Over the New Year my Dad and I installed an Air Lift system. We used the Autopilot Digital Control system, which allows for maximum control over each wheel. The install was very straight forward but for us required a little more than just direct bolt on as said in Air Lifts directions. Overall it is a great system. The car handles and rides better than stock now. For install photos you can follow this link

Also if you are in the Dallas, Fort Worth area and would like to have this installed on your Camaro or any other vehicle. Kwik Kar Lube & Tune off of Central Drive in Bedford, Texas is an Air Lift preferred dealer.
