GT Motoring | APR GT-250 2D Wing

GT Motoring is proud to announce we are now an APR Performance Dealer. The GT-250 is APRs newest wing profile, and their only 2D profile that is available.

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.

Supporting the airfoils are 10mm "aircraft grade" 6061 billet aluminum pedestals that come in a flat black powder coat finish.

Gurney Flaps

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.

Available in both 67" and 61" spans, for both the E90 and E92 M3s
