EBC Ultimax slotted front rotors for 1973–1974 Buick Apollo 4.1 applications combine slot geometry with quiet operation to help keep brakes cooler without excessive air noise. Progressively angled slots draw in air to aid cooling and clear debris, preserving pad bite and extending pad life. These vented rotors are sold as OE-style direct-fit replacements.
