Well, I got something basic working at least. Ignore the extremely shitty test models.

I'm using the jiggle bone addon for the bounce (which has its own problems), though I think I could do the same with cloth springs, and probably better too. Though I don't know how I'd get them to stay standing up.

Basically it's just some empties with a shrinkwrap constraint to follow the ground, some wiggle bones constrained to follow the location of the empties. Then the bones deform a plane's 4 corners. On top of all that another empty is shrinkwrapped to the plane, with the "align to normal" box checked. So that the 4 points change the face direction, and therefore change the way the empty rotates.
After that it's just a simple matter of making the car body the child of that empty.
I'm definitely going to change the bones to cloth springs though, so they can have interactions with the physics system.

The terrain causes the suspension to spring the body, but I don't know how to get the body to interact with the springs. Since the car body would have weight and inertia to compress and stretch the springs.
