The benefits of degassing and promoting flat and smooth pad wear are a clear plus in favor of sport rotors but the trick is to opt for a matched set of brakes and not to just expect a slotted rotor to improve braking on its own. When used with higher friction EBC Redstuff, Greenstuff or Yellowstuff brake pads these rotors will deliver better brakes. The different slot pattern of the EBC USR Series has made this range a popular choice for drivers who desire improved sport braking with minimal air noise from the slots. The finer slot pattern is what makes these sport rotors more silent in operation whilst still offering pad degassing and removing dirt dust water and debris from the braking area. Manufactured using premium disc blanks the narrower multi slot design of the Ultimax sport rotor and the progressive angle at which the slots are machined creates a quiet running sport rotor that still has benefits of removing gas, dirt, water and debris and maintaining parallel pad wear. EBC have always been honest enough to say that the biggest advantage of slotted rotors is the fact that they promote flat and parallel pad wear rather than allowing ridges to develop on pads and rotors which is typical of “drilled only” sport rotors. By preventing these ridges brakes stay more consistent throughout pad and rotor wear life.
