• Disc type: Vented disc brake rotor with drilled and slotted surface
• Finish: Plain disc surface with zinc silver hat finish and rust-resistant coating
• Dimensions: 277 mm outside diameter, 56.7 mm overall height
• Thickness: Nominal 24 mm, discard thickness 22 mm
• Mounting: 5 bolt holes with 12.8 mm diameter, 100 mm bolt circle diameter
• Directional brake surface optimized for heat and debris management

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is designed with a vented rotor type to improve airflow and reduce heat buildup during braking. The drilled and slotted surface enhances water and gas evacuation, which helps maintain consistent brake pad contact and reduces brake fade. The rotor's plain disc finish combined with a zinc silver hat finish provides corrosion resistance, extending the rotor's service life. With a nominal thickness of 24 mm and a discard thickness of 22 mm, this rotor meets precise wear limits for safe operation.

The rotor features a directional surface pattern, which is specifically engineered to optimize braking performance by channeling heat and debris away from the contact surface. The 5-bolt hole configuration with a 100 mm bolt circle diameter ensures compatibility with the specified Saab and Subaru models, including the Subaru Forester, Impreza, Legacy, and Outback.

Compatible Vehicles and Applications

• Saab 9-2X
• Subaru BRZ
• Subaru Forester
• Subaru Impreza
• Subaru Legacy
• Subaru Outback

This rotor is suitable for drivers seeking to replace worn or damaged rotors on these specific models, ensuring proper fitment and braking performance.

Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup
• Uneven brake pad wear due to poor rotor surface design
• Corrosion and rust on rotor surfaces
• Reduced braking efficiency from warped or damaged rotors
• Brake noise and vibration from worn or glazed rotors

Installation Notes and Tips

When installing the Dynamite Friction 631-13009L rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the directional surface is oriented correctly according to the vehicle’s rotation direction. Use proper torque specifications for the 5 lug bolts to avoid warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
