air ride can work great, the problem is that most set-ups run either too big of bag, too small of bag, wrong shocks, wrong pressure....or E: ALL OF THE ABOVE.
a proper designed air system can be taylored to YOUR specific needs, at the push of a button and some fine tuning of shock adjustments...you can have a ride just like YOU like it, i do agree with the STREET car comments, meaning it does handle "ok", great for the street...not the track.
shockwaves have enough choices that getting the right size "bag" is as simple as a tech line away(actual corner weights will help), and with single/double adjustments available, the shock tuning is right there waiting.
i think for a cruiser street car, air ride is the ONLY way to go, rides great, looks cool parked, and has a comfortable cruising altitude for the nations less that perfect roadways.
i say ditch the leafs, mini tubs, 4 bar and shockwaves...IF its a cruiser....if its a track whore...bring it to my house and i will "trade" ya an A-body
