I did look at the Brembo RCS calipers for my Evo some time ago, Darren. If I were to fit them, I decided I'd need a 19RCS (pt. no. 110A26310) for the brake and a 16RCS (pt. no. 110A26350) for the clutch.
The 19RCS works for most twin disc systems, so long as they don't have sliding calipers like the S2R 800. The 16RCS replaces stock 14 or 15mm clutch master cylinders. For reference, the Evo brake and clutch masters are 18mm and 15mm respectively. (I'm not sure about the 796 sizes as it has the coffin masters.)
The brake caliper comes with a microswitch for the brake light, so is "plug and play" but there is no switch on the clutch side so, if your bike has a safety device, you'd have to use a pressure switch instead.
There's some more info. on how to calculate piston ratios in this thread
