GTC300 carbon fiber 3D
Includes, stanchions, special Miata specific mounts hardware kit and instructions
This 61″ wing is about 2″ wider and 4″ longer cord than the GTC200. Recommended for V8 conversions, and forced induction cars making more than 300whp. Assuming your car is set up well to begin with, it may drop lap times by 2-3 sec on a 1:40+ road course. With this bad boy, you’ll start to feel a distinct difference in grip as low as 45mph. Turns that require feathering the throttle at 65mph might now be WOT. We recommended that you add significant front aero to balance it out, such as a 3-5″ splitter, air dam, canards or all of the above. For cars below about 180whp the GTC200 or GT250 will be a better compromise between downforce and drag.
Which size and how to tune it?
Always start with zero angle relative to the ground as measured in the center portion of the wing, add angle for the lower speed tracks or wet weather driving. The center portion of the wing should never be angled more than 10* positive (tilted forward) relative to the ground. The wing can even be set up for slightly negative angle up to about 5~8* (tilted up in front) for reduced drag and a bit less downforce. Never run the top surface of the wing any higher than your roof line. If running with no top, this is the wrong foil. You will want a 2D shape like the APR Racing GT250 or similar.
Technology and Construction
With a span 61 inches and a height of 13 inches, the GTC-300 is an adjustable wing that means serious business. The GTC-300 3D airfoil shape allows for optimal airflow that reduces drag yet supplies an effective amount of downforce. Computational Fluid Dynamics (CFD) analysis was performed on this wing to support validation of its aerodynamic design. The results of this analysis are available here.
Each GTC Series airfoil is composed of lightweight and durable carbon fiber composite. Supporting the carbon fiber airfoils are 10mm “aircraft grade” 6061 billet aluminum pedestals that come in a flat black powder coat finish.
