for years and many thousands of miles, i never safety wired my tri-wing spinners. I just tapped on them with my dead blow hammer often, to ensure they stayed tight. I have found as i am sure others too, that it you wack on the spinners with a lead hammer, that eventually you may create a problem when the wheel needs to come off. So there is an art, so to speak, of sufficient tightening, so it stays on, yet is not impossible to remove. I use a dead blow urethane hammer to put the spinners on, with antiseize where needed, then drive the car a bit over a bumpy road, then recheck them, and then safety wire them. Safety wire somes in several gages or strengths, i use strong wire, and wire then spin it to twirl the wire, so that if the spinner were to start to turn and loosen, it is a direct pull on the wire. My wire is basically as close to a 90 degree perpendicular to the end of the spinner wing.

I drilled and slightly chamfered holes in each triwing end, so have three choices to get this angle, and keep the wire away from the air fill valve on the rim.

Thus far, in countless on and off's, i have never had significant difficulty in removing a spinner, nor one that came loose, or seemed too loose when i tapped on it to remove the spinner.

I am packed and prepped for a weekend at Kershaw, aka Carolinas Motorsports Park this weekend. Chris and I are running with the Porsche club. Put on the Vintage 17 inch wheels with the Michelin PS2 tires, and road tested the tires, checked them, then wired them as above. I wire then snug, without any "warning" slack.

I would rather have them snug, than risk loosing a tire because it became loose before i could re-check the "slack". I take the spinners off with a lead hammer.

Just my opinion, and wish Chris and I well this weekend.

all the best....
