Unipivots are generally designed to be as stable as that configuration permits. This means that ”lowering the tail end” increases downforce not decreases it as you have suggested.It isn’t clear what you mean here when you use the word "downforce." If you lower any statically balanced pivoted arm - regardless of bearing type - you will decrease VTF, all other things being equal. That’s just simple physics, and what I was trying to clarify.
