• Overall height and rotor height of 56.6 mm, outside diameter of 294 mm

Detailed Product Features and Specifications

The 631-13033L rotor features a vented design that helps maintain optimal braking temperatures by allowing air to flow between the rotor surfaces. The drilled and slotted surface type improves brake pad bite and assists in removing brake dust and gases, which can reduce brake fade during extended use. The directional pattern of the rotor surface is designed to channel water and debris away from the braking surface, enhancing wet weather braking performance.

The rotor’s zinc silver hat finish provides corrosion resistance, extending the service life of the part, while the plain disc finish ensures consistent contact with brake pads. With a bolt hole quantity of five and a bolt hole diameter of 12.9 mm, this rotor fits securely on compatible hubs. The center hole diameter measures 58 mm, matching the hub specifications of the listed Saab and Subaru vehicles.
