The EBC Ultimax slotted rear rotor set for 1986–1991 Porsche 928 5.0 provides OE-style vented rotors with progressively angled slots to improve cooling and reduce dust and debris at the pad face. The slot pattern pulls in cool air for more consistent braking temperatures while offering quieter operation than conventional slotted rotors, helping maintain pad grip and extend pad life without excessive air noise.
