C USR Ultimax Slotted Upgraded Front Discs. 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 simple physics!
