Actually John...you can adjust droop that way...that is how we adjust droop on pan cars. If you setup the shims so that there is a little bit of play in the spring then you will also have droop. When you lift the front end the upper arm and axle will droop even though the lower arm is static. The big difference being in a pan car we can shim the front suspension to account for the resulting change in ride height...but I don't know if you can do that on the FGX...it doesn't look like it can.
