The EBC Ultimax slotted front rotor for 1982 Porsche 928 4.5L is a vented 282mm disc that uses progressively angled slots to help cool the brake face without the excessive air noise sometimes associated with slotted rotors. Rotors are balanced and runout-tested for smooth operation. This Ultimax design helps clear dust and debris to preserve pad contact and maximize pad life while aiming to keep brake noise restrained compared with aggressive slot patterns.
