Hi David,
I sure would like to hear some details on the Audi brake adaptation!
thanks,

My only comment to this is why rear discs?  You do only 30% of your braking
with the rear brakes.  A new set of shoes and new pistons will cost a heck of a
lot less than a disc brake system.  My experience with VW / Audi rear discs
is that the ebrake system usually binds after a few years.

If I was going to spend money on a brake system I would install Audi 100/200
dual piston callipers and 276mm vented rotors up front.
