Having had my car for a while now I have found that the windwings and the windshield angle do the most for controlling the wind. My wings are substantially larger and follow the contour of the body. I found that the wind coming from the bottom of the wing over the top of the door is the biggest "blower". The wind coming from the back in my car ..without rollbar or webbing is absolutely livable
