Damper ring (anyone with an S4/S6 fiche?)

["Rob Winchell" <rbw@avs.com>]

In the Bentley for my 91 200Q, it says that the damper ring that goes on the
top of the front coil spring comes in different thickness, so you can adjust
the  ride height of the car. My parts fiche for the car has only one ring,
with a thickness of 23mm. If someone has a fiche for an S4/S6, could you
look and see what thickness the ring is?

Thanks,
