Not having the technical background and expertise. might some one clarify:

I had a Austin Healey 100-6 and then a XK-E, both with factory spinners/knockoffs that were not factory safety wired. I do not recall any recommendations to safety wire.

A tool was placed over the knock-offs for use with the hammer rather than hitting the knockoff directly. Recommendation was to retighten after a few miles and the knockoffs were marked right and left.

My understanding, the knockoffs originated to facilitate speedy tire replacements for race cars prior to powered devices to remove the single or multiple nuts. When replaced, the knock-offs were not safety wired during the race,

With a very quick check of the Dayton Wheel site, does not appear to mention safety wires for their spinners/knockoffs.

What would be the difference in the knock off wheels mentioned on this Thread and the Austin Healey and Jaguar wheels ?
