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 on the braking surface. This design improves water and gas evacuation from the rotor surface, which helps maintain consistent braking performance. The zinc silver hat finish adds a layer of rust resistance, extending rotor life in various driving environments. This product line is tailored for drivers seeking reliable, vented rotors with enhanced cooling and surface durability.
Technical Specifications and Features
This disc brake rotor is vented to allow air circulation between the rotor faces, reducing heat and minimizing brake fade during extended use. The directional surface pattern, featuring both drilled holes and slots, aids in removing brake dust and gases, improving pad contact and braking efficiency. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, ensuring safe replacement intervals. The rotor’s hat is coated with a zinc silver finish to resist corrosion, and the rotor includes five bolt holes with a 114.3 mm bolt circle diameter, matching Mazda RX-7 specifications.
Common Applications and Problem Solving
- Replacement for worn or warped rotors on Mazda RX-7 models
- Improves braking performance in wet or dusty conditions
- Reduces brake fade during aggressive or extended driving
- Addresses rotor corrosion issues with rust-resistant coating
- Enhances heat dissipation to prevent premature brake component wear
Installation Notes and Tips
- Ensure rotor thickness is above discard thickness (20 mm) before installation
- Clean mounting surface and hub to prevent rotor runout
- Torque lug nuts to manufacturer specifications for Mazda RX-7
- Inspect brake pads for wear and replace if necessary during rotor installation
