step cont arms or drop spindles....

I've been reading through this and I don't think I follow...either the step changes the steering pivot or it doesn't. You mention that nothing changes when stepping the control arm, then you say the tie rod angle does move up. That's a change in the pivot point along the tie rod arc of travel. I think vin63s photos clearly show the increase in the tie rod angle - that's a significant change in that steering geometry.

This illustraton shows two different control arms...the bottom image has the higher ball joint, but the arm itself is longer and has a downward angle that negates any height gained by the higher ball joint location.
