All EBC rotors including new super silent Ultimax USR Slotted Rotors are British made and are precision machined in the UK. Rotors are made from high quality grey iron to exacting standards and undergo extensive testing and rigorousquality control. Slotted rotors can significantly improve brake performance and longevity when used with a matching high friction brake pad set. Having sold hundreds of thousands of brake kits EBC Brakes feel confident their approach is as perfect as it gets.
EBC are of the opinion that slotted rotors have been "Over sold" by certain marketplace participants and their findings are that a slotted rotor will only give benefits if used with a pad that compensates for its reduced surface area.
EBC recommend the use of a premium pad such as Redstuff brake pads or Yellowstuff brake padsto complement your new USR slotted rotors which will provide the optimum balance of life and performance.
