I'm sure there's someone here who could work out the torque cause by
1g
spinning about an axis of 6-10cm at 1000+rpm ?

compared to the out of balance on even a balanced roadwheel, tiny.
Compared to the vibration caused by travelling down a road,
imperceptible. A non issue.


Besides on many cars there isn't enough clearance for the worm gear.

might be a problem in those cases


I would not choose iron wire, as it cant put anywhere near as much
retaining force on without cutting into the plastic rubber.
