Front brake pads and discs

[Sir WIll]

Front brakes have been a little poor of late and also getting a squeal from the front pads.

Had a look today and I have a nice 3 to 4mm lip on the outside edge of the front discs so its time for new discs and pads I think.

The problem I have is there seems to be a difference on what various web sites are telling me to get 280mm, 323mm 328mm etc discs.

All I would like is a good like for like replacement, no need for upgrades.

Could anyone confirm the actual parts for discs and pads on a 2002 D2 FL 3.7 Quattro Sport?
