i installed mine initially without the torsion bars in, let the control arm drop naturally then lifted it up to where the ride height would be roughly, set the strut rod to the length that put the arm where i liked it fore/aft, no binding. then move the control arm up and down to make sure it doesn't bind.
you want to get super picky, get the car back on the wheels, drop some marks with a plumb (i used the rear torsion bar sockets and the front bolt on the lower ball joint) and make sure both side are the same...
