    After re-tightening the thru axle to a high degree, the rotor seems to be holding in the correct position.

    A related question: the rotor does seem to have a small amount of wobble between the sides of the caliper. When properly aligned, it is not enough to touch either brake pad, but it does get close. There is movement of perhaps 0.5mm. Is this within the normal range of rotor tolerances?

    take the bike out for a ride and report back.

    .5mm wobbling sounds "ok", but considering your issue, maybe you want a straighter rotor

    You're right, I think I might buy another rotor anyway. Unfortunately I've just come down with a bad cold so it will be a few days before I can take the bike out again.

    You may be able to just swap front and rear rotors for experiment's sake, a lot of road bike rotors are the same diameter on both ends as opposed to mtn bikes. Apologies if you've done that already.

    Why not try straightening it out?

    I don't think your going to bend it closer than .5mm, that is pretty small.
    Unless you are really really good mech!

    .5 mm is a very, very small amount of run out. I don't think you can get any better than that. You probably have .5 mm of run out in the hub brake mounting surface.
    You can't fix stupid.

    The 0.5 mm value was reported by the OP. Was it measured or visual? If it was done visually, I suspect the runout is more than 1/2 mm.

    It was visual, so probably completely inaccurate.

    I've just ordered some SRAM Centerline rotors to try instead of the DA ones, so we will see if these are any straighter.

    DAs are excellent, have them on two of my bikes. Any bit of truing can be done by eye and feel after watching a few videos, just have a good truing fork on hand.

    Thanks, but the quickest way for me to turn these rotors into something with the shape of a small metal frisbee would be to go near them with a truing fork.

    Kudos for knowing your limits and admitting it. Hope it turns out well for you with the new rotors
