2024-2026 Ford Mustang S650 GT350R-Style Side Skirt Extensions
or as low as $10.83/mo with Affirm
GT350R-inspired side skirt extensions that drop the visual ride height of the S650 and pull air tight to the rocker — picked in your finish, bolted on in an afternoon.
The S650 looks fast standing still — until you see it next to a car that's been finished properly. These rocker extensions hang below the factory side skirt and stretch the body line front-to-rear, so the whole car reads lower and longer the second they're on.
The shape is lifted straight from the GT350R Performance Package: a clean leading kick, a long flat blade down the rocker, and an angled exit ahead of the rear wheel. It's aggressive without looking bolted-on, and it ties the front splitter and rear diffuser together into one cohesive stance.
Pick your finish to match the build. Matte Black and Glossy Black ABS for a factory-grade painted look, hydro-dipped carbon for the carbon texture at a sane price, or real carbon fiber when nothing but the genuine weave will do.
What Sets It Apart
GT350R Aero Profile
Shaped after Ford's GT350R Performance Package skirts — a low blade that channels air along the rocker instead of letting it spill under the car, tightening the side profile and sharpening the stance.
Four Finishes, One Part
Matte Black ABS, Glossy Black ABS, Hydro-Dipped Carbon Fiber, or genuine Carbon Fiber. Same proven fit across the board — choose the look and the budget, the mounting is identical.
Built To Take The Road
ABS panels flex instead of cracking over driveways and speed bumps; the carbon options add the real weave and a premium hand. Pre-drilled mounting points line up to the factory rocker.
Bolt-On, No Cutting
Mounts to existing points along the lower door and rocker — no trimming the body, no permanent modification. A common-sense install most owners knock out in an afternoon.
