SPLITTER AND FRONT WHEEL WAKE INFLUENCING GROUND EFFECT

Utilizing this available space ahead of the front wheel where usually it is flat. Guiding vortices to seal the floor with the front wheel wake. This will also create a vortex that is as low to the ground as possible making it even more effective

The idea is the same on how some aerodynamic design is done to seal the floor on racing cars where there is an opening with turning vanes on them that forces an outwash at the same time create vortices. These can be seen on the frontal opening area of a Formula One car's side pod floor and other single seater racing cars sidepod

From the splitter tip, a subtle ramp angle is created into an opening space then abruptly closes, this is where the turning vanes are
