I set my ride height first. Then I lift the end of the car I'm setting until the tires come off of the table. Measure again and adjust droop screws until the tire comes off of the table at the desired droop. Everytime you adjust ride height, you have to adjust droop. If not, your droop will decrease as you maintain ride height with tires that are wearing down.
Merry CHRISTmas to all!!
