Can you feel the difference between the OEM brakeline and the SS brakeline when street riding? Since the SM already has 310mm rotor whats the big difference for the extra 10mm? Any significant? I'm not racing this bike ever...just racing my self on back roads thats about it. Wheelingcycle has a Braking 310mm, and then the 320mm I'm guessing the 320mm is for racing aps.? or should I dish out the extra bucks and get the 320mm?
