Detailed Product Features and Specifications

This StopTech rotor is a vented type, which helps reduce brake fade by allowing better airflow through the rotor vanes. The straight vane style supports efficient heat dissipation during heavy braking. The rotor’s surface is cross-drilled and slotted, which aids in removing brake dust, gases, and water from the pad surface, improving brake bite and consistency. The coated hat finish protects against rust and corrosion, extending the rotor’s service life. With six mounting bolt holes and a bolt thread pitch of 1.250, this rotor mounts securely behind the hub, ensuring proper alignment and fitment.
