Technically the swaybar arms should be 'parallel' to the ground so the maximum leverage can be exerted on the bar, evenly, for both upward and downward movements. The adjustable links are meant to help achieve this setting, and could be used to 'preload' the swaybar in one direction (example, favoring a left turn over a right turn) to help prohibit body roll in one direction - but will be less effective in the opposite turn, like running a vehicle on an oval track that requires a 'stock' suspension. Rotating the arms upward will lower the kink, as stated, but limit the rotation to what just works to prevent contact for the best results.
