I agree with most of the above comments, however, if you choose a different car, say an A-body, the picture clears a bit. I am going thru a similiar game right now with my next project, a 70 chevelle and have made the following choice. I will use the AirRide system, but with a twist. I will have the ATS spindles just because I have been so impressed with them on my malibu. For an A-body, I feel the Air Ride system is the best choice and will be flexible enough to do drag racing and road racing good with some practice and trial and error with settings. I will know more soon.
