Yeah newbie on the Audi side and Im a tad confuse on the disk rotors size.
I'm due for a disk replacement (will get some zimmermans like on my Porsche) and while looking for the models I can see 2 sizes for the front and the rear.
How do you co-relate that to the MY ??

The cars is a A4 Quattro Avant 2003.

Also I'm used to the co-relation of parts from Porsche to VW and Vice-versa, do we have a list of shared parts of the A4 and the VW Passat ?

TIA

288 x 25 front & 245 x 10 rear is the spec from the Model Guide here -> AudiWorld - Model Guide. Unfortunately Audi has a habit of changing specs mid-year as well, so best to ask the dealer and supply your VIN number or measure up whatever you currently have on the car.

depends on the engine as well the 3.0 v6 had bigger front and rear brakes than the 1.8t did.

LOL and I was so used with the non chaging Teutonic mentality of Porsches !!!! Thanks I'll mesure the sizes to be on the safe side

Yes, that's very logical and I would expect also that being a Quattro would use bigger brakes to stop the increased weight of the 4 wheel drive.
