EBC USR slotted front rotors for 2005–2006 Infiniti QX56 (5.6, Bosch fitment) are British-made, precision-machined grey iron rotors in a vented, slotted USR configuration. The USR series aims to reduce heat and maintain pad contact with narrow slots that cut air noise, helping brakes run cooler and stay flat when used with matching high-friction pad sets for demanding use.
