I think the biggest bang for your buck is the R1 master. I sourced mine from Yamaha for 150 bucks as compared to 365 for an RCS from Brembo. If its a gen 3 your riding the calipers are good the master and steel line's will make the brakes amazing and you won't have that soft lever any more. I did this mod to all three of my 10's including my gen 4 and what a difference. I would recommend using the Motul RBF 600 or 660 for track day use. I have used the EBC sintered pads before and felt like they lacked power. I've use Vesrah pads and was very happy with performance but they seem to wear out pretty fast. I have been happly with the Galfer 1375 pads but I'm using their rotors also so I don't know how they work on stock rotors.What do you think has been the biggest bang for the buck so far? I have some EBC sintered pads that seem to hold up really well to the heat of the track, and I don't experience any fade. Just never been happy with the soft lever feel.
