I want to be able to adjust load ride hight ideally from the drivers seat or worst case scenario from the hatch.
I work on industrial pneumatics so plumbing in a couple of air bags is nothing.
I don't see how adjustable air springs are complicated. Use the same shocks, same springs, stuff air bags inside the springs, add a small compressor and a regulator then some air lines to connect it all together.
Yeah I am not trying to raise the car. I have 0 desire to do so. I might air up the springs to see what the ride hight is a full pressure.
But if I apply force to the spring, say with an air bag in side the coils, then hookes laws tells us that the spring will stretch.
The surface area of the ends of the spring are about 28 square inches, if the springs are 6 inches inside diameter then that's about 2,800 pounds of force with 100ps in the air bags.
Divide force by the k constant for that spring and you get the new length.
