This is true, I neglected to mention that in my original post.
Audi used to use 4x100mm wheels on the FWD 4000s up until some time
in 1986 when they switched to 4x108mm.  If you do the VW rear disc
conversion the brake discs will have 4x100mm...  My 4000 is an early model
(1980) which had the 4x100mm bolt pattern so there is no problem.
If your quantum has 4x108mm then you will need different wheels.
I am not sure the improvements from the rear discs are worth going
that far.
