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 evacuate gases, dust, and water from the rotor surface, reducing brake fade and improving pad bite. The zinc silver hat finish provides corrosion resistance, extending rotor life in various driving environments.
Technical Specifications and Features
This disc brake rotor is vented to allow better airflow and heat dissipation, which is critical for maintaining braking performance during repeated stops. The rotor’s nominal thickness is 23 mm, with a discard thickness of 21 mm, ensuring a clear service limit for safety. The rotor measures 315 mm in outside diameter and 48 mm in overall height, fitting precisely on the Cadillac ATS hub with a 70.7 mm center hole diameter. The 5 bolt holes, each 14 mm in diameter, are arranged on a 115 mm bolt circle diameter, matching the vehicle’s lug pattern.
Applications and Problem Solving
- Replacement for worn or warped rotors on Cadillac ATS models
- Improves heat dissipation to reduce brake fade during aggressive driving
- Slotted and drilled surface helps maintain consistent braking in wet conditions
- Rust-resistant coating prevents corrosion and extends rotor lifespan
- Directional design optimizes braking performance and pad contact
Installation Notes and Tips
Ensure the rotor thickness is above the discard thickness of 21 mm before installation. Clean the rotor surface to remove any protective coating or residue before mounting. Verify bolt hole alignment with the 5-lug, 115 mm bolt circle pattern on the Cadillac ATS hub. Proper torque specifications should be followed to avoid rotor warping. It is recommended to replace brake pads when installing new rotors for optimal performance.
Quality Assurance
Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit and function. The rust-resistant zinc silver hat finish provides added durability against corrosion. While no specific warranty information is provided, the rotor’s design and materials support reliable braking performance consistent with professional automotive standards.
