This vented disc brake rotor features a directional, slotted and drilled surface designed to enhance heat dissipation and maintain consistent stopping power under demanding conditions.

• Nominal thickness: 22 mm with a discard thickness of 20 mm
• Vented rotor design for improved cooling
• Directional slotted and drilled surface for enhanced brake pad bite and debris removal
• Zinc silver hat finish with rust-resistant coating for corrosion protection
• Overall diameter of 250 mm and height of 30 mm
• 6 bolt holes with a bolt circle diameter of 103 mm
• Center hole diameter of 81 mm for precise fitment

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is manufactured with a plain disc finish and a zinc silver hat finish that includes a rust-resistant coating to extend rotor life. The vented rotor design improves airflow, reducing heat buildup during braking, which helps prevent brake fade. The directional surface pattern, combining drilled holes and slots, aids in water and gas evacuation, improving braking efficiency and pad contact. The rotor measures 250 mm in outside diameter and 30 mm in height, with 6 bolt holes spaced on a 103 mm bolt circle diameter, ensuring compatibility with Nissan 720 brake assemblies.

DFC Brake Rotor Product Line Information

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that provide enhanced heat dissipation and surface cleaning through drilled and slotted designs. This product line is tailored for drivers seeking rotors that maintain braking performance under stress by reducing heat and debris buildup, which is critical for vehicles like the Nissan 720 that may experience varied driving conditions.

Applications and Problem Solving

• Compatible with Nissan 720 models requiring vented disc brake rotors
• Addresses brake fade caused by excessive heat during heavy braking
• Helps reduce rotor surface glazing and pad material buildup
• Improves braking performance in wet or debris-prone environments
• Prevents premature rotor corrosion with rust-resistant coating

Installation Notes and Tips

Ensure the rotor is installed with the directional surface pattern oriented correctly to match the vehicle’s rotation direction. Verify that the bolt hole pattern (6 holes on a 103 mm bolt circle) aligns with the Nissan 720 hub assembly. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 20 mm. Proper torque specifications should be followed to avoid rotor warping.
