Air Shocks & drag racing, a good combination?

I have a 72 Chevelle which I take to the strip on occassion. I have a question which never crossed my mind until last weekend when I was at the track. Do air shocks help or hinder a car when launching? It seems to hook up fine but maybe I'm leaving something on the line.
Any input would be appreciated.

I've used them before in drag racing....used a separate line kit to put a bit more air into the right rear shock than the left. Sort of a biased suspension setup or preloaded if you will.

Coil spring GM cars have a nasty way of twisting up on launch because of the rear suspension geometry. An air bag or air shock mounted in tandem with a regular shock at the right rear helps to level the car out on launch. I had some old air shocks laying around, so thats what I used. I took the schrader valve out while street driving and made the air shock passive. Install the valve, add 60 PSI and race. Simple.
