Hi,

I have 1991 Audi 90Q 20V and need to change the pads and the rotors. Local pick-n-pull has 1993 audi 90Q V6, so, I went and picked up the G60 calipers and caliper brackets there. What rotors do I need to run to make this work? Should I order rotors for the 1993 Audi 90Q or 276mm rotors for the 1991 90Q. And is that all I need?

Thanks

Klim

You need to get the rotors for the B3 20v that had them factory. And you will probably need to use a washer to space out the caliper. Thats what i did.

If you want to run Girling 60 calipers on a B3 90Q 20V, that originally came with Girling 54s, you need this 276X25 rotor.

893 615 301

This rotor only fits B3 90Q 20vs. It does not fit B3 90Q 10Vs, CQs, B4s, B3/4 FWDs if all the cars have the stock hub carrier.
