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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction offers rotors with enhanced surface designs combining drilled holes and slots. This configuration improves water and gas evacuation during braking, reducing fade and maintaining consistent stopping power. The zinc black hat finish provides corrosion resistance, extending rotor life. This product line is tailored for drivers seeking reliable, vented rotors with directional braking surfaces for specific vehicle applications like the Toyota Echo and MR2 Spyder.

Technical Specifications and Features

This disc brake rotor is vented to allow better heat dissipation, which helps prevent brake fade during extended use. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18 mm, indicating when replacement is necessary. The rotor measures 255 mm in outside diameter and 43.2 mm in overall height, fitting precisely on compatible Toyota models. The drilled and slotted surface is directional, designed to channel gases and debris away from the pad surface, improving braking efficiency. The zinc black hat finish adds a layer of rust resistance, protecting the rotor from corrosion over time. The rotor includes 4 bolt holes with a 100 mm bolt circle diameter and a center hole diameter of 55 mm, ensuring proper fitment and secure mounting.

Applications and Problem Solving

• Replacement rotor for worn or warped Toyota Echo and MR2 Spyder brake systems
• Improves heat dissipation to reduce brake fade during aggressive driving or heavy braking
• Helps maintain consistent braking performance in wet or humid conditions due to drilled and slotted design
• Prevents rust and corrosion buildup with zinc black coating
• Restores proper rotor thickness and surface condition for safe braking

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 debris prior to mounting. Verify the 4-bolt hole pattern and 100 mm bolt circle diameter match the vehicle hub. Use proper torque specifications for lug nuts to avoid rotor warping. Directional rotors must be installed with the correct rotation direction as indicated by the surface design to ensure optimal performance.

Quality Assurance

Dynamite Friction manufactures the 633-76072L rotor to meet OEM specifications for Toyota Echo and MR2 Spyder models. The rust-resistant zinc black hat finish and vented design contribute to durability and consistent braking performance. While no specific warranty information is provided, this rotor is produced under quality control standards typical for automotive brake components.
