The EBC USR slotted rear rotors for 2003–2004 Subaru Impreza WRX/STI are vented discs machined in the UK to improve cooling and reduce brake fade. The USR slot pattern focuses on quieter operation than many slotted rotors while aiding pad surface condition and heat dispersion. Intended for premium sedans, these rear rotors perform best when paired with a matching high‑friction pad set to maintain stopping consistency under load.
