TRACKBAR, anyone here run one?

This pic is what I was talking to:

With the wheel travel of a street car the delta in the spring's length is pretty tiny. The Wrap-Trap that I posted above uses a Ford truck radius arm bushing for the front 'pivot' and that coupled with the ideal placement of that pivot has enough give to handle the small delta from the much larger travel of the Early Bronco's springs.

ntsqd, That would handle axle wrap, but in that configuration, I'm not seeing how it'd mitigate side to side movement. The front of the mount would allow some mount of movement in any direction.
It'd almost have to have a bearing / sleeve arrangement at one end for vertical movement then some sort of cantilever ( like f1 suspension ) or slotted ( kinda like a leaf spring slider ) setup at the other to allow the length of the mounting points to change ( to account for movement arc )
Sorry if I'm not helping, I love the discussion, I'm a "gotta know why" person :D

Anyway, Back to the OP questions.
Who has one installed?
What handling aspects changed and to what extent?
Let's see 'em! ;)
