At least 400 degrees, I think.  I'd have to check the tube.

Given that these are rear brakes and the application isn't up close
and personal with the caliper, I'd say its fine.  Its certainly
guaranteed to be higher temp rated than Audi's stuff, and I noticed
no problems during/after a track event at Watkins Glen, which
involves a LOT of heavy braking(as a side note, the UFOs performed
spectacularly(both the rotors and pads were less than a week old.)

The Mobil 1 seemed a much thicker, but to be honest, I think that's a
good thing, since clearly the Audi grease doesn't do much to protect
the pins as is given the damage they usually come out with.

Personally, I'd rather replace the pins since they were slightly bent
in the first place, but I'm not prepared to shell out over $100 for
the carrier to do so.  I am astounded there is no way to get the pins
separately...did they really use different guide pins in all their
different calipers?
