Hi everyone.?
Some years back I had upgraded the front brakes (Calipers and rotors, single piston to two pistons, etc.) on my 1983 URQ. ?Unfortunately, I did not keep notes as what year the upgrades came from. ?I think they were from an 1985/6 Audi 5000 Turbo. ?But I am not sure. Now I need to replace the rotors, but I have no way of knowing what year or model they came from. ?So I took the rotors of the car in the hope of seeing a part number stamped somewhere. ?But I could not see one. ?I do have numbers for the calipers. ?Any help would be greatly appreciated. ?Thanks in advance.

UrQ conversion to 1992-1994 S4/S6/V8 Brakes (G60 type)
19th February 2004, updated 20th September 2004, updated 3rd February 2005.

To do this conversion you will need the following:
Front:
Use S4/S6 G60 Caliper/Bracket Assembly which will fit exactly on the existing UrQ strut mounting holes.
You cannot use either the standard UrQ disc(437-615-301A) or the S4/S6 disc(441-615-301A).
The UrQ disc is very slightly too great a diameter and is not thick enough. The S4/S6 disc is the
correct thickness and diameter but has the wrong ‘top hat’/dish/offset dimension for the UrQ hub.
Use disc from 100/200/5000 Quattro PN 447-615-301A/B. 
There is an equivalent Ate Power disc you might prefer(from Z motors) PN 24.0325-0102.1(525102).
For pads suggest Hawk HPS compound pad number HB270.

Rear:
Use the complete S4/S6/V8 setup, calipers and discs. You will also need to change to the pair of handbrake cables used on the 1984 and later 4000 Quattro, and if pre 85 car, a new handbrake yoke to accommodate the ‘hook type’ cable ends.
Disc PN 857-615-601.
Suggested Hawk HPS Pad HB271.
Handbrake Cables Left 857-609-721D, Right 857-609-721E.
Handbrake Cable Yoke 437-711-097.

Suggest you discard the S4 intermediate hydraulic hose support bracket on the front caliper(it can interfere with the strut), and replace with a suitable SS protected Teflon line directly from the caliper to the body connection. You could use the standard S4 hydraulic hose at the rear but it is better to replace it with SS protected Teflon.
