The R1 Concepts slotted brake rotor for 2006–2009 Pontiac Montana (front left) is a black-finished replacement rotor intended for the left front braking position across those years. It identifies axle and side to make ordering the correct front rotor straightforward during service. The slotted face and black finish match common aftermarket replacement-rotor styling.
