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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with enhanced cooling and debris removal capabilities. The drilled holes and slots improve brake pad bite and reduce brake fade by allowing gases and heat to escape more efficiently. The zinc silver coating on the rotor hat provides corrosion resistance, extending rotor life in various driving environments.

Technical Description and Specifications

This disc brake rotor is vented to improve airflow and heat dissipation during braking, which helps maintain consistent brake performance. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18 mm, indicating when replacement is necessary to ensure safety. The rotor features a directional surface pattern combining drilled holes and slots, which aids in water and dust evacuation while enhancing pad contact. The rotor’s overall diameter measures 252 mm, with a height of 49.2 mm and a center hole diameter of 68 mm. It includes 4 bolt holes with a bolt circle diameter of 114.3 mm, matching the Nissan 240SX specifications.

Applications and Problem Solving

• Compatible with Nissan 240SX models requiring vented, drilled, and slotted rotors
• Helps reduce brake fade during aggressive or repeated braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking performance in wet or dusty conditions
• Provides corrosion resistance to extend rotor lifespan

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18 mm before installation. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify bolt hole alignment with the Nissan 240SX hub using the 114.3 mm bolt circle diameter and 4 bolt holes. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the rotation arrow pointing in the correct direction of wheel rotation.

Quality Assurance

Dynamite Friction manufactures the 631-67027R rotor to meet OEM standards for fitment and performance on Nissan 240SX vehicles. The rust-resistant zinc silver coating on the rotor hat helps prevent corrosion, contributing to durability. While no specific warranty information is provided, the rotor is designed to maintain structural integrity and braking efficiency within the specified thickness limits.
