    Sporty Styling. Add a sporty appearance to your 2015-2019 Fastback Mustang with a set of SpeedForm Sport Quarter Window Louvers. 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 matte 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 matte 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.

        1 Top Rated Question

        I've always been a little concerned that most of the louvers completely block any view. These appear to be shaped such that the driver may be able to see through them ie: they don't create a big blind spot? Is that the case?

        • The angle that the slots are positionedallows for a clear view through them. They do not cause much obstruction.

            Great for the money

            Fit is ok. Great value for the money. Used a thicker emblem tape than what was provided and had no problems. If they blow off I'll just get another set.

            Was real easy to install. Love how it looks on my ecobeast. Going to add full back louvers in the near future

            Great for the price

            I like the way the louver fit and look. I was super sketched out by the tape at first, but make sure you use all the tape that you get. I've had them on for about a week now and that includes a 6 hour drive and they still look perfect!

            Simple Accent

            These add a nice accent to your car without being too over-the-top. Easy to install - make sure your windows are clean and finish up with a wipe-down with isopropyl alcohol to ensure the tape will stick well. As others have noted, the louvers don't follow the curve of the vertical edge closest to the door, so the tape in the top and bottom corners won't stick. Get thicker double sided tape at an auto parts store for these corners.

            Looks good but...

            The look great on the car. You can't beat the price. However... The top and bottom corners that are closest to the door do not want to stick. I will probably have replace the 3m tape that came with it with some that is wider and maybe a little thicker. The louver is to stiff to want to bend to the curve of the window. I do not regret the purchase. I will just eventually need to remount them.

            The item looks fine but it doesn't stay on with the 3M adhesive. I had to redo it twice.

            Fits perfectly no issues at all. Matte black blends with factory trim like it came that way from ford.

            Great Looking Product

            This is a great small mod for your mustang. Easy installation and strong hold. The only downside is the plastic is a little flimsy and the packaging was poor. All in all the product looks good and pairs nicely with MMD Louvers.

            Look great, but don't quite fit

            Great looking quarter window louvers, but the manufacturer didn't take into account the curvature of the window when they made them. This makes it difficult to get the front corners to stay flush with the window.

            Decent

            As others mentioned, they arrive in terrible packaging which UPS almost flattened. Louvers looked okay though and one side fit perfectly but the other is where I noticed a slight bend in the corner that now won’t sit flush against the window. I’d rather pay a bit more to avoid this but not ~$200 so it is what it is. They look good but I’m expecting to have to reinstall with better tape or just remove them pretty soon. Oh well.
