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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to optimize brake pad contact and heat dissipation. This design helps reduce brake fade and maintain consistent stopping power. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor is a solid type, measuring 292 mm in outside diameter and 64 mm in overall height. It features a directional surface with both drilled holes and slots, which aid in channeling away gases and debris generated during braking. The rotor’s nominal thickness is 9 mm, with a discard thickness of 8 mm, ensuring clear service limits for safety. The rotor hat is finished in zinc silver to resist corrosion, and the entire rotor includes a rust-resistant coating to further protect against environmental damage. It mounts with 5 bolt holes on a 114.3 mm bolt circle diameter, compatible with the INFINITI Q45’s wheel hub specifications.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on INFINITI Q45
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance under high-stress conditions
• Rust-resistant coating prevents premature rotor corrosion
• Directional drilled and slotted design assists in debris removal and pad cleaning

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 8 mm before installation. Clean the mounting surface and hub to prevent runout. Use proper torque specifications for the 5 lug bolts on the 114.3 mm bolt circle diameter. The directional surface requires correct orientation during installation to maintain optimal braking performance. Avoid contaminating the rotor surface with grease or oil.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit and function. The rust-resistant coating and zinc silver hat finish provide extended durability. While no specific warranty information is provided, adherence to installation and maintenance guidelines will help ensure reliable service life.
