    Description

    Muscle Car Styling. Add unique muscle car inspired styling to your S550 Fastback Mustang with this high quality Modern Muscle Design ABS Rear Window Louver. Rear Window Louvers were very popular in the 60's & 70's and now you can have that same cool, retro styling for your very own late model pony. MMD designed their Rear Window Louver with the third brake light in mind, and continues the angled design down the entire louver for a unique look that still lets you see clearly out the rear window.

    Convenient Lift-off Design. This MMD Rear Window Louver will not only give your modern Pony a classic muscle car appearance, but with its convenient lift off design it can easily be removed for routine cleaning of your back window. They are not hinged, so there is no need to worry about people messing with them.

    High Quality Construction. Manufactured from high quality acrylonitrile butadiene styrene (ABS), this MMD Rear Louver Spoiler was designed using the original OEM CAD data from Ford to ensure a perfect fit. ABS is an extremely strong material known for its light-weight, superior durability and impact resistance. This Modern Muscle Design Rear Window Louver features a factory style grained texture for an OEM appearance.

    Paintable Black Finish. Completed in a textured black finish out of the box, these MMD Rear Window Louvers can be installed as is for a great aggressive look. However, if you're not a fan of the black finish, the Louvers can be painted to match your Mustang's exterior color scheme, the choice is up to you.

    Simple, Straight Forward Installation. Modern Muscle Design engineered their Rear Window Louver to install simply with no drilling required. This MMD Rear Louver uses a series of mounting brackets that secure to the exterior rear window with 3M automotive grade bonding tape. Installation can be completed in about one hour with just basic hand tools, but you should wait at least 24 hours for the brackets to fully cure before driving.

    Application. This Modern Muscle Design ABS Rear Window Louver is designed to fit all 2015-2026 Fastback Mustangs including the V6, EcoBoost, GT, GT350 and GT500 models.
