pony car! It fits perfectly (side to side) and a little gap at the bottom (which you NEED!) so it won't hit the trunk as you pop it as others have said. The ONLY reason I'm giving this a 4 star is because the thin piece at the center-bottom will not lay flat against the window when the sun is beating down on it. It was perfectly flat last night when the temps were cool, but popped up about 2 inches from the glass at high noon today (can we say thermal expansion??). I'd thought about putting a spare 3M pad there to hold it down, BUT...I can't remove the louver to clean the glass then, now can I? (sigh) It is what it is! No rattling on the glass because there's black flexible tubes attached to the underside of the louvers (in the middle) to stop that. Great idea, MMD! Oh, I also shot it with a light coat of clearcoat to keep a good shine going! It IS pricey for what it is, but for the killer look on your S550, this is the one to get!

            The louvers look great on my 2015 Mustang GT. It is very secure against the rear glass and I have no vibration in the louvers. Awesome retro look! Make sure you follow the directions and let the attachments dry for 24 hours before installing the louvers.

            Looks great, but the price is a little steep.

            I wanted louvers for the longest time and finally decided to pull the trigger on these and I am very glad I did. They look awesome on the car and have an awesome design that isn't bland or throws off the body lines on the S550. The material is a nice ABS plastic too, but it isn't anything super special, and makes me wonder why it has a $400 price tag. Nonetheless, if you have the money, I'd definitely get these.
