I have read where the slotted the rotors will wear out your pads faster, due to mud and debris getting caught in the slots. Not sure if this is true or not, but it seems logical.i like the highlifter ones theyre slotted and i figured they would be better. Plus i can get them for like 280$ for the whole front setup
Even on Cars its more of a "cool" Factor. most guys in local car club run blank rotors. Not Slotted or Drilled rotors.Other than the "cool" factor of slotted rotors on an atv, whats the point? Unless the brakes are sticking, there isn't any braking performance to be gained. Its not like a car where hot brakes could be an issue if you are constantly on them.
