    Hey, I'm Justin with and I'm taking a closer look at MMD's classic quarter window louvers, fitting all 2010 to 14 Mustangs, available in your choice of either unpainted or pre-painted. If you're looking for a retro or modern styling part that's going to separate your ride from the rest, look no further than MMD. They've quickly become the industry leader in producing cool and stylish appearance parts for mustangs of all ages. Now, if you guys want to see more killer parts from MMD including some of their wheel offerings for the S197, go ahead and click on that link below to subscribe to our YouTube channel if you haven't done so already. So the classic quarter window louvers from MMD are definitely one of the more popular appearance parts here on the site and are, of course, inspired from the iconic 60s Fastback Mustangs. Now, thanks to the retro lines of these modern S197s, the louvers look right at home here on our 2014 GT. Taking a closer look at the louvers themselves, you'll notice that MMD went with a lightweight yet extremely durable ABS plastic for the construction, all of which have been injection molded making for a perfect fit and finish. As I mentioned at the beginning of this video, you do have the option of grabbing these louvers unpainted, or for a few bucks more you can spring for the fully painted version shown here. Now these louvers are sprayed in our state of the art paint booth at American Muscle headquarters, making for a perfect color match right out of the box. Now guys, go ahead and click on that link below if you want to head back to the product page at for a full breakdown of all the colors available for this louver. Included in the package, you'll find everything needed to install the louvers, including the 3M automotive dual-lock adhesive tape, which basically allows you to remove the louvers after they're already been installed to clean the rear window. Now for the install itself, you'll first want to clean the backside of the louver and the quarter window using the alcohol prep pads. Grab your adhesion promoter and then wipe down those same areas. Install tthe 3M automotive tape to the backside of the louver, remove the protective backing, and adhere the louvers carefully to your ride. Getting everything installed is only going to take you about 30 minutes from start to finish but if you should have any problems with the install or if you just have any questions, you can always get in touch with one of our Mustang experts. If you're looking to add iconic 60s Fastback styling to your 2010-2014 Mustang, then be sure to check out MMD's classic quarter window louvers available right here at

Available for 2010-2014 Mustangs, see drop down option above.

    Application. These Pre-Painted SpeedForm Classic Mustang Quarter Window Louvers are designed to be a perfect fit on any 2010 to 2014 Mustang Coupe, including the V6, GT, BOSS or Shelby GT500 models. Sold as a set of two, one driver side and one passenger side.

    Can you see out of the window with type of louver on the window? I want to purchase them because they are cool looking and make my Mustang look even better, but if it is going to hinder my vision I will pass and purchase other stuff for my Pony.


    Helpful (2)
    • Yes you can still see out of the window. Inside the car they are angled to give you some visibility. I was concerned too, that is why I didn't get the blackouts. You will also start using your side mirrors more, which is a good thing.

    is water able to drain out from behind the louvers?


    Helpful (0)
    • You should not have any issues of water getting stuck in the louvers and causing damage.


    I assume these aren't meant to be removed, so is there any way to clean the quarter window glass with these on? I'm worried about stuff getting inside the louvers and building up over time. Also, if I ever needed to remove these, could I do so without damage/leaving marks?


    Helpful (0)
    • Actually, they are made to come off so you can clean the quarter window under them. At least, mine were. The install strips were a type of Velcro and the guy at the dealership just forced them off, cleaned the window, and put them back on. I was afraid I would screw something off so I paid the body shop 20.00 to pull them off, clean the windows, and put them back on. Usually about once every month or so and I had the car for 19 months when I traded it in on a 2016 and they still were holding fine. I had the body shop at the dealership install them so they were familiar with how they worked. You might check with your dealer and see if someone there know how yours work. Hope this helps


    The video mentioned taking these off periodically to clean the rear quarter windows. Can these be put through a car wash?


    Helpful (0)
    • I just traded my 2014 GT for a 2016 GT but I have mine on the 2014 stang for a year and half and it went thru many car washed and never came off. They fasten on with a Velcro type of thing and you can pull them off and clean the rear quarter window and put them back on. I always had the dealer to do it when I got an oil change but I watched them do it and it didn't look very difficult. A little pull pressure to get them off and make sure they were straight going back on and all was good.


    I am confused about the first question asking if they were gray or black? I though these were prepainted, if you requested it.


    Helpful (0)
    • They are pre-painted as long as that is the ones you buy. You can purchase them either way and the description will say pre-painted if that is the one you buy.

      Great color match, don't underestimate the glue

      The color is spot on! The install is extremely easy the instructions are as clear as they can get, don't forget to wipe down the area well and use the glue sponge that is provided!! I didn't use them and after about a month one of the velcro strips came loose but I quickly applied it and no more problems.

