MAZ Muscle GT4-R GTD Fenders - Dry Carbon Fiber (MAZ-24-GT4R-CF) - 2024-2026 Ford Mustang
Transform the appearance of your 2024-2026 Ford Mustang with the MAZ Muscle GT4-R GTD Dry Carbon Fiber Fenders. Inspired by the aggressive design of the Mustang GTD, these S650 fenders combine 100% dry carbon fiber construction, functional venting, increased width, and direct bolt-on installation for a performance-focused upgrade that delivers both form and function.
At approximately 0.85 inches wider per side than the factory fenders, the GT4-R design provides additional room for a more aggressive wheel and tire setup while creating a wider, more purposeful stance. Functional vents are incorporated into the design to promote airflow and heat dissipation, while the glossy clear coat showcases the dry carbon fiber construction.
100% Dry Carbon Fiber Construction
The GT4-R Fenders are constructed from 100% dry carbon fiber with a focus on weight reduction and consistent fitment. A glossy clear coat finish highlights the carbon fiber construction while delivering the premium appearance expected from a high-end S650 exterior upgrade.
Approximately 0.85 Inches Wider Per Side
MAZ Muscle designed the GT4-R Fenders to extend approximately 0.85 inches wider per side than the factory Mustang fenders. The additional width creates a more aggressive stance while providing additional space for enthusiasts looking to run a more aggressive tire setup.
Functional Venting
Integrated functional vents are designed to promote airflow and heat dissipation rather than serving as styling elements alone. Combined with the GTD-inspired body lines, the vented configuration gives the S650 Mustang a purposeful race-inspired appearance while adding functional airflow management.
Direct Bolt-On Fitment
The MAZ Muscle GT4-R GTD Fenders are designed as a direct bolt-on upgrade for the S650 Mustang with no modifications required. This allows the wider, vented fenders to integrate with the vehicle without the fabrication commonly associated with custom wide-body components.
