2009-2012 BMW Z4M Coupe GTC200 Spec Rear Wing
| |||
Add style and performance to your 2009 2010 2011 2012 BMW Z4M Coupe with this GTC200 Spec Rear Wing. 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. Each GTC Series airfoil is composed of lightweight and durable carbon fiber reinforced polymer (CFRP) or fiber reinforced polymer (FRP) composite materials. CFRP models contain pre-pregnated woven carbon fiber sheets for superior strength and low weight. FRP models contain woven pre-pregnated glass fiber sheets for high strength at reasonable weight. All CFRP and FRP airfoils are made using pre-pregnated composite manufacturing processes (i.e. high-temperature autoclave and vacuum bagging) in high-quality aluminum molds. Supporting the airfoils are 10mm "aircraft grade" 6061 billet aluminum pedestals that come in a flat black powder coat finish.  Gurney flaps are now available for all of APR's GTC-series (200/300/500) wings. These are super lightweight, made with carbon fiber using the pre-pregnated 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.  | |||
