RS6 rear brake carriers info ??

[B5.5 Swagon]

I have a 03 Passat wagon awd i picked up a set of RS6 rotors awhile back for a good price so now im in the process of buying RS6 front calipers but my question is on the rs6 rear calipers they look very similar to my stock rear calipers so im trying to figure out if its just the carriers that is the differents to compensate for the bigger rotor then the stock rotors on the A6 & Passat. Any help if any body researched this already or have part number to match up to see if the rear calipers are the same it would be greatly appreciated ?

No one out there huh well ive been doing some research and was told i cant use my stock calipers with the rs rotors and a upgraded carrier bracket cause of the rotor offset and stock calipers not being big enough for the wider vented rs rotor witch is 330x22mm. So i wanna find out if i can use the a6 4.2 rear hubs so the rotors and carriers will then fit and ill just have to buy audi rear calipers for vented rotors for it all to bolt up ? Any insite if im on the right path

Can any one tell me the other audi's that come with rear vented rotors so i can check the option of rear calipers i can try and buy to complete my rear brake kit
