adjusting high of the car

[Alexander]

I want to know how to adjust the rear high of the renault 4, by inner suspension mounting,or only by adjusting the outer rear mounting(I think that outer suspension mounting is only for adjusting vertical alignment of wheel not high of the car)?
Is there possible if one side of outer suspension mounting is deattached,to produce car lean on the side?

I believe ride height can be adjusted by adjusting the torsion bars. How easy or difficult this is I don't know.
