It may not show at this angle (never saw the car again) but the fences inside the wheels are angled outward the width of the tires. This example is sized to the max of the class racing rules. I can see it doing triple duty:
separate wheelwell and underbody flow
diverging duct for the underbody
open-sided wheel spat
My suspicion on the vette on the flats, there is a lot of effort there to gain rear DF with the least amount of drag within the rules, being getting HP to the salt is difficult at high speeds with OEM body shape. My guess, drag reduction was the lesser goal.
