I have an 08 with the RCS master, Galfer superbike lines, and ferodo XRAC pads... this thing stops FAST! I rode with 19x20 on the track most of the year but switched to 19x18 the past two track days and the only difference I noticed was a little more rear end stability on initial bite. The rear end did not want to come up in the air as much, but my brake markers were still the same and still moving closer to apex. Just get the RCS and see what you like best. I am pretty sure TENN10 (member here I bought from before) has one for sale.
