rs4(b5) rear brakes to a41.8tq

[snowfun4q]

Is it possible to use rs4 rear discs and callipers/carriers in a a4 1.8tq b6?If so ,do they fit straight on?

[snowfun4q]

Has anyone done this mod to b5 or b6?

suggest not tried, too large a disc(??) and the various offsets are probably wrong.
Now B5 S4 rear will work, full details are on Audiworld
