That's not the way the ride height is determined. It's done by measuring the the distance between the ground and the centerline of the lower control arm attaching bolt and the ground and the outboard end of the lower control arm, subtracting the shorter measurement from the larger one and comparing to the specification. This is done on each side. The torsion bars are adjusted, as necessary, to get the ride height within specs. If you change the ride height, it will affect the front camber, so a wheel alignment would then be necessary. A "proper" wheel alignment would include adjusting the ride height to spec. If you download a copy of the service manual, it will go into more detail and show a picture of the measurement points.
