little tip: for fast velocity action, e.g. spanking, disable the collider on the CUA (in it's physics object settings) and rather try to use a shape from VAM itself, e.g. the iscapsule, and hide it by setting it to "hide matererial" in its material/shader settings. that way, you get a invisible dummy collider that you can bind to the CUA control node, or animate in synch with the CUA.
