Great, I'll take it in black please, or silver, or green or red. I'd
also be happy with white, blue or yellow. :-)

I'm not so sure that the little mass is an indication of a problem. If
it is, I'd say thatthe mass probably solved it. I'd also predict (or
guess) that if you wre to remove the mass, you probably would not notice
a difference. Its probably one of those things that is barely noticable
unless you have scientific instruments, or a finely calibrated butt (as
opposed to a fine butt which has been calibrated - there is a big
difference, sometimes, _very_ big.)

See above. I suspect that the caliper vibration is not really the
problem that causes UFO rotors to warp. It probably has more to do with
coming out of warp speed too fast.

Try it, and report back please. I'd be glad if you proved me wrong.

Never! Perish the thought.
