About the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to optimize braking efficiency. This product line is designed to reduce brake fade by improving airflow and allowing gases and debris to escape from the rotor surface. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life in various driving environments.

Product Details and Specifications

This disc brake rotor is vented, which means it has internal channels to facilitate airflow and heat dissipation during braking. The rotor’s directional surface features both drilled holes and slots, which help maintain clean pad contact and reduce the risk of glazing. The rotor measures 230 mm in outside diameter and 52 mm in height, with a nominal thickness of 18 mm and a discard thickness of 15.5 mm, ensuring it meets Subaru Standard specifications. The zinc silver finish on the hat offers rust resistance, while the plain finish on the disc surface maintains consistent friction characteristics.

Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Helps maintain consistent braking performance in wet or dusty conditions
• Minimizes brake pad glazing and debris buildup
• Provides corrosion resistance to extend rotor lifespan

Installation Notes and Tips

Ensure the rotor is compatible with your Subaru Standard model before installation. Verify that the bolt hole pattern (4 holes, 10x1.25 mm diameter, 90 mm bolt circle) matches your vehicle’s hub. Clean the rotor surface of any protective coatings or oils before mounting to ensure optimal pad contact. Follow manufacturer torque specifications for lug nuts and inspect brake pads for wear during installation.

Quality Assurance

Dynamite Friction manufactures the 631-13031R rotor to meet OEM standards for fit and function. The rust-resistant zinc silver coating helps protect against corrosion, contributing to long-term durability. While no specific warranty information is provided, this rotor is designed to maintain consistent braking performance when installed and maintained according to vehicle manufacturer guidelines.
