Upgrade the side profile of your 2015–2023 Ford Mustang with these GT500-style side skirt extensions, designed to add a wider and more aggressive appearance inspired by modern track-focused Mustang aero packages.
Constructed from durable HDPE material, these side skirt extensions feature a matte textured finish similar to OEM performance aero components. The design integrates with the factory Mustang side skirts while extending outward to create a more pronounced aerodynamic look.
These extensions offer approximately 1 inch of adjustability, allowing you to fine-tune how far the skirts extend outward depending on the level of aggression you want for your build. The design also keeps the factory pinch weld lifting points accessible, so the vehicle can still be safely lifted using jacks or vehicle lifts.
These side skirt extensions are designed to pair perfectly with GT500-style splitter winglet extensions, creating a cohesive front-to-rear aerodynamic appearance.
Proudly manufactured in the United States, each set is built to order using durable materials designed for long-term use.
