I'm not sure what other sway bars will work with this kit yet but the ball ends with set screws are part of the shock components set.

It comes with a 1.4MM and a 1.3MM for the front/rear. works really well on medium traction surfaces with some bumps.
For VTA you won't be able to beat the Spec-R S1 I'll bet, not in price or performance unless you get the R1. I hope to have one of each soon!
