• Outside diameter of 348 mm and discard thickness of 34.4 mm

Detailed Product Features and Specifications

This disc brake rotor features a vented design that improves airflow to reduce heat buildup during braking, which helps maintain consistent stopping power. The surface is both drilled and slotted, allowing for better water and debris evacuation while reducing brake fade. The directional pattern of the rotor surface is engineered to optimize braking efficiency and pad contact. The rotor’s plain disc finish is complemented by a Geospec silver grey hat finish, providing a durable and corrosion-resistant surface. Additionally, the rotor is coated with a rust resistant layer to extend its service life, especially in environments prone to moisture and road salt. With an outside diameter of 348 mm and a discard thickness of 34.4 mm, this rotor meets OEM specifications for fit and function.
