It looks like MOST people are installing the friction rings between the hub and the disk, NOT between the wheel and the disc.

To me, it seems like providing the dampening between the wheel and the hub / brake disk assembly makes sense as it isolates it completely from potential vibrations.

Imagine the brake disk is grizzly bear #1 and the hub is grizzly bear #2, both bears are chasing you but bear #1 is 50 feet closer.

Having a barrier between you and bear #2 would be nice, but it wouldn't provide much comfort since bear #1 is still going to get you.

Much better to have that barrier between you and bear #1 and bear #2, not just bear #2.

Friction disc placement between the disc and the hub (stopping only bear #2) would still allow any vibration to be amplified between the disc and the wheel, placing it between the disc and the wheel (blocking bear #1 and bear #2) should remediate any such issue.

I would have used mountain lions, but mountain lion #2 would have just leapt over the barrier.
Every SIB I've seen that shows the Friction Ring installation puts the ring between the hub and rotor plate: https://static.nhtsa.gov/odi/tsbs/20...78996-9999.pdf

I don't think the diagram you linked indicates an area of installation for that wheel disc. If you look at the disc in the diagram, it has a smaller hole that allows the rotor mounting screw to go through the disc. The only reason you would need that hole on the disc is if the disc is meant to be sandwiched between the hub and rotor. Otherwise that screw is flush or slightly recessed into the disc face. If the disc was meant to be used on top of the rotor, it would just have the 5 bolt holes.

I agree that the ring between the wheel and rotor might be more likely to prevent the tick issue, but that isn't something a technician would do when installing the disc at a dealer as part of the service bulletin.

We have seen customers use thin spacers like 3mm between the rotor and wheel to eliminate the noise so a ring between the rotor and wheel might have a similar effect. Your points illustrated by the bears are valid and it could be worth a shot especially if you are DIYing the installation.
