Greetings from the US,
I am looking for the OEM part numbers for both rear b5 RS4 calipers.
Also,
What is the most common and cost-effective rear brake upgrade?
Do B7 RS4 rear calipers and rotors fit the b5?
Thanks for the information!
James
RS4 Rear brake OEM caliper part number and rear brake upgrade options?
Re: RS4 Rear brake OEM caliper part number and rear brake upgrade options?
Yes they do fit . No brake performance gain .Only aesthetics. Eurocarparts will do an exchange basis for your old ones for iirc TRW ones .

Do the B7 RS4 calipers fit onto the b5rs4 without any other provision? Bolt on?
Must I pair them with b7 RS4 rotors? I read something about needing to drill into the uprights?

Yes you will need to use the B7 rotors with the B7 calipers / carriers and splash guards.. You will have to enlarge the hole in the upright as the bolt is a larger diameter on the B7 . To get to the lower hole you have three options a) remove the hub , b) grind a scallop into it so you can drill the hole straight , c) remove the upright completely and drill from the rear .
People have used a nut and a bolt with a ' grippy ' washer to some effect.
Like I said in the other thread not any benefit I and others have noticed apart from aesthetics.
