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 enhance brake pad bite and heat dissipation. This product line is designed to reduce brake fade and maintain consistent braking performance under demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Specifications and Features

This rotor features a solid disc design with a directional surface type that includes both drilled holes and slots. The drilled holes help vent gases and reduce heat buildup, while the slots assist in removing brake dust and water from the rotor surface. The rotor's nominal thickness is 10 mm, with a discard thickness of 8.3 mm, ensuring safe replacement intervals. The zinc silver hat finish offers rust resistance, protecting the rotor's core components. With 5 bolt holes arranged on a 112 mm bolt circle diameter and a center hole diameter of 67 mm, this rotor fits securely on compatible INFINITI and Mercedes-Benz models.

Applications and Problem Solving

• Improves braking performance on INFINITI QX30 and Mercedes-Benz B250e, CLA250, GLA200, and GLA250 models
• Reduces brake fade during extended or aggressive braking
• Helps prevent rotor warping caused by excessive heat
• Minimizes rust and corrosion on rotor hats for longer durability
• Enhances brake pad cleaning and gas venting for consistent stopping power

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the bolt hole pattern matches the vehicle hub (5 bolts on a 112 mm circle). Use proper torque specifications for lug nuts to avoid rotor distortion. Since this rotor is directional, confirm the correct orientation during installation to maintain optimal braking performance. Check rotor thickness regularly and replace when thickness reaches the discard limit of 8.3 mm.

Quality Assurance

Dynamite Friction manufactures the 631-63107R rotor to meet or exceed OEM standards for fit, form, and function. The rust-resistant coating and precision machining contribute to consistent performance and durability. While specific warranty details are not provided, this rotor is designed for reliable service life on compatible INFINITI and Mercedes-Benz vehicles.
