Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on rotors designed to improve braking efficiency through enhanced heat management. The drilled and slotted surface pattern helps reduce brake fade by allowing gases and debris to escape, while the vented rotor design promotes airflow to maintain optimal operating temperatures. This rotor line is suited for drivers seeking a balance between performance and durability on their Nissan Maxima or INFINITI I30.

Technical Description and Features

This disc brake rotor features a plain disc finish combined with a zinc silver hat finish that provides rust resistance, helping to maintain structural integrity over time. The rotor’s 280 mm outside diameter and 49.2 mm height are engineered to match factory specifications for compatible vehicles. The directional slotted and drilled surface improves water and dust dispersion, enhancing braking response in various conditions. With a 5-bolt hole pattern and a bolt circle diameter of 114.3 mm, this rotor fits securely on the specified Nissan and INFINITI models. The vented design allows air to flow between the rotor faces, reducing heat buildup during braking.

Compatible Vehicles and Common Applications

• Replacement rotor for Nissan Maxima models requiring a 280 mm vented disc rotor
• Suitable for INFINITI I30 vehicles needing a drilled and slotted brake rotor
• Addresses issues such as brake fade during heavy use or high temperatures
• Helps reduce rotor warping caused by excessive heat
• Improves braking performance in wet or dusty driving conditions

Installation Notes and Tips

When installing the Dynamite Friction 631-67048L rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the bolt hole pattern and center hole diameter match the vehicle hub for proper fitment. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Follow manufacturer torque specifications for lug nuts and bolts to avoid rotor damage or uneven wear.

Quality Assurance and Warranty

Dynamite Friction rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The zinc silver hat finish and rust resistant coating contribute to the rotor’s durability and corrosion resistance.
