The air dam is concaved to feed air sideways to the barge boards, which admittedly might should be bigger.

Based on observing OEM solutions, the outlet should be 1 inch across the middle third of the wheel and the inlet can be any shape with a larger area to create a converging duct.
A problem might arise when there's any crosswind component attacking the nose.The sharp edge may trigger separation,whereas the original radius'd edges would not.There would be a low pressure leeward moment ahead of the front axle inducing yaw, which you'd have to correct for constantly with the steering.Not a problem on a closed race course.
