The EBC Ultimax rear rotor is an OE-style slotted disc engineered to reduce air noise while improving cooling for 2003–2004 Pontiac GTO 5.7. The progressively angled slots pull air through the rotor to help control temperature and clear dust, supporting consistent pad contact. At 286mm diameter and vented construction, this rotor balances quieter operation with improved cooling and pad longevity for drivers who want an effective, sensible upgrade over plain replacement discs.
