The S650's flanks run long and flat between the arches. From the side, that is most of what people see, and the factory rocker does nothing with it.
Side skirt extensions in premium 2x2 twill carbon fiber, a Feral Auto design shaped to the Mustang's own rocker line. Sold as a matched pair, left and right, finished together so the weave and gloss match side to side.
Runs with the Sport or Track Front Spoiler — all six exterior pieces come together in the GT Exterior Bundle Kit (Sport) or the GT Exterior Bundle Kit (Track). Want the same shape for less? The FRP Side Skirt Extensions are the same design, primed for paint. This is one of the pieces that carries across the S650 range — see the full Ford Mustang S650 collection.
Fits the 2024-2027 Ford Mustang GT, Dark Horse and EcoBoost (S650).
Why Carbon Fiber
Carbon fiber earns its place over factory plastic on three counts. It holds a crisp edge where plastic softens and rounds off. It resists the flex and sag that makes a long lower part look tired after a season. And the weave is the finish itself rather than a coating applied over it, so a scuff doesn't expose a different color underneath.
A rocker extension is the longest unsupported span on the car, which makes it the first place a composite shows its limits. Sag in the middle of a side skirt is visible from across a parking lot, and stiffness is what prevents it.
