That huge notch in the frame rail for the tie rod is a BIG red flag to me. By the time the lower control arm approaches parallel with the ground, the tie rod will almost touch the frame, even with the notch. Something needs to be done to move both upper and lower control arms lower on the frame rails, to allow approximately equal up and down travel of the control arms, with weight on the wheels and the springs compressed. I believe some major structural modifications are going to b required before the geometry gets right.
