EBC Ultimax slotted front rotors for 1991–1992 Audi 100 Quattro are precision-machined vented discs with progressively angled slots that pull in cool air for lower operating temperatures. The slotted design clears dust and debris to maintain pad grip and promote pad longevity while minimizing the air noise normally associated with slotted rotors, offering a quieter, cooler-running upgrade for matching high-friction pads.
