Thinking about a possible brake upgrade, seeing as it sounds like the multi-piston S8 front calipers will work on a B6 (sexier than a B6 S4 upgrade, and cheaper than a BBK).

A couple of questions arise, howver:
Will the 4 piston S8's work on a B6 A4?
What size rotors would be required ? 320mm?
Any idea which caliper brackets would be needed?

Anything else I'm missing?

Thanks,

Nick
