Raise the car up, if you don't have GC's, loosen the two perches by turning the lower one clockwise, and turning the upper perch counter-clockwise. Then just keep turning it until you get the desired height. Then make sure you tighten the perches against each other so they don't move while you're driving.
It works best if you jack up the front/rear of the car for the side you want to adjust (versus jacking up the side of one wheel). You might also need to remove your rear wheels to adjust the rear.
