Enhance your 2005-2014 Ford Mustang Coupe with SpeedForm's Pre-Painted Quarter Window Louvers. These louvers offer a classic muscle car aesthetic with their bold, four-slot open design, providing a muscular styling while maintaining visibility through the c-pillar windows. Constructed from durable and lightweight ABS plastic, these louvers are built to withstand daily driving conditions. They are painted in-house at AmericanMuscle using the same base coat clear coat urethane paint that Ford uses, ensuring a perfect match to your Mustang's factory exterior color for the 2005-2014 model years. Installation is straightforward, utilizing the supplied 3M automotive bonding tape. Simply clean the surface, peel the backing, and apply. No drilling or messy adhesives are required, making for a quick and easy upgrade that can typically be completed in about 30 minutes. These louvers are sold as a pair, including both the driver and passenger side components. For an even more cohesive look, it is recommended to pair these louvers with quarter window blackout decals.
