About 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 with a corrosion-resistant finish. This product line is designed to provide enhanced braking performance through improved heat dissipation and surface cleaning, which helps maintain consistent brake pad contact. The zinc silver hat finish adds durability against rust, making it suitable for vehicles exposed to varying weather conditions.

Product Details and Specifications

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to reduce heat buildup during braking. The directional slotted and drilled surface improves braking efficiency by channeling away gases, dust, and moisture. The rotor measures 292 mm in outside diameter with an overall height of 41.5 mm, ensuring compatibility with the Saab 9-3 and BLS, as well as select Cadillac models. The rotor features five bolt holes with a 110 mm bolt circle diameter and a center hole diameter of 65.5 mm, matching factory specifications for secure installation.

Applications and Problem Solving

• Replacement for worn or warped rotors on Saab 9-3 and BLS models
• Improves braking performance in wet or dusty conditions through slotted and drilled design
• Reduces brake fade during extended or aggressive braking with vented rotor construction
• Prevents rust and corrosion with zinc silver hat finish and rust-resistant coating
• Maintains proper rotor thickness for safe braking with clear discard thickness guidelines

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 contaminants prior to mounting. Verify bolt hole alignment with the 110 mm bolt circle diameter and confirm compatibility with the vehicle’s lug pattern. Proper torque specifications should be followed to avoid rotor warping or uneven wear.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM standards for fit and function. The rust-resistant coating and zinc silver hat finish contribute to long-term durability. While specific warranty details are not provided, adherence to discard thickness and installation guidelines supports safe and reliable braking performance.
