B7 S4 Brake Calipers on B6 1.8T

[czm]

Does anybody know if B7 Calipers and carriers will fit on b6 1.8T 2004 Avant?

I have the option of a pair and was wondering if:
1) they will fit
2) What size discs would be needed
3) Is it worth it?

The current discs and pads need replaceing anyways so now woudl be a good time to chance and the calipers I have been offered will not be availble for long.

1) Yes
2) 345mm
3) Definatley.

Great thanks m8

So i need the carriers and calipers along with the 345mm discs and pads. Anything else i to make the swap?

Also would there be any clearance issues with my 17'' OEM Sport alloys?

S4's have 18" wheels to clear the brakes, I doubt 17's would clear them.
