    Vintage Styling. A great way to add the vintage styling of the muscle car era to your 2015-2019 Fastback Mustang is with a set of SpeedForm Vintage Quarter Window Louvers in matte black. With a five-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.

    Quality Construction and Materials. SpeedForm's Vintage 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 matte black finish for aggressive good looks.

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

        because the window has a slight curve the louver does not sit flush and the lower inside corners don't stay glued down . what do u recommend to make sure that then do now continue to pull away from the glass

        Can we get a picture of the view from the driver's seat. I want to see how much these would block my vision while driving.

        Can these be painted? I'd like to match them to body color of my Mustang.

        • The SpeedForm Vintage Quarter Window Louver can absolutely be painted to color match your vehicle. Some minor sanding and preparation will need to be preformed but can absolutely meet the proper criteria to layer primer and paint.

            Eh.

            They look pretty good and for the price theyre definitely worth it. However, out of the box, the corners were slightly warped and took a lot of coercing to fit. They are still not flush but oh well.

            Feel like their price

            Save your money and get something better. I wiped them with an alcohol prep pad to prep these. Huge mistake they’re stained with alcohol residue nothing I’ve tried has fixed them. I’m going to attempt to paint them. FYI when AM says use soap and water use that lol... Totally on me but I wish I had just bought something painted.

            Louvers

            The corners are hard to get them to stay. It looks cheap, especially with the metal back window louver. Not a great pick .

            I took them off

            They are okay, but don't really go with the look of the car. They are kind of cheap appearance wise, so takes away from the better mods. But like AM said in the review, these don't cost an arm and a leg so if you do not like them just remove them.

            Nice Retro Look

            The fit was perfect and the install was simple. This is a nice inexpensive addition. Although there is some reduction in the viewing area from the drivers seat, my ability to see in the blind spots was still good.

            They are super easy to install, the 5m tape definitely keeps a good hold on them! Not to mention giving my car that modern/classic look!

            Good for the Price

            For the price, I got exactly what I was expecting. They feel as this as a red solo cup, but the finish scratches easier. They're molded to be pretty straight, but there's a slight curve in the glass. This means the bottom of the louver pulls away from the glass, even after upgrading to a higher quality tape and using adhesion promoter.

            Great quality

            I love them! The only problem is the double sided tape provided is not as strong as it needs to be. I went to autozone and picked up some double sided 3m tape and put it on with that and it’s perfect!
