Front suspension set up and wheel alignment

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.
Did you mean binding at the LCA to K member pins? Because usually there is talk of binding at the strut rod heim joint near the front of the K member. I have installed the PST greasable pin kit with poly bushing in the LCA. I was thinking I could shorten the strut rods just a bit (1/16" ??)from the stock ones without binding and to be sure they were actually not longer than the originals.
