370z DBA 4000 Series Drilled/Slotted Rotor Set, Rear Sport Model Akebono Calipers

4000XS series rotors start with the drilled and slotted design of Street Series XGold rotors and add more cooling slots for a higher level of performance. Rotors are cured with a patented process that reduces iron-weakening metal stress. Recommended for use with passenger cars and SUVs equipped with larger, heavier wheels that will see more aggressive driving. Rotor edges feature 3 paint marks which change color to reflect different levels of metal temperature, and 144 pillars between rotor faces provide faster cooling and greater strength to reduce heat warpage and extend life. Sized to exact OEM dimensions for easy, bolt-on replacement without modification.
