[Biturbos4] Brake upgrade / EBC Greenstuff

What I was suggesting was that I seem to have more of a problem with the EBC
pads than with OE.  Suggests to me that maybe the rust on the rotors thing
is somehow related to or influenced by the pad compound, too.

As for feedback on the EBC pads, I forgot to mention that they seem more
unpredicable when cold, especially grabby at low speed, like in traffic.
Could be true of all pads designed to operate under harder driving
conditions.  I remember my old GT-350 actually had a sticker on the dash
warning about problems with cold brakes.  At the time I thought it was
extremely cool!

As you (Keman) are an Audi tech guy, why do you think Audi has so much
trouble with the rusting brake rotor thing?  Doesn't seem to be an
industry-wide problem.  Isn't this a big customer satisfaction issue?
