I personnally don't have Air-ride however I know a quality full-service restoration shop (one that wants and drives its customers to do what's right) - They recommend Air-ride highly. I have spoken with three of their customers and beyond the quality of the whole car they like/love air-ride. If you haven't already ... you should hit a Goodguys, Super Chevy, or some other event that they have a booth. You can feel and touch their products, sometimes they have a mock car and with out a doubt they can direct you to a customer's car.
Once again .. I'm just using old fashioned shocks and springs
