just delving into physics in blender for the first time. I have a car following a path, everything's set up, drivers turning wheels based on the evaluation time, but one thing I'm struggling with is getting the car body to move up and down a little less than the wheels when it goes over a bump (to emulate suspension).

I have two empties following the path, one for the front wheels and one for the back wheels, and then I've parented the front wheels to the front empty, and the back wheels to the back empty. I've also parented the body to the front empty, and used a track to constraint so it always points towards the back empty.

I've tried making the body an active rigid body and the wheels passive rigid body, and then connecting them with a spring constraint, but as soon as I do this the body no longer follows the wheels (presumably parenting and physics dont work together?).

What's the best way to do this?
