Everything has to be taken on a case-specific basis.
I would recommend you maintain standard ground clearance. And I'll get in trouble for saying it.

No trouble from me Aerohead. I agree; you take something away and it gets added somewhere else - or so it seems with aerodynamics - hehe.
The link shows us how the pro's do it
One can see that they still let a lot of air in underneath the truck, but it's nice to see how the front air-dam then drops in front of the wheels to get air going around-, rather than 'stuck' in the wheel-wells. Hence, the designers and engineers try to get the airflow over, around and under as smooth as possible whilst trying to increase the total frontal area as little as possible in the process.
