The R1 Concepts Geo-Carbon drilled-and-slotted rotor is specified for the rear right position on 1993–2004 Chrysler 300M models. The description calls out a Geo-Carbon rotor with drilled and slotted machining for that side; install this vehicle- and axle-specific replacement and obtain the complementary rear left rotor if replacing both rear rotors.
