In our hot rod shop air is the deal!!!!! Good ride, adjustable height, slam it at the shows, win, win, win. Good ride comes from good engineering, not by accident. About the concern of a leak, or bag bursting. You check for leaks, on the install, if you have a leak, fix it. I drive two of my own custom cars with air ride. One of them over 10years, it doesn't leak, and no burst bags. Don't be afraid, of what you haven't tried. Air ride is the way to go! Check out Air Ride Technologies web site we have a link to our web site from there site also.
