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.
Great downforce with very low drag
All GT Series wings feature an all-new, low-drag, aerodynamic 2D designed airfoil shape. The "2D" design allows the wing to maintain a consistent level of downforce across its entire span. Computational Fluid Dynamics (CFD) analysis was performed on this wing to support validation of its aerodynamic design. Click here to see the CFD data.
Each GT 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.
The GT-250 includes these special features:
- 71" span, 10" chord
- Suitable for installation on factory original trunk lids
- 6061 "aircraft grade" billet aluminum pedestals, with flat black powder coat finish
Gurney flaps are included and pre-installed with every GT-250 wing. These are super lightweight, made using pre-pregnated carbon fiber processes.
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.
