EBC Ultimax slotted front rotors for 1977–1981 Porsche 928 4.5 provide the cooling and debris-clearing benefits of slotted rotors while limiting the air noise usually associated with slots. Progressively angled slots pull in cool air to aid brake performance and help maintain pad grip and longevity. These vented OE-style discs match FMSI D251 fitment and original front rotor dimensions for direct replacement.
