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.

Spanning 59.5 inches and a height of 10 inches, the GTC-200 adjustable wing offers the perfect amount of downforce for midsize and compact cars.
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.

Gurney Flaps
Gurney flaps are now available for all of APR's GTC-series (200/300/500) wings. These are super lightweight, made in carbon fiber using the pre-pregnated carbon process, and conform perfectly to the contours of the GTC-series 3D airfoils. They are easily attached using the included double-sided tape.
The Gurney flap (a.k.a. wickerbill) is an aerodynamic device that was originally pioneered and developed in the 1970s by a racing driver named Dan Gurney. Unbeknownst to his competition, this device was used to increase downforce while minimizing increase in drag. He found that not only did this device increase the lift/drag (L/D) ratios, it also increased the stalling angles (so he could operate the airfoils at greater pitch angles). It took a few years for everyone else to catch on to its purpose, and now, the Gurney flap (or similar device) can be seen in race cars and even airplanes all over the world.
