Racing Spec GT Series wings are designed to produce effective levels of downforce for high speed race tracks. With its single plane/dual element airfoil design, the Racing Spec GT Series Adjustable Wings provide up to 15 degrees of adjustment to the angle of attack. The Racing Spec GT Series wing airfoils are available in dry carbon fiber and aluminum. Supporting the GT Series airfoils are 10mm "aircraft grade" 6061 billet aluminum pedestals that secure the wing to the car.
