The "length" of the center link hasn't a bit to do with anything, other than the the pivot needs to be the same as the lower control arm so when the knuckle (spindle) goes up and down the inner/outer tie rod assemblies have the same arch. If they have a different arch they effectively will have different "lengths" than the control arm and thus you will have "bump steer".
So you are saying the location of the outer tie rod end on the spindle centerline through the ball joints , in for the Ackerman in the rear, out for Ackerman at the front does not affect the center link length? And the height of the steering arm on the spindle above the lower ball joint has no affect on the tie rod length, and the center link length? And the upper control arm inner pivot location, versus the lower control arm inner pivot have no affect on the center link length? And the height of the center link vs the outer tie rod end, and the inner control arm inner pivots has no affect? Just that the outer tie rod is the same length as the lower control arm, correct?
