The lower bar level to the ground is all relative. If the car has a couple degrees of rake it will move the front pivot. Raising or lowering the front or rear of the car will move the front pivot. It doesn't matter if the height is changed by tire diameter,torsion bar adjustment, or coil over mount hole selection. As you can see plenty of adjustment is available along with the front ladder bar mount hole selection. personally I think that shock selection and adjustment are the keys.
