Physics are always a major headache - mine are pretty hacky and cut a lot of corners, such as ignoring trees or preventing the car from flipping. I only height-test the wheels, progress them independently, and then resolve the chassis position from that. It's not terribly physically accurate but it gets the job done, and is pretty cheap!
