Brake Rotors
Brake rotors work with brake pads to bring your vehicle to a controlled stop. Upgrading from worn or stock rotors to a performance or OE-quality replacement improves braking consistency, reduces fade, and restores the original factory feel. Popular ProductsPopular brake rotor choices include EBC Brakes USR slotted rotors, Brembo OE-replacement rotors, StopTech Sport cross-drilled and slotted rotors, and Centric Premium rotors for OE-quality service replacement. What is the difference between slotted, drilled, and blank rotors?Blank rotors are standard OE-style with no machining, suitable for daily drivers. Slotted rotors have channels cut into the face for debris evacuation and improved high-heat performance. Cross-drilled and slotted rotors combine both features but may crack under extreme track use. How do I know when brake rotors need replacement?Replace rotors when rotor thickness falls below the minimum spec stamped on the rotor hat, when lateral runout exceeds 0.003 inches, or...
