Spanning 71 or 74 inches over its optimized 3D airfoil shape, the APR Performance GTC-500 Adjustable Wing supplies maximum downforce in widebody sports and touring car applications.
The Downforce Balance graph (shown at the left) illustrates which areas of the vehicle this product affects.
There are three (3) areas: Front, Center, and Rear. The size of the red bar represents how much this product affects each particular area.
|Pattern||2x2 twill weave|
|Material||Pre-preg carbon fiber, 3K|
|Coating||UV-stable clear coat|
|Wing Span||70" w/ variable Angle-of-Attack (AOA) (center section vs outer section angle difference: 10 degrees)|
|Hardware||Stainless-steel machine screws, washers, and nuts|
|Mounting||6061 billet aluminum brackets/pedestals with application-specific bottom mounting bases|
The APR Performance GTC-500 Adjustable Wing features a 3D airfoil shape that is designed to produce balanced downforce across its span on widebody sports and touring car applications.
Each GTC Series airfoil is composed of lightweight and durable pre-preg carbon fiber composite materials for superior strength and low weight.
Aerodynamically-tuned side plates (aka end plates), included with every GTC Series Adjustable Wing, are critical components that help to ensure consistent airflow across the full span of the airfoil.
Supporting the airfoils are 10mm "aircraft grade" 6061 billet aluminum pedestals that come in a flat black powder coat finish.
Computational Fluid Dynamics (CFD)
Modeled in 3D and validated using Computational Fluid Dynamics (CFD), the APR Performance GTC-500 Adjustable Wing is designed to adapt to a variety of widebody sports and touring car applications.
CFD Data for the GTC-500 Adjustable Wing (Click to View)
Contained herein are the data and results of the Computational Fluid Dynamics (CFD) analysis that was conducted on the GTC-500 airfoil. This data illustrates how the airfoil performs in different conditions by comparing Downforce vs. Angle-of-Attack (AOA) vs. Speed, and Drag vs. AOA vs. Speed. This data will provide insight with regards to how and how much the airfoil performs with respect to these conditions.
To learn how to interpret and apply this type of CFD data, see sample analysis on the GTC-300 page.
CFD DATA (TABLES)
The following table shows the actual data that were collected from the CFD analysis. The numbers in the table are represented in Pounds.
The following image illustrates where and how the AOA is referenced. At 0 degrees AOA, the reference plane is parallel to the direction of the free air stream (the stream would travel from right-to-left in this image). This reference plane can be simulated by placing a ruler across the top of the center section of an actual airfoil.
CFD DATA (GRAPHS)
The following graph illustrates the effects that air speed and AOA have on downforce only. The higher the air speed and AOA are, the higher the resultant downforce is.
The following graph illustrates the effects that air speed and AOA have on drag only. The higher the air speed and AOA are, the higher the resultant drag is.
The following graph illustrates the lift and Drag Coefficient Ratio.
CFD DATA (RENDERED IMAGES)
The following image illustrates the pressure distributions across the surfaces of the airfoil.
The following image illustrates both the pressure distribution and streamlines associated with the airfoil.
The following image illustrates both the pressure distribution on the underside of the airfoil

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.
