No, just straight down, making sure the arm tubes clear the factory frame.
the reason the holes were moved back was to increase the Caster, now with that built into the arms not required.

Yeah, what he said!

Here is a pic of the procedure on one of my personal cars. At the end of the day your simply changing the relationship between the pivot point (Control Arm Shaft) and the Ball Joint. Weather you do it with a tall spindle (raising the ball joint) or lowering the pivot point (lowering the control arm shaft) the net effect is very similar.
