      Classic Styling. A pair of Pre-painted SpeedForm Quarter Window Louvers are an excellent way to add the classic styling of the muscle car era to your 2015-2019 Fastback Mustang. With a four-slot open louver design, these SpeedForm Louvers will give your S550 Mustang bold, muscular styling while still allowing you to see clearly out of your c-pillar windows.

      Painted Here to Match 2015-2019 Factory Mustang Colors. These SpeedForm Quarter Window Louvers are painted right here, at AmericanMuscle HQ. AmericanMuscle uses the same base coat clear coat urethane paint Ford used on the exterior of your 2015-2019 Mustang to match your stock color perfectly.

      Quality Construction and Materials. SpeedForm's Quarter Window Louvers are manufactured from vacuum-formed acrylonitrile butadiene styrene (ABS) plastic. 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.

      Peel and Stick Installation. No messy glue or drilling is required for installation. These SpeedForm Quarter Window Louvers are designed to attach to the factory C-Pillar glass with the supplied 3M doubled sided automotive bonding tape for a quick and easy installation. Just clean the surface, peel the backing and stick in place - it's that easy.

      Recommended Styling Upgrade. When installing exterior quarter window louvers or scoops on your Mustang, it is recommended to add a set of quarter window blackout decals to hide the ugly back side that wasn't meant to be seen by human eyes. See part number 386505.

      Application. These Pre-painted SpeedForm Quarter Window Louvers are designed to fit all 2015-2019 Fastback Mustangs, including the V6, EcoBoost, GT, and Shelby GT350 models. Sold as a set of two, one driver side and one passenger side.

      Find Your Paint Code

      • Choose the year of your Mustang from the options above. The color choices displayed will be the only exterior paint colors available for your year Mustang. The first two letters for each color option are the paint code for your exterior color.
      • If you don't know what your paint code is off hand, look inside the driver side door jam at your VIN plate for verification.

              Looks good, Easy to install.

              Love the product, but really expensive for Canadian customers.

              These pre-painted louvers arrived earlier than expected and were a perfect match for my GT.

              Paint has flaws on the edges of the rubs. One of the louvers has sand embedded in the paint

              two scratches

              There were two scratches on one panel. I was able to get one out with Maguire scratch product. I used paint touch up on the other but if you look close can still see scratch. The color matched perfectly and panels still look decent.

              You Get What You Pay For

              Very cheaply made and the pain job was the worst that I have ever seen on an American Muscle product. The paint was chipped, the vents between the louvers had paint missing and there were bubbles and debris in the paint. Because I installed them before noticing the terrible paint job, I had to really work hard to convince A.M. replace them. Thankfully, I had a wonderful rep talk a supervisor into the return. Please make sure you check the paint job before you place these on your Mustang, otherwise they will not replace them...better yet, steer clear of these altogether!
