I am struggling with vehicle connection points.
I have a set of wheels way below my chassis shape and every time I try to move them closer the whole vehicle shoots off vertically up forever! When it does this the wheels are positioned way above the bottom of the chassis, even though I've moved them a very small amount.
Can someone please explain the relationship between connection point and suspension rest length, centre of gravity of the chassis? The demos have magic numbers in them 0.6 for suspension rest length, 1 for centre of gravity offset, 1.2 for connection height, but I can't bring it all together to calculate my own.
