Ford Mustang S650 Dark Horse Rear Trunk Wing Gurney Flap Spoiler 2024-Up

Upgrade the rear aerodynamic profile of your 2024-Up Ford Mustang S650 with this Dark Horse style rear trunk wing and gurney flap spoiler system. Designed to replicate the factory Dark Horse performance aero geometry, this wing package enhances the aggressive rear appearance of the Mustang while maintaining OEM-level fitment and trunk lid alignment.

The spoiler features a modular wing design that distributes aerodynamic load evenly across mounting points, improving stability and structural strength during high-speed driving. Integrated above the main wing plane is a performance gurney flap wickerbill that helps increase airflow separation at the trailing edge of the spoiler, improving aerodynamic efficiency and rear-end stability.

Constructed from high-strength automotive-grade ABS plastic, this spoiler system offers excellent durability, impact resistance, and thermal stability. The professionally finished glossy black surface provides a clean OEM+ appearance that complements factory trim, rear diffusers, and performance styling elements across the S650 Mustang platform.
