E-mail this product to a friend

Spanning 70 inches, the GTC-500 is the largest aftermarket adjustable wing available. With its optimized 3D airfoil shape, the GTC-500 is perfect for high speed touring applications and supplies an ample amount of downforce without causing excess drag.

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. The results of this analysis are available here.

Each GTC Series airfoil is composed of lightweight and durable carbon fiber composite. Supporting the carbon fiber airfoils are 10mm "aircraft grade" 6061 billet aluminum pedestals that come in a flat black powder coat finish.
