Even at very low speeds (25 km/h = 15 mph) something's happening because raindrops dripping off the front lip of the hood get blown back toward the windshield, that didn't happen before the grill block. A rule of thumb says that above 60-80 km/h (36 - 48 mph), depending on the car, aerodynamic drag becomes larger than other drag, but that means that below that it's still up to 50% of total drag.
And raising the tire pressure helps, too.

Wow, Im sold on areodynamic mods now.
Most of my daily commute (40 miles daily total)
is 40 to 50 mph. I need to get started on the front air dam,
and complete underbody pannel.
