Details on 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 slots on the braking surface. This design helps to reduce brake fade by allowing gases and debris to escape, while also improving water dispersion in wet conditions. The zinc silver hat finish provides corrosion resistance, extending rotor life. This product line is tailored for drivers seeking reliable braking performance with enhanced heat management.
Technical Specifications and Features
This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively during braking. The rotor’s surface is both drilled and slotted, which supports consistent pad bite and helps maintain braking efficiency. The rotor measures 315 mm in outside diameter and 67.5 mm in height, with a nominal thickness of 20 mm and a discard thickness of 18 mm, ensuring it meets precise fitment and safety standards. The hat section features a zinc silver finish with a rust-resistant coating to protect against corrosion. It includes five bolt holes with a diameter of 12.7 mm and a bolt circle diameter of 100 mm, matching the Subaru Impreza’s specifications.
Applications and Problem Solving
- Replacement rotor for worn or warped Subaru Impreza brake rotors
- Improves heat dissipation to reduce brake fade during aggressive driving
- Helps maintain consistent braking performance in wet or dusty conditions
- Addresses rotor corrosion issues with rust-resistant coating
- Supports safe braking by maintaining proper thickness and structural integrity
Installation Notes and Tips
Ensure the rotor surface is clean and free of any contaminants before installation. Verify that the rotor thickness is above the discard thickness of 18 mm to maintain safety standards. Use proper torque specifications for the five 12.7 mm bolt holes to secure the rotor firmly. This rotor is directional; install it according to the indicated rotation direction to optimize performance and longevity.
Quality Assurance
Dynamite Friction manufactures this rotor to meet OEM specifications for the Subaru Impreza. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion resistance. While no specific warranty information is provided, the rotor’s design and materials align with industry standards for reliable braking components.
