EBC USR slotted rear rotors for 2005–2010 Chrysler 300 are British-made, precision-machined sport rotors featuring narrow slots designed to reduce air noise while improving brake cooling and pad contact. The USR series emphasizes quieter operation compared with traditional slotted rotors while still helping to lower brake temperatures and maintain pad bedding under sustained use.
