Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the specific braking demands of vehicles like the Toyota MR2, offering a balance of durability and performance without altering the original braking system geometry.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor faces, which helps dissipate heat during braking. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving braking consistency. The rotor has a nominal thickness of 25 mm and a discard thickness of 24 mm, indicating when replacement is necessary to maintain safety. The hat finish is zinc silver with a rust-resistant coating to protect against corrosion. It features 5 bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 62 mm, ensuring proper fitment on the Toyota MR2 hub assembly.

Applications and Problem Solving

• Replacement rotor for worn or warped Toyota MR2 brake rotors
• 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 braking surface for enhanced safety and control

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 24 mm before installation. Clean the rotor surface to remove any protective oils or residues prior to mounting. Verify the 5-lug bolt pattern with a 114.3 mm bolt circle diameter matches the Toyota MR2 hub. Use proper torque specifications for lug nuts to avoid rotor warping. Directional rotors should be installed following the indicated rotation direction for optimal performance.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit and function on Toyota MR2 models. The rust-resistant zinc silver finish helps extend rotor life by preventing corrosion. While specific warranty details are not provided, Dynamite Friction products typically undergo rigorous quality control to ensure durability and reliable braking performance.
