Right you are, especially at the speed potential of these cars--stock or
chipped.

actually, the rotors are 10.9" and are the "updated" to the '92 S4 rotors
(and hub/strut and ... and ...).  They are essentially the same as the '90
and earlier dual caliper setup, but someone recently informed me that the
"update" conversion requires a few less parts to change over than does the
"backdate" conversion.  don't have all the details on this yet, but perhaps
sometime i'll look through the fiche.
