Ford Mustang S197 GT-R Widebody Aerodynamic Kit 2005-2009

Transform the stance, performance, and aerodynamic efficiency of your Ford Mustang S197 (2005–2009) with the APR Performance GT-R Widebody Aerodynamic Kit. This 10-piece package delivers aggressive styling while improving downforce, grip, and high-speed handling.

The GT-R Widebody Kit increases the front stance by +45 mm per front fender and +50 mm per rear fender, allowing for massive wheel and tire combinations — up to 20” × 9.5” with 285/30/20 tires in the front and 20” × 12.5” with 345/25/20 tires in the rear. This expanded width supports improved traction and enhanced cornering stability on both street and track.

To further optimize performance, the kit includes a carbon fiber front wind splitter / undertray, designed to reduce lift and increase front-end downforce. For drivers seeking even more aerodynamic balance, the kit can be paired with the optional APR GTC-500 Mustang-Spec 70” adjustable rear wing, which adds substantial rear-end downforce for greater stability.

Each component in the GT-R kit is engineered for precision fitment and built from lightweight, durable materials that maintain the Mustang’s muscular aesthetic while improving performance characteristics.
