I agree with Chuck. The amount of loosing force that the wheel experiences from motor acceleration is insignificant compared to the suddent anti-rotational impact force placed on the hub when the car hits a pothole, curb, or obstruction. Having the spinners tighten in the direction of force from a pothole hit is the advice I have always heard.

Also, I hope I am not sidetracking this thread, but besides safety wire here are a few pictures of spinner lock methods I have seen. If someone knows a source for this sort of hardware, I would appreciate the reference.
