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 2015-2017 Fastback Mustangs including the V6, EcoBoost, GT and Shelby GT350 models.

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

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.

Besides not buying...can you recommend how to "theft proof" the louver? I'm worried how someone can easily remove the nuts from the bolts then purchase the mounting brackets from AM. Thanks!

RenG

  • The closest to "theft proof" The MMD ABS Rear Window Louvers can be would be to replace the included nuts with lock nuts, however we do not recommend this, as lock nuts will apply more stress on the studs when installing. At this time we are not aware of any other type of hardware that would make this more difficult to remove.

    Great part. Easy install

    This is a fantastic part. It looks awesome on my 2016 Mustang GT. It was an easy install even by myself. Just take your time it will come out looking fantastic. The only suggestion I have. Is that when you silicone your pads down. Tape everything off before hand, apply the silicone, run the bead with your finger, then peel the tape before the silicone has a chance to dry. It will come out looking fantastic

    Everything is great except...

    I love the look on my car. Defiantly gives it a more aggressive look to it, while not hindering visibility out the back of my car. But during the install there is a bit of an issue. The connection between the metal plate and the small bolts is very weak. While finishing up the install I had tightened the nuts on the louvers two of the bolts snapped off! I am aware not to over tighten them so nothing would strip but about a quarter turn past hand tightened had snapped the part. Poor Quality in my case...

    Fit and finish

    I like the look of the part but the fit left a lot to be desired. The bottom of the part lifted up in the middle and the top right corner was a little high compared to the left I expected it to be a lot better fit for the price. It looks good from a few feet away but up close it would be a hard sell. It would be different if I didn't follow the instructions but did everything they said and still didn't get a good fit. It is an expensive add on not to fit well.

    Looks great but cheap hardware

    I have a 2017 EcoBoost and the louver looks great on it however when you are install them you have to make sure that you do not go past fingertip tight because when I was on the installation two of the screws on the bracket just popped off. For the amount of money you would think the brackets would be better quality.

    Perfect fit, easy install

    Love this retro look. Very good abs plastic. my only problem with these was the very bottom part of the louver was a little warped and was hitting the trunk lid when I opened it. I modified it to eliminate the problem by heating it up and cutting the warped section out. Looks like it was made this way.

    Great Louvers, Cheap hardware

    The louvers fit and look fantastic, the rearward visibility is unaffected unless in rainy conditions as water just loves to cling to the back window. The louvers themselves feel very solid and I have not experienced any chatter even at 80mph. However, the good stuff ends there. The mounting hardware is junk, Abs plastic plates with little screws, if you tighten the screws barely any more than finger tight they just snap clean off the bracket. I broke one but AmericanMuscle's great support shipped me out an entire new assembly kit within the week so no big deal.

    Really Wanted to Like These

    I really like the look and style of these and wanted them on my car. I'm not sure if they're just pimping them out without quality control or what, but I had two bad sets in a row. First off, these are not just an ABS plastic like what you see on your splitter. There is a coating or paint of some type. It's a thin coat. When my first set arrived I was getting ready to install them, but I'm glad I looked over the piece before sticking on all the mounts. The thin coating was flaking and peeling in a few places. Underneath revealed a grayish color. Not sure if it was some type of primer or what. AM responded promptly and sent a new set before I could even get the first one picked up. Great customer service. Unfortunately, the second set was exhibiting the same poor quality. Not sure if the paint they're using was a bad batch or if they didn't bake it right to cure it. Either way, disappointed. I could have sanded it out and had it painted, but that's a lot of extra work for a piece that's pretty expensive to begin with. When these are in stock regularly and the excitement has died down I may try again hoping that they've slowed down the process to ensure it's a good product. I'd really prefer a high grade ABS unit without the coating, though. Not sure if it would make the unit more expensive or not, but it would be better for dressing up as well as longevity. I have a feeling that coating will fade badly after a couple years of weathering. Especially in the FL sun where I am.

    Wow

    Highly reccommend to watch youtube installation guide from other users before installing it yourself. Pretty straight forward but they can give you extra tips to make the installation much easier. Material does not feel cheap at all, not heavier but does give you a quality feel. Inside the car the rearview is clear only when it rains and the water seems to cling on to the louvers and could make it less clear but not much of a big deal for myself personally. Even thought the silicon are very adhesive once you placed the plackets on the rear window. Make sure you let the silicon sits thru more than 12 hours before putting on the louvers orelse it could get messy with the silicon sticky around. Best solution if you get your hands with silicon is: Alcohol. (Use a pair of gloves to avoid any accidents) The louvers change the look entirely and give an impressive aggressive look to your car. Check out the photos from other users and you can see the difference.

    MMD abs louver

    Hi ya'll, The louver itself looks great. Once I received it I thought it flimsy for the price. But anyhow it looks great, took about an hr to install and im generally happy with it. Now the rub, before purchasing it inhad seen a video of a guy who installed it on hos car. The louver buckled way at the bottom. His buckled allot, my solution was to pull on the louver from the side. My friend did the same on the other side. The louver looked great. On a hot day my louver also buckled but not like the video in had seen. That guy actually cut that center piece out. It's a shame as these aren't cheap. Overall happy with the look. Hope you guys have a better experience with the product.
