    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.

    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.

      rear window louvers

      they look great. fit great...... special note, when installing the 3m tape n then the brackets that mount on the 3m tape n on the window. take your time running n spreading the sealent around the brackets. if u use a little more thn normal kits ok. just gonna make it that much more sturdier. besides. when it dry's on the put the louvers on. its not gonna show thru the louvers... one mental note. the rear window louvers r supper flimsy and b careful when touching them. they could snap n break if u grab to hard. I suggest having a second person to help out

      If you like that 'tuner' look...

      I really like this! It does look great, it fits the window really well (which was the deciding factor) and it seems to be well made! Super easy to install ... it is best to have two people to lay it on, and when you go to put the adhesive preparer on, use one package for the window and the other for the stickers. Looks wise, its pretty good ... it definitely fits well and keeps the sun out, which is why I bought this one, as I wanted it to keep the sun off my dogs, who ride in the back seat. And if you like that tuner/Lamborghini look for your Mustang, this will be perfect for you, but for me, if the aluminum one had fit the window a tad better, Id rather have gone for that one... the straight slats just looked better, but it appeared to allow a little more light in. Function over form, in this case, for me.

      Totally awesome mod!

      These louvers are very good quality and look absolutely amazing on the car! Install (aside from the cure time) is less than an hour total and pretty easy as long as you have a second set of hands to set them in place. I had mine painted to match the car and the textured finish does require some extra prep, but they turned out beautiful! Totally recommend this item for anyone who wants to stand out.

      Great for looks

      After owning this product for more than half a year I can say that it looks awesome but the cons are if you have a windy day it may rattle very violently when you're close to around at the very least 80 Mph. Also, recently I've noticed that on a windy day if I let go of the gas passing 80 it acts like an air brake which causes the shaking but as long as you know that then it shouldn't be a problem where you could put a foam piece on the rear window to help out with that.

      Looks great!

      I wanted these louvers to help my Mustang during the hot Texas summer, but I wasn’t totally convinced that the look was that great. I will say though, now that I have them on they really do look nice, and I’ve already received several compliments on how great they look. Totally worth the price.

      MMD ABS Rear Window Louvers (15-18 Fastback)

      Put on my Shelby Cobra.... it works to block the sun off the back window. The color works "fairly" well with existing paint job. Things I would change about the product: modify the securing brackets to shape the base of the louver. You can see the glue and securing brackets through the louver. Be careful washing... spray wash and air dry as the product will grab towel/cloth fibers. Fit is snug, just make sure that you pull the top up a bit. If you install perfectly in line with window when you open the trunk lid, it will make contact with the louvers.

      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)
