So, I don’t know much about cars, but I generally expected for that part to be flush with the body. Is there any reason for there to be a grill like thing in front of the front door?

    Its probably for brake cooling.

    There’s a high pressure wave that builds up in front of the wheels that wants to be released by putting a grill in front of them so less air gets pushed under the car, because if that pressure wave were directed under the car then it would reduce the amount of downforce being generated by the Bernoulli effect.

    AFAIK, grills behind the wheels will actually reduce the downforce of a vehicle by allowing more air under the vehicle, increasing the pressure, but its a trade-off that can be made to regulate brake fade when trying to slow down from very high speeds.
