    Are they used or new? If used, over time the rivets can get some play in them. In the past I have seen where people with those rotors use an appropriately sized punch to flare the rivets out slightly which takes up the slack.

    Normally the rear rotor suffers with this first time I have heard of the front ones doing it I had to tighten the rivets in my rear one no problem since.

    That has only been with the stock rear rotor.

    The picture shows a Galfer's Wave rotor. Who knows if they're supposed to have some movement, or not?

    My stock rear rotor has some fore to aft movement. Been that way for a year or so, and it hasn't been a problem at all. A friend has an 06, and his has had that movement for many years. He still rides it without problem.

    My 2006 has a loose rotor in the rear. It works fine some of the time, and some of the time is makes the most terrible squealing sound possible. Since it is intermittent, I haven't changed the rotor or tightened the rivets. I will tighten them when I remove the rear tire next time.

    A friend with a 2007 had a loose rotor and it squealed all the time, so he replaced it. I have another friend with a 2007 with a loose rotor and it doesn't squeal, so he is not doing anything about it.

    These are floating discs that allow the rotor to expand when they get hot.

    There's lots of posts with the rear rotor and easy fix is compressing ball bearings. I haven't seen this described on the fronts before

    Arashi’s are actually a decent rotor. If you’d spend a couple minutes researching them you will find there are some write-ups where they have been tested by end (3rd party) users, with some of that being track usage, and they have received favorable reviews.
