Me in aero expert ☺️ mode, the vents at the top of the front guards would work but lots of drag and the rotating wheels would tend to pull air away from them. Much better to have vents behind the front wheels for less drag and the wheels would act positively. If there were diffusers  in front of the wheel area they should work better too.
