EBC Ultimax OE-style rear discs for 2003–2010 Audi A8 Quattro 4.2 use progressively angled slots to offer quieter slotted rotor operation while still promoting cooler brake running. The slot geometry helps draw in cool air, clear dust and debris, and maintain pad grip for extended pad life. These vented, OE-dimension discs provide a balance of quiet operation and improved cooling.
