So most of us agree, that, through first-hand experience or experience through others, B5 S4 calipers suck. Pad selection blows and they're not all flash performance wise. Sucks for me, I already ended up buying 320x30 disc So we know there's the B7 ATE 2.0T caliper we also know is the same sans carrier (and therefore, disc diameter size) as the B6 S4/B7 S4. We also can identify a large range of other longitudinal Audis these came on esp in 345x30 or 347x30 size. We also know the B7 A4 uses the same size disc as the B5 S4 except those carriers&calipers tend to be much less commonly available... But, what about VWs? What about the 8P S3 or even 8J TT-S? Are they exactly the same caliper/carrier as the B6/B7 S4 setup?
