Give your Mustang a new look while lowering the overall weight of your Mustang from your factory spoiler with this 100% CARBON FIBER GTC500 WING SPOILER.Spanning 70 inches, the GTC-500 Carbon Fiber Adjustable Wing is the largest wing available for the Ford Mustang in APR's catalog. All GTC Series wings feature an aerodynamic 3D designed airfoil shape to obtain the optimal balance of downforce. This design allows for a reduction in drag, yet maintains an ideal level of downforce. Computational Fluid Dynamics (CFD) analysis was performed on this wing to support validation of its aerodynamic design.
