The EBC Ultimax slotted rear rotor set for 2004–2005 Buick Century 3.1 gives OE-style solid discs with progressively angled slots that pull cool air through the pad face. Those slots clear dust and debris to help maintain pad grip and longevity while reducing the air noise typically associated with slotted rotors. This rear disc set measures 278mm diameter, 11mm thick with a 70.6mm center hole and five-bolt pattern.
