Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of vehicles like the Subaru Impreza that require durable, vented rotors with directional braking surfaces for enhanced control and safety.

Technical Description and Specifications

This disc brake rotor is vented to allow air circulation between the rotor faces, which helps dissipate heat generated during braking. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving braking consistency. The rotor has a nominal thickness of 24 mm and should be replaced once it reaches the discard thickness of 22 mm to maintain safe braking performance. The rotor’s outside diameter measures 277 mm, with a height of 48.2 mm, and it features a 5-bolt pattern with 13 mm bolt hole diameter and a 100 mm bolt circle diameter. The zinc silver hat finish and rust-resistant coating help protect against corrosion, which is important for longevity in various driving environments.

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 directional braking surface for enhanced pedal feel and control

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 22 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify the 5-lug bolt pattern and 100 mm bolt circle diameter match the vehicle specifications. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet industry standards for durability and performance. The rust-resistant coating and zinc silver hat finish contribute to extended rotor life. While specific warranty details are not provided, Dynamite Friction products typically adhere to quality control processes to ensure reliable fitment and function for Subaru Impreza vehicles using part number 631-13039R.
