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 to enhance brake pad bite and reduce heat buildup. This product line is designed to maintain braking performance under demanding conditions by improving ventilation and minimizing brake fade. The zinc silver hat finish and rust-resistant coating extend rotor life by protecting against corrosion, making it suitable for vehicles like the Nissan Armada and INFINITI QX56 and QX80.

Product Features and Specifications

This disc brake rotor features a vented design that allows air to flow through the rotor, helping to dissipate heat more effectively during braking. The drilled and slotted surface improves water and debris evacuation, which can enhance braking response in wet or dusty conditions. The rotor’s nominal thickness of 20 mm ensures durability, while the discard thickness of 18 mm indicates when replacement is necessary to maintain safety.

Compatible Vehicles and Applications

• Compatible with INFINITI Armada, QX56, and QX80 models
• Designed for Nissan Armada, QX56, and QX80 vehicles requiring a 6-bolt vented rotor
• Ideal for addressing brake fade and overheating issues in heavy-duty SUVs
• Suitable for replacement when rotor thickness approaches discard limits
• Helps maintain consistent braking performance under towing or heavy load conditions

Installation Notes and Tips

• Ensure rotor thickness is above the discard thickness of 18 mm before installation
• Verify bolt hole pattern matches vehicle specifications (6 bolts, 139.7 mm bolt circle diameter)
• Clean rotor surface and hub mounting area to prevent uneven wear or vibration
• Use proper torque specifications for lug nuts to avoid rotor warping
• Check compatibility with existing brake pads and calipers on INFINITI and Nissan models
