    Sporty Styling. A pair of SpeedForm's Gloss Black Sport Quarter Window Louvers are a quick and easy way to add sporty styling to the exterior of your 2015-2019 Fastback Mustang. Featuring a louvered chevron design, these C-Pillar Window Louvers will enhance the bold styling of your S550 Pony's body lines.

    Quality Construction and Materials. SpeedForm's Sport Quarter Window Louvers are manufactured from vacuum-formed acrylonitrile butadiene styrene (ABS) plastic for its light weight and long lasting durability. These Quarter Window Louvers are then completed in a smooth gloss black finish for aggressive good looks.

    Peel and Stick Installation. No messy glue or drilling is required for installation. These SpeedForm Sport 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 gloss black SpeedForm Sport 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.

      Best looking louver

      These louvers look real aggressive on the quarter window. You can still see through the quarter window when driving too.

      Just terrible

      I had so much trouble receiving this item i gotten these louvers For my red 2015 s55o mustang and sent to my house three times already and each time I receive it after a long wait . The louvers come in with a damage broken louver it would be the right louver first shipment then the left louver the second time and I would have to send them back and get another shiped waiting once again then finally after the third time trying to recive this item I finally got the louvers in one piece . Honestly not worth the trouble of ordering these louvers ether the louvers are cheaply made or they need to change the way they pack the louvers

      Look great, fitment was a little off

      The product does not curve with the glass so the edge of it sticks out a little but other than that , they look great

      SpeedForm Sport Quarter Window Louver

      Product is not made well, the paint is cracking and peeling off the louvers. I have only had these for a month or so and they are about to have to come off my car.

      Finish Issue.

      Gloss black finish started peeling off within a month. Inexpensive but really not worth anything unless you plan to refinish them yourself or you're just into the peeling look.

      The louvers are easy to install. You may need to get a thicker 3m tape. And I had to trim a ridge down to get it to fit correctly. For the price I would buy them again

      Great louvers

      I installed the louvers on my Kona Blue 2019 Mustang California Special Edition. Easy install and they look great.

      You get whaat you pay for

      Product was a good fit dimensionally but was either too stiff or the 3M tape not strong enough to conform to the curve of the front edge of the quarter light. The worst part though, in the Florida Sunshine, 25 of the paint on one louver peeled right off. The price was excellent and the product looked really great until the paint peeled. Might be good in Northern climes or maybe I received one bad example.

      Very nice/look great

      Great product without spending big bucks. The angles match the 2018 taillights well.

      Badass

      Exactly what I wanted. Give my mustang a more meaner cool feel to it. It’s way to easy to install. I would recommend getting wider double sided tape, it works a lot better than the stuff they give you.
