Bolder fender flares, sharper transitions, and a stance that reads track car from any angle — inspired by the Mustang GTD program.
Properly cut louvers pull heat off the front brakes and engine bay — not just decoration. The vents do real work at speed.
No cutting. No modifications. Bolts to factory mount points on every 2024–2026 S650 Mustang trim.
Approximately 0.85 inches wider per side — plenty of clearance for an aggressive wheel and tire setup.
Dry Carbon Fiber at $1,499.99 — gloss-coated, weight-optimized, OEM+ finish. Fiberglass at $1,099.99 — ideal for paint matching or wraps where you don’t want the carbon weave showing through.

Made-to-order builds — carbon fiber bodywork, fabricated systems, custom finish work — run longer than off-the-shelf items because they're built per order. You'll get progress updates throughout the build.
