In a rear wing how do you find camber%. I have new aerodynamic software and It needs to know wing camber% to do the calculations. thank you.
The camber it is most likely looking for is the following ratio:
[distance of chord line from camber line] / [chord] = xx%
where the chord is the direct measurement from the leading edge to the trailing edge, and the camber line is the "best fit" line, following the curve of the wing. This measurement must be taken at max thickness (since you could otherwise get different results as the camber line becomes closer to the chord line).
Since you have the wing in hand, it will be quite difficult to get the camber. I suggest contacting the manufacturer, which should have this information in their database. You should also remember that the angle of attack is dependant on the airflow, not measured from level ground.
Of course, if this is a wing from a body kit manufacturer like Wings West, I can pretty much guarantee you that it's not going to do much of anything but look good on your car. Quite simply, if you can easily bend or flex the wing, it won't stand up to the high wind speeds that are possible of creating reasonable amounts of downforce, and will simply deform to the airflow.
