i then created a root handle to control the movement of the rig overall moving this moves the drift and steering handle.















the blue circular handles are for the suspention of the truck, the more i move them on the line the more the "spring" reacts.













i then linked the wheels and truck body again to the rig, instead of the supenstion dummy i linked the body to the momentum dummy to allow me to use the handle ontop to control the position of the body.








an example of the supension working.