      Excellent Dress Up Accessory

      Pros: Material quality is excellent; Paint and finish are exact match with my '10 GT, Fit and installation was a snap. New velcro-type tape is very strong and easy to install. I have had no problems with gaps or loose areas to date. As many reviewers have stated, make sure you do your homework and prep the windows beforehand. Tape would be difficult to remove. Follow instruction sheet as noted and you should be ok. Louvers add nice appearance to car. Slats in louvers allow for limited vision so you will need to depend more on side mirrors when in reverse, parking, etc. Cons: Alohol prep creates dull film over window; nothing major since louver covers that area but it is unsightly. Price is the standard for this type of product, but it is still a bit expensive overall.

      MMD Classic Quarter Window Louvers

      Thumbs Up! Getting them lined up perfectly was a little tricky but I managed to get it done. Used a trick where I peeled back the 3M tape at each place, just enough to pull it free once I had the louver lined up where I wanted it. I started by ling up the smallest corner at the rear, then lined up the bottom, and the rest fell right into place. Then carefully peeled the backing off while holding the louver in place and it worked like a dream. Color match was exact and they really make the car look mean. I still have decent visibility to my blind spots during the day, but have to rely on my mirrors at night. If you screw up lining them up during installation, don't fret. You can saw through the foam adhesive with braided fishing line, so you won't hurt anything. Clean off the adhesive and you can get another roll of the adhesive molding tape at any auto parts store. Once you get em on, you'll love the result!

      My 1st mod.

      I received these for Christmas, and installed them yesterday. I went to a local auto store for better 3M tape, just to be safe. These louvers really give the car a more "muscle" like feel. Visibility is impacted by a lot, but you can still see through the slots in the louvers. Also, when looking in the mirrors, you'll notice them, but they wont affect visibility when looking at your mirrors. Very good product.

      Mounting tape issues...

      I LOVE the way these look. I had them installed on my 2012 5.0 and just added them to my 2013 GT500. There is a problem with the fit. It gets blamed on the tape but if the louver laid flat this would keep it from pulling away so hard eventually causing the tape to fail at the rear corner. I'm having the dealership remove and reinstall mine hoping to provide permanent solution. FYI its not that bad and a lot of people could just live with the 1/8" -1/4" gap created when the tape gives...I can't.

      Forget the install kit

      Received my order promptly and did the install the following Saturday morning. I've installed louvers before and knew that the whole thing can go bad quickly. I followed the direction precisely and had them installed in less than an hour. After about an hour I went to check them to make sure all was well. That's when I noticed the rear edge on the left and the front edge on the right had turned loose from the louvers so I just removed them altogether and cut my own strips from a roll of 3M moulding tape and washed the windows down with rubbing alcohol and reinstalled. Stuck immediately and still stuck. They look great on my GT/CS. Get some 3M moulding tape and throw that install kit away. It's junk!

      Lots of style for the money

      Another top quality AM pre-painted part, perfect color match, nice smooth paint finish with not a speck of dust in it. Easy installation, I do not recommend the black vinyl decal to cover the window, because you still have some vision out of these and the louver doesn't look bad from the inside looking out. Buy 'em and you won't be disappointed

      Pre-Painted Window Louvers Installation

      I love them!!! I purchased these shortly after American Muscle made them available. I particularly liked the idea that they attach to the glass window rather then to the body of the car. You really don't have any measurements to take to center them, as they are manufactured to fit just inside the body frame of the window. Trial fit them before applying the tape to get comfortable with the installation, then just follow the instructions. Clean the glass and louvers with the alcohol rubs, apply the adhesion promoter to both parts, add the 3M tape and then install. You'll like the result.

      Love the way it looks!

      My quarter window louvers arrived within 3 business days and I couldn't wait to get them installed! The installation was fast and easy. I had one problem with one of the adhesives not sticking to the louver, which made the louver stick out from the window. I painted that little section with some contact cement, held it down against the glass and it is sticking perfectly so far after about 2 weeks in cold, rainy weather. It gets really hot in the Houston area in the summer months, so we'll see if it continues to hold. If not, I'll just reapply. Overall I'm very happy with how it turned out.

      A great piece with a minor flaw

      These are great looking louvers at a great price. The paint match (Race Red - PQ) was spot on, and the clear coat finish made them blend right in with the car. The one flaw i would have to point out is that the louvers had bits of dust particles and small bubbles throughout. The unpainted backside of the louvers had lots of dust and sticky tape still affixed(im guessing from the painting procedure) . So i had to wash them out and peel the tape off before putting them on. I would have returned them for another set but I had a car show to go to on the weekend so i went ahead and put them on. If these could just get painted in a dust free area, they would be flawless! I appreciated how they include 3M tape that allows you to detach it from the car to allow for window cleaning. Be careful when you go to line the louvers up though, once the tape sticks to your window, it is not coming off!
