Just the steering
The brakelight animation plays when you brake. The beginning of the animation is off, the end is on. It must be called "brakelight".
For the spring animations you need to animate every hub, the beginning of the animation is when fully compressed, the end is when fully extended. Every hub needs it's own animation which are called "springX".
The animated spring must be as long as the spring datablock or longer when fully extended or the animated part will stop at whatever height the animation stops.
