You can also vary the damping rate and spring rate of just the bladder by changing material thickness/composition, geometry/folds, etc. The spring rate of an air spring is NOT just a simple function of air pressure. It is one variable in the equation but it is far from the only one. There is a lot more going on in an air spring than most people think, and to really sort one out you have to have a good working relationship with the bladder manufacturers, know what you want and what you want it to do, and then go do some data gathering & testing.
There is a "nominal" height & pressure range for each given air spring configuration, so given the corner weight of the vehicle and desired ride height you have to choose the proper spring for the application such that when at its intended operating pressure range it is at the right overall length for the intended ride height in that vehicle.
