The biggest part is to get the tie rods parallel with at least your lower a arms. That will get rid of some of the toe in issues. The width of the frame is going to make it nearly impossible to eliminate all of toe in problems. Because the arms and tie rods don't travel in the same arc, the tie rods will push the toe out when the suspension is compressed. It's why almost all of the manufacturers are building their quads with such a narrow frame now. I'm actually working on a couple things right now to try and compensate.
