Getting requests for info about the wing we are using on the ND.
This is the APR GTC-300, with width measurements specified by us so the pedestals fit on the ND trunk lid. You can find it in our store here:APR GTC-300 Carbon Fiber Adjustable Wing
The GTC-300 is what's referred to as a "3D wing" because the shape of the wing changes across the width of it. This design favors being placed at the rear of a typical sedan shaped car; the center section of the wing is tilted less where the air is coming from over the top of the car at a downward angle, and the outer sections of the wing are tilted more where the air is coming around the side of the car at a more horizontal direction.
Data below from APR. AOA refers to Angle of Attack (the angle of the wing). The below CFD tests were done in a "free stream" which means that the airflow was linear across the whole width of the wing. This means these numbers aren't entirely representative of the downforce/drag values you will get in the real world with this wing mounted behind the roofline of a car, but the data still helps to give an idea of the forces that the wing can generate. At an educated guess, I would expect that the values from the test below would all be slightly higher (more downforce) in the real world because the effective angle of the center section of the wing as it relates to the direction of airflow coming down over the roof of the car is greater than is shown in a free-stream test.
Note that the forces are presented in Newtons. 1 Newton = 0.225 pound-force. So, with the wing set at the most conservative 0° angle, at just 80mph we already have 150 lbs of downforce. At a more aggressive angle of 10° at 120mph we have 450 lbs of downforce. Keep in mind these are free-stream numbers, so it's very likely we are seeing more downforce than this in the real world on the back of a car.
