you just wanna turn that bolt on the far end...
just MAKE SURE you turn them the same amount of times, that way they dont get uneven...
your car should have at least 1 degree of rake towards the front...if not, you may have rear axle problems...
oh, and to give you point of reference, i cranked my bolts(a lot of people say bars but i think that is confusing because the bars dont turn much) 14 times to get about 2.5-3" of lift.... so if your looking to drop 1" in front i would crank them maybe 4 times??
also, make sure you crank them less times than expected, drive it around the block (over some bumps and turns) then re-measure...because they settle
