      Subtle, Retro Styling. If you want to keep your new, modern Mustang looking the part with a hint of retro styling, look no further than AmericanMuscle's Matte Black Quarter Window Accent. Styled to have the look of a quarter window louver, these window accents can give you the same effect without the installation hassle. Keeping the sleek look of the newer gens, these window accents allow you to pay homage to the 60's and 70's style Stangs, while also giving your ride a bit of an aggressive boost. This accent piece is also great for creating a blacked out look on darker rides.

      Highest Quality Vinyl. Upgrading your ride with AM's Matte Black Quarter Window Accents means getting the highest quality out there. SEC10 uses high quality 4 mil wrapping cast vinyl with a built in protective clear coat. This vinyl is designed to last the wear and tear of outdoor weather for at least 8 years. This makes our vinyl extremely durable and superior to that of our competitors' calendared vinyl which can begin to degrade in a few years.

      Air Release Technology. Our Matte Black Quarter Window Accents feature air release technology. This technology features mini air channels that allow trapped air to be eliminated from underneath the vinyl. The air channels prevent the vinyl from bubbling and wrinkling for a smooth installation.

      Perfect Fit Guaranteed. All of the SEC10 vinyl designs have been test fit, refined and then tested again on our very own fleet of vehicles, ensuring a perfect fit every time.

      Application. SEC10' Matte Black Window Accents will fit any 2015 to 2021 Ford Mustang Fastback/Coupe including the V6, EcoBoost, GT and Shelby models.
