The EBC USR slotted rear rotors for 2011–2012 Chevrolet Impala 3.5 combine precision British machining with narrow angled slots to reduce air noise while improving brake cooling. The slot pattern pulls cool air to lower operating temperature, helps clear dust and debris to preserve pad bite, and reduces fade at speed. These solid 270mm discs are intended as a direct OE-style replacement for the rear axle.
