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 surface features to improve braking efficiency. The drilled and slotted design helps to reduce brake fade by allowing gases and debris to escape, while the vented rotor construction promotes better heat dissipation. The zinc silver hat finish provides corrosion resistance, extending rotor life in various driving conditions.

Technical Specifications and Features

This disc brake rotor is vented, which means it has internal channels to improve airflow and cooling during braking. The rotor's surface is both drilled and slotted, providing a directional pattern that aids in water and dust removal from the braking surface. The nominal thickness of 20 mm ensures durability, while the discard thickness of 18 mm indicates when replacement is necessary to maintain safe braking performance. The rotor features a plain disc finish and a zinc silver hat finish with a rust-resistant coating to protect against corrosion. It includes 4 bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 68 mm, designed specifically for the Nissan 240SX.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Nissan 240SX
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Restores proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18 mm before installation. Clean the hub surface to prevent rotor runout and ensure proper fitment. Use the correct torque specifications for the 4 bolt holes with a 114.3 mm bolt circle diameter. The directional slotted and drilled surface should be installed following the rotation direction indicated on the rotor to maximize performance and longevity.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for the Nissan 240SX. The rust-resistant coating and zinc silver hat finish contribute to extended rotor life. While no specific warranty information is provided, the rotor's design and materials support reliable braking performance under normal operating conditions.
