I think they look silly without upgrading the tire size atleast. (this one is a bit exaggerated because it has a body lift)

Diff Drop brackets are something you, or a shop would have to fab up. Ascinder built some for his rig.

As for the 10-12 cranks on the torsion bar, I think it depends on your definition of a crank. It's only a few rotations you need.

Also you should atleast get all of the urethane components (bump stops, sway bar bushings etc.) They're only around $120 for everything you need.
