    Vintage Styling. A great way to add the vintage styling of the muscle car era to your 2015-2020 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 2015-2020 Fastback Mustangs, including the V6, EcoBoost, GT, GT350 and GT500 models. Sold as a set of two, one driver side and one passenger side.

        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.

            Window Louvers

            Very easy to install. Tape used to adhere louvre to window is not very strong and plastic can come off. Recommend using a silicone gel adhesive.

            No tape included :|

            the build quality is fantastic, they seem to fit well (from holding them up to the window) but no 3m tape was included, so I'm not sure what the final look will be. would've been cool to have some as I see it in the product photos

            Ok

            These are one piece plastic and definitely look plastic. The louvers are not contoured to the window shape so despite the double sided tape, they do not adhere at the bottom corners well.

            Horrid fit; too rigid

            Like many others... the tape was garbage and the fit was slightly off. I would have had to sand/shave off at least an 1/8th of an inch off the top/bottom to get it to fit past the window molding. As to others complaints about the bottom front corner pulling away from the window - that is neither a tape nor window arc issue - it's because the louvers are too rigid to flex slightly to follow the shape of the window. I got another set of louvers (for $40 as well) that have more give to them (same matte ABS finish) and they followed the bend in the windows and stick just fine.

            Looks good and worth the price

            Make sure you get the placement right the first time, as you would expect after a few tries the tape gets less sticky. They don’t look cheap and the amount of sunlight in the backseats and in the corner of my eye is reduced largely.

            Pretty good product

            As written by others they are flat and not curved like the window you will be sticking them to. I had to buy some 3m high strength bonding tape to get them to stick. The forward lower edge will occasionally pop up. I did end up painting them a satin black and they turned out pretty good. Eighteenonebay.

            Perfect look and fit.

            The product fits accurately on my 2019 Mustang. The matte black color looks great on any Mustang--regardless of the color. I am a satisfied first time customer and will definitely shop via americanmuscle.com again. Also, the delivery was sooner than expected.

            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.
