RS4 or RS6 breaks on a A4?

[dappadan786]

hello everyone,

thank you for letting me be part of the ultimate RS forum!

i hope someone can help me here, i want to upgrade the brakes on my A4 1.8T B5.

i would like to use either the S4, RS4 or RS6 calipers + discs/rotors.

i have been told its not a straight bolt on, i will need to replace various parts.

can anyone tell me exactly what parts i would need and what it would involve?

thank you for your help in advance.

Dan
