So just in case anybody wants to try. The Brembo calipers from the 2017 1000 will fit right onto the 2008 600 with no mods at all. I took one of the calipers off my 2017 1000 and tried it on just to see what I would need to do to make the upgrade. And I was pleasantly surprised that I need to do nothing. I purchased a set of calipers with oem pads in great condition with very low miles on ebay for 500 bucks. I also changed the master cylinder, not sure how it would work if you kept the stock master cylinder.
