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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is engineered to provide enhanced braking performance through improved heat management. The drilled holes and slots on the rotor surface help reduce brake fade by allowing gases and debris to escape, while the zinc silver hat finish offers corrosion resistance. This product line is suitable for drivers seeking a balance between durability and consistent braking response.

Technical Description and Features

This disc brake rotor features a 330 mm outside diameter and a nominal thickness of 16 mm, with a discard thickness of 14 mm to ensure safe replacement intervals. The rotor’s directional slotted and drilled surface improves water and dust evacuation, which is critical for maintaining braking efficiency under various driving conditions. The zinc silver hat finish combined with a rust-resistant coating helps protect against corrosion, extending the rotor’s service life. The rotor is designed with five bolt holes and a 114.3 mm bolt circle diameter, compatible with specific INFINITI, Mitsubishi, and Nissan models.

Compatible Vehicles and Applications

• INFINITI QX60
• Nissan ARIYA, Murano, Pathfinder, X-Trail
• Mitsubishi Outlander, Outlander PHEV

This rotor is intended for use in disc brake systems on these vehicles, addressing common braking issues such as overheating, brake fade, and uneven pad wear.

Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup
• Uneven brake pad wear due to poor surface design
• Corrosion and rust on rotor surfaces
• Reduced braking performance in wet conditions
• Vibration or noise from warped rotors

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 14 mm before installation. Clean the rotor surface to remove any protective coatings or debris. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt pattern and 114.3 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor warping. This rotor is directional; install with the correct orientation for optimal performance.
