User assumes full responsibility for ensuring proper installation as intended. Professional installation by well-qualified personnel is highly recommended. The vehicle applications shown above are intended to work as a complete system when installed onto original vehicle body parts (i.e. trunk lids, hatches, etc.). To insure proper function and reliability, APR advises against modification or substitution of any component of the intended installation. Any modification or substitution of the airfoil, side plates, pedestals, mounting bases, mounting brackets, or hardware included with the wing kit may create unsafe operating conditions and ultimately cause this system to fail. Substitution of original vehicle manufacturer parts needed for the intended installation (i.e. rear trunk lid or rear hatch) with non-original parts may also create unsafe operating conditions and ultimately cause this system to fail.
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.
Each GTC Series airfoil is composed of lightweight and durable carbon fiber reinforced polymer (CFRP) composite materials. These airfoils contain pre-pregnated woven carbon fiber sheets for superior strength and low weight. All CFRP airfoils are made using pre-pregnated composite manufacturing processes (i.e. high-temperature autoclave and vacuum bagging) in high-quality aluminum billet molds.
Supporting the airfoils are 10mm "aircraft grade" 6061 billet aluminum pedestals that come in a flat black powder coat finish.
Center section to outer section angle difference: 12 degrees

Gurney flaps are now available for all of APR's GTC-series (200/300/500) wings. These are super lightweight, made using pre-pregnated carbon fiber processes, 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.
Various wing accessories including risers, flaps, wing plates and other items are available. Please ask!
