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 reduce brake fade by allowing gases and debris to escape, while the directional surface ensures consistent contact with brake pads. This product line focuses on durability and performance for specific Nissan models, including the 200SX and 300ZX.

Technical Specifications and Features

This disc brake rotor is constructed as a solid rotor with a nominal thickness of 10 mm and a discard thickness of 9 mm, ensuring reliable service life before replacement is necessary. The rotor's outside diameter measures 290 mm, with an overall height of 47 mm. The hat section features a zinc silver finish that provides rust resistance, extending the rotor's durability in various driving conditions. The rotor includes five bolt holes with a bolt circle diameter of 114.3 mm and stud/lug hole diameter of 12.75 mm, matching the factory specifications for Nissan 200SX and 300ZX models. The directional slotted and drilled surface improves heat dissipation and braking response.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on Nissan 200SX and 300ZX
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps maintain consistent braking performance under heavy load or high-speed conditions
• Rust-resistant coating prevents corrosion-related rotor damage
• Directional design supports proper pad contact and braking efficiency

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation direction. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 9 mm. Proper torque specifications should be followed to avoid rotor warping or uneven wear.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM fitment and performance standards for Nissan 200SX and 300ZX vehicles. The rust-resistant zinc silver hat finish adds durability against corrosion. While no specific warranty information is provided, the rotor’s design and materials support reliable braking performance when installed and maintained according to manufacturer guidelines.
