Ford Mustang 5.0 GT Widebody Aerodynamic Kit 2010-2014

This item is made to order, normal lead time is 4-6 weeks.

The APR Performance Widebody Aerodynamic Kit for the Ford Mustang 5.0 GT (2010–2014) delivers both aggressive styling and race-proven aerodynamic performance. Designed to widen the vehicle’s stance and enhance handling, this 10-piece kit allows for wider wheels and tires while improving overall stability at high speeds.

Each component is engineered for precision fitment and aerodynamic efficiency. The kit widens the front and rear stance by +50 mm per side, allowing for massive 20" wheel setups — 20 × 9.5" with 285/30/20 tires up front, and 20 × 12.5" with 345/25/20 tires in the rear.

To further enhance stability, the kit includes a carbon fiber front wind splitter/undertray, which reduces front-end lift and increases downforce. For maximum track performance, optional APR GT-250 71" Mustang-Spec Adjustable Rear Wing and rear diffuser can be added to balance the aerodynamic load and deliver exceptional high-speed control.

The result is a Mustang that looks as powerful as it performs — aggressive, planted, and aerodynamically efficient.
