Headlamp aim is a determined drop at a set distance, 4" at 12' I believe? Flat ground, angle ground, doesn't matter as long as the 12' out is the same slope as the car is sitting on.

Uses only the rear control arm, it doesn't read the front. Meaning on a slope facing up, with the rear suspension under greater load, it would think there's weight in the back.
