Slotted Rotors can significantly improve brake performance and longevity when used with a matching high friction pad set. Having sold hundreds of thousands of brake kits EBC Brakes feel confident their approach is as perfect as it gets.

We are of the opinion that slotted rotors have been "Over sold" by certain marketplace participants and our findings are that a slotted rotor will only give benefits if used with a pad that compensates for its reduced surface area. 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.


Ultra quiet sport slotted brake rotors are 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.
