The EBC Ultimax rear rotor for 1981–1983 Mazda RX‑7 2.3 (rotary) provides slotted disc performance with reduced air noise by using progressively angled slots. The slots draw in cooling air to help brakes run cooler and clear debris to maintain pad grip and longevity. Dimensioned for direct replacement, these rotors aim to improve thermal control while preserving quiet operation compared to traditional slotted discs.
