You need to turn torsion bars. front and rear.
Very briefly, you need to take torsion bars from lower arms and rear brackets, set up height that you want to achieve and put torsion bars back in place. And be prepared to repeat process few times (even more than few) until you reach height you want
Angel once opened topic where he explained how to set up height of the car at front.
At rear you need to take of torsion bars, set up height of rear arms that you want, and then simply turn torsion bars until you can put them back in splines.
And again be prepared to repeat process until you are satisfied with height.
In whole process biggest issue could be removing torsion bars as they often get stuck from years of use, rain, snow and salt on the roads.
