with our two cars the wing angles at the factory setting was at .5 degrees tilted up in the front.
with a little pressure pulling back on the wing it easily moved to 1. degrees up in the front. pulling the wing back harder it went to 1.5 degrees up angle in the front measuring the wing in the center.
a leading edge of a wing should be facing straight into the flow of air. on many cars this isn't also that a wing angle is at zero angle on a horizontal plane.
on some cars as the airflow over the roof and down the rear glass the airflow is coming down on a downward angle.
I would love to see a better simulation of the rush sr airflow over the car to see just how it's hitting the leading edge of the wing. the best I will be able to do is setup a pitot tube. from the sim it looks like the airflow is hitting the wing straight on a horizontal plane????
by setting the wing at IMO a 5 degree down angle being a twist wing is that the two outside edges acted like cups putting excessive pressure at the weakest spots of the wing. it was also basically putting the wing into a stall having the airflow on the underside lifting off the wing.
all this is a total hypothesis with out having enough data to support anything.
