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 favour 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.
