To lower you have to go softer and to raise it you have to go harder. This is the exact opposite of what people do with real springs (for good reason).
Also, air springs are by definition extremely progressive (non-linear). Again the opposite of what is desirable in a "performance" application. As the OP points out he needs to crank the damping up and lower the car to get best lap times. This is more nonsense from a performance or ride quality point of view.
An air suspension that supplements a conventional spring to adjust ride height makes some technical sense in some applications, because the non-linearity introduced by the air spring is small relative to the total spring rate.
A pure air spring suspension has no place any car worth driving on a track.
I am reminded of a cat that drags its ass on the carpet after having a crap when I see a car on deflated air springs. Correction, I am reminded of the crap it leaves on the carpet.
