      Classic Muscle Car Styling. A SpeedForm ABS Rear Window Louver is a great way to complete the classic muscle car styling of your 2005-2014 Mustang. Rear window louvers are a very popular aftermarket accessory that harken back to the muscle car era of the 60's and 70's, and now you can have that same styling for your modern pony.

      Lift-off Design. This SpeedForm Rear Window Louver will give your modern Mustang classic muscle car styling. With a convenient lift-off design, you can still keep your back window clean. This Louver is not hinged, so there is no need to worry about people messing with them when parked in a public area.

      Durable ABS Construction. SpeedForm manufactures their Rear Window Louver from high quality acrylonitrile butadiene styrene (ABS). ABS is an extremely strong material known for its light-weight, superior durability and impact resistance - making it perfect to withstand the hazards of daily driven vehicles. This Louver is completed in a fine grained stippled texture for a factory look that helps to hide the appearance of rock and stone impacts.

      Installation Tip. After installing the mounting plates with the supplied 3M bonding tape, be sure to seal off the edges with silicone to prevent moisture from damaging the integrity of the 3M bonding agent.

      Application. This SpeedForm ABS Rear Window Louver is designed to fit all 2005-2014 Ford Mustang Coupes including the V6, GT, Bullitt, BOSS and Shelby GT500 models.

        really cheap design

        You can see razor knife cut marks from when the louvers where made. very thin and weak plastic, they constantly flop around while driving. I wish I would have never purchased them.

        DON'T go 120mph

        Hit 120mph and the louvers shook around and blew off hitting the cars behind me and causing an accident on the highway. They ripped off my back glass and tore apart in the process. I will say I was impressed with the amount of height they gained in the air after lifting off my vehicle before smashing into someone's windshield. (They were installed professionally).

        Wish I purchased the aluminum louver. With the heat of the sun this louver bows up. The wind gets under it and it raddles terribly. I put extra Velcro strips on and it didn't help.

        Rear Louver

        I must start by saying that if I had the opportunity again, I wouldn’t have purchased this. The quality is slightly below my standards, you can see the cuts. It rattles when I drive. After about 2-3 weeks the little metal plates that hold the louver on started coming off the window, I called AM about it and they sent replacement tape, but the tape was far too small to use on this. I do enjoy the handles that are present by making two of the openings slightly wider. It’s easy to see through if there’s a vehicle you can tell, you just can’t tell very much about the car. One of the reasons I got a rear louver was because I read that it keeps the backseat slightly cooler and out of the sun, but now I realize no one uses the backseat anyway. The other reason I got it was because other owners of louvers said that there is no need to get both louvers and tinting, so I thought I could get this instead, but you can still see fairly clearly through the louver into the car, and the sun flows in fairly freely. If you definitely need a rear louver, this one isn't too bad, but if you're on the fence about it then maybe look more into it. Easy install, definitely 100 recommend two people however.

        One word...Cheap

        Made from the same flimsy plastic as the 50-100$ ones on amazon. This is not American muscle quality and I was surprised by how flimsy it is. The mold had a ton of imperfections and the box arrived open.for some reason the nuts are hand tight only but the instructions show you using a ratchet. If I were American Muscle I would remove this from inventory. Do yourselves a favor and spend the extra 100$ on a better one.

        One of there worst Louvers.

        I put this Louver on my 2006 gt. It’s so flimsy and the cuts on it are terrible. One of the slats on the bottom is almost all the way closed and a few other ones look the same. The support bars in the middle are cut into and cuts are not clean at all. Not worth $200 would recommend another company or website.

        Speedform Rear Window Louvers

        Speedform Rear Window louvers look good. Easy to install but would recommend you have help so they are positioned correctly over rear window. I also installed the Speedform Quarter Window Panels. I did not paint and their black finish looks good against the dark blue metallic paint of my Mustang!

      Questions & Answers (3 answers)

      3 Top Rated Questions

      My Mustang is my daily driver, and I use it all year round. It is never under cover. My biggest fear is that the tape will become weathered then unstuck, and the louver will fly off into the cars behind me. 1. Has anyone had any problems with the tape losing its adhesiveness after being exposed to long term combinations of rain, snow, sun, and speeding down the highway? 2. What is the longest anyone has had this installed on their car?

      • As long as the brackets are installed properly, you should not have any issues with them coming unstuck. If you were concerned about them staying, clear silicone can be added to the brackets during installation.

      Do these come already painted to match your car?

      • These do not come pre-painted.

      Can you really see out the back of the car with this brand as opposed to the mmd one?

      • The visibility of these louvers compared to the MMD louvers would be the same. You can still see out of the back window with these louvers in place.
