On the little knob with the slot for your screwdriver there should be two little white marks kinda making an arrow head shape with the slotbeing the body of the arrow, this should be pointing at the # setting you want. 5 up front 4 out back is what i generally have it set too.

What are the benefits of having adjustable control arms, I've always wondered.
