Right now, the air in compressed and accelerated as it goes from the chin area to a narrower area (lower) near the axles. If I lower the chin down a touch, the air will not compress because the nose pan will be level due to lowering the chin.
Does that make sense?

Ah,since the plan is top lower,get a scrap piece of cardboard,take a protractor and create a 16-degree template,short side as tall as your bumper bottom.
Slide it under the car until it contacts the front tires.
The line of the hypotenuse of the angle describes the 'clearance' elevation of which no portion of the car can be below or else it will be struck by things civil engineers design.
As to 'compression,' that actually doesn't begin to occur until your going about 250mph.
A proper chin spoiler will shear off the airstream at the lower edge with no velocity increase,and send the rest of the air over or around the nose.
