Set your ride height and check it from front to rear as well as side to side.
When you are happy with it you need to get you a pick or small hex wrench.
With the car set at eye level on a table move it so the front is facing right at you.
Take your pick and lift the center of the chassis until one of the wheels (either right or left) comes off the ground. Adjust the droop screw of the other wheel to come off the ground at the same time. Now you are balanced right to left.
Do the same for the rear. Once balanced you can measure the ride height of the chassis for both front and rear. When you pick up the chassis you can measure the droop value by measuring the chassis when the wheels just come off the ground.
In general a buggy will be more aggressive entering a corner with a lower ride height in the front than the rear. It will be more stable if the chassis is level. It will be planted in the rear and have a slower steering response if the rear is lower.
Most racers try to run max travel (max droop value possible without binding your drive train) for off road. I am an advocate of running minimal travel (less droop) to keep the car closer to the ground and out of the ruts.
If you run a little more droop in the rear than the front when your chassis is fully lifted it will be a good place to start.
More droop in the rear will give you more steering in but it will take your car longer to transistion in and out of corners.
More droop in the front will make the car easier to drive. Less droop will make the car have faster responses to steering input.
Play with it. It is a very useful setting.
