Two types of Pro-touring suspension options are "static" or "active". Static suspensions are adjustable and consist of shock absorbers, springs or coil overs, anti-sway bars, and a shock tower brace.
Active suspensions provide a higher degree of adjustability and consist of a combination of static components and the use of air bags, an air compressor, solenoids, and a controller. Although a static suspension set up is adjustable, the active suspension platform allows the driver "on the fly" adjustment capability.
