You can also experiment with taping/blocking any part of the grille as long as you can keep temps under control, best done with a front spoiler. Also keep in mind, any changes with airflow at the front, effects almost every surface that follows, hence the earlier comment of maybe also needing a rear spoiler/wing, but added control is likely your result/goal.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
