I have had no issues with fitment. These brakes are perfectly machined. Coupled with EBC HH pads. My bike now stops on a dime. They are not grabby, it's very linear and smooth yet it slows you down very rapidly. I haven't had the chance to test them on a track. But so far they are amazing on the street.
My 07 600rr needed a new set of rotors and pads, I went this route to get better performance and looks. well I got more than I could have asked, on the bike these rotors are eye candy. Performance does not fall short though, You have to break them in properly (accelerate fast and hard hard brake over and over again), the bite is amazing, and stopping much more confident. Can't wait for more track days! Late braking and tucking here we come!
