APR makes some nice wings, they are used throughout SCCA, NASA, World Challenge, Grand Am, etc.
I sell a wing that is SCCA GT legal, I do a carbon version and Fiberglass version, the wing comes with end plates and you could cut your own as well, plus wing mounts. According to the calculations of my aero guy at 150mph it will generate around 400lbs of negative lift with a drag rating of under 40lbs. I installed one on a GT2 RX7 and we ran it at just under 15 degrees for the first test session and the driver complained about the steering getting light at top speed. We had to back it down slightly to balance out the car with the front splitter. Driver liked it better with it down around a 10degree angle of attack. |

wind resistance being non linear and what not....an AX wing should be huge ALA Ury914 or sprint car type with steep angle of attack and can be mounted lower on a non windshield car that will not be drafting in traffic.

QUOTE(Britain Smith @ Oct 18 2011, 01:40 AM)  Got any picture Brett? How much downforce does it make at 60mph? -Britain Yup, see attached. I don't think I have a close picture of the wing itself though. I built the mounting system according to customer request. He wanted to make it removable to so he could keep running HSR. I made the end plates significantly larger than the spec plates because we were running in an unlimited class. My recollection was wrong, there is only a 3.24lb drag penalty, at 150mph it will generate 475lbs of negative lift at a 10 deg angle of attack. I can't find the chart for the wing data, so I don't have the graph of numbers through the speed range. If your using it for Autox, I would look for something bigger and just accept the drag penalty. Something in a multi-plane, look at the Unlimited cars, copy their setups. They will be really effective at parking lot speeds. Attached thumbnail(s)

Mistak's wing is the only one close to legal in SCCA AX out side of A Mod.
