The 1983 Ur-q rear calipers were basically modified rear 5000 turbo FDW
calipers (very heavy and fubared design with both e-brake brackets for 5kt
and Ur-q).
In 1984 Ur-q changed to a 4000 quattro caliper which had a larger piston and
was designed for the 4000 quattro/Ur-q.
This would be a worth while upgrade.

Your '85 should have the newer 4000 quattro calipers.  Compare and you will
see for yourself.
