Finished redoing my grille blocking using foam insulation. Now it can easily be adjusted based on weather and driving style. Modified my lower grille block to just cover the fog light area, and returned to the silver/gray color since the black looked too tacky in person.

As you can see, the grille blocking is easily removable.
Next step, rear wheel spats, and maybe experiment with partial front wheel skirts!
