self leveling suspension ride height

1987 560 sel Not sure if self leveling suspension is working properly. Car is very tight and does not bounce. However it sits very low and the wheels have heavy camber. Bought the car 6 mos ago and am trying to return it to stock specs. Any way to adjust ride height????

It's "self Leveling" or it should level according to road conditions??

Its not just the back of the vehichle that sits low it is also the front. If the front suspension has somehow been altered, I would imagine that the suspension in the rear would level according to the height in the front. Im curiouse if there is any way someone could have altered the front(without cutting/lowering springs)I know on some trucks you can lower and raise the vehichle by loosening and tightening the torsion bar. Is this a way someone could have lowered this suspension?

Let's put it this way, most anything can be done, if someone knows what they are doing and how to do it. So to answer your question probably.
