Product Details
 
When it comes to racing, every second counts. APR Performance Adjustable Wings can give you that edge to achieve faster lap times. By reducing lift and increasing downforce, you can gain extra traction during high speed cornering. Although adjustable wings aren’t specifically a suspension component, they play a crucial role to the handling characteristics of a car. By adjusting the angle of attack on an adjustable wing, you can dial in the amount of downforce for better car control. This allows your car to have more or less oversteer characteristics, giving you additional control to tune the rear traction of your car. We can set custom mounting distances for most wing applications.

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.
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:
  • 67" span, 10" chord
  • Suitable for installation on factory original trunk lids
  • 6061 "aircraft grade" billet aluminum pedestals, with flat black powder coat finish

Optional Gurney Flaps Now Available
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 "dry" 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.
