Front suspension set up and wheel alignment

Just read the instructions on installing the Hotchkis adjustable strut rods. It says, "Next rotate/thead the body in or out to the desired length. Shortening the strut rod can dial in more positive caster." Sounds good but how long to adjust the rod? I guess I will have to measure the old strut rod and go from there. I will be installing the Moog offset UCA bushings to get more positive caster. How much extra should I attempt with adjustment of the strut rods to move the LCA forward?
I've read in this forum several times that you should adjust your strut rods to achieve zero binding, and that adjusting them to gain additional positive caster can cause binding. If the offset bushings give you less caster than desired, the best solution is to use aftermarket upper control arms. You can get adjustable or those with more caster built into the geometry.
