considering our cars come with air shocks (93 el) is it posiblle to control the leveling of them. such as an external controller like on cars with airbag suspension. i assume that a certain voltage gets sent to pcm that turns on the compressor, and bleeds excess air out. so is it possible to mimic those signals? so we would be able to raise and lower the body at will?
If you could find the suspension control/height sensing arm, which is attached to an encapsulated variable resistor/rheostat, you could simply duplicate that resistor setup somewhere else in the car with a control knob. Just don't get crazy and overpressure the system which would blow up shocks and air bags.
The present shock/strut setup will not allow that sort of movement. In order to so extensively modify the suspension to accomodate a 3" drop you'll need a custom shop that specializes in such work. I doubt you'll find much help in here because the idea is far from ordinary, and the work entails a complete redesign of the suspension geometry.
