As I'm prepping for race season, I'm working with a trainer at they gym again. He changes up my routine and pushes me harder than I can push myself. One of the exercises he has me do he calls the "renegade row". Basically I'm in a push-up position with feet a little more than shoulder width apart and I have a kettle bell in one hand. The movement is basically keeping your body as flat as possible while rowing the kettle bell. And then it hit me. This is a good way to explain how spring height adjustments "move" the weight around on a car.
As you lift the kettle bell, the opposite side foot gets lighter, the opposite hand gets heavier, and the same side foot gets heavier. So by doing this movement yourself, you can figure out what way to move the spring to increase or decrease loads on the corners of the car and "feel" the effect yourself to help understand what's going on.
Anyone else have similar tricks?

I like the idea of using paper, I have seen the sheets of paper for corner weighting pop up a few times, I think that might be a good way to help visualize what is going on, maybe jack up one side or an another and see how it all moves
I just explain it by using the analogy of a table with one short leg. Diagonal weight transfer is easy to understand there, as is the idea of the weight being carried by the "tall" corners.
Here's another real-life example for the Canucks: portaging a canoe. If you're carrying with a friend and he pushes up on one gunwhale, you'll have to do the same to the other side. If this keeps up, you'll end up getting into quite a shoving match.
In reply to Keith Tanner:
I used to portage canoes alone for that very reason!

I use the "picture a four-legged table sitting on a mattress" analogy. All four legs are touching the mattress, yet the weight each is carrying can be very different.
