The EBC Ultimax slotted rear rotors for 2009+ BMW Z4 (E89) offer a vented OE-style disc designed to aid pad cleaning and heat dissipation while minimizing the air noise typical of slotted designs. Progressively angled slots draw cool air and help clear debris to maintain pad grip and pad life. These rear rotors match OE dimensions for direct replacement and consistent braking performance.
