EBC Ultimax premium rear rotors for 2003–2004 Subaru Impreza WRX/STI employ angled slots to limit the air noise normally associated with slotted discs while still aiding brake cooling. This design helps preserve pad contact and reduce heat-related pad fade, delivering stable braking characteristics and extended pad life. These vented rear rotors aim to offer quieter operation with the thermal benefits of slotted designs.
