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

The DFC Brake Rotor - Drilled and Slotted - Silver line from 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, helping maintain rotor integrity over time. This product line is tailored for drivers seeking rotors that balance performance and durability without vented rotor complexity, as this is a solid rotor design.

Product Specifications and Features

This rotor features a solid disc design with a nominal thickness of 10 mm and a discard thickness of 8 mm, ensuring clear service limits for maintenance. The directional slotted and drilled surface improves water and gas evacuation during braking, which is critical for maintaining consistent stopping power under demanding conditions. The zinc silver hat finish and rust-resistant coating protect against corrosion, extending the rotor's service life. With a 5-bolt hole pattern and 112 mm bolt circle diameter, it fits securely on compatible Audi models.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Audi 200 Quattro and A8 Quattro
• Improves heat dissipation to reduce brake fade during extended braking
• Helps maintain consistent braking performance in wet conditions due to drilled and slotted design
• Prevents rust and corrosion buildup on rotor surface and hat
• Restores proper rotor thickness and braking surface for safe stopping

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify the bolt hole pattern and center hole diameter match your vehicle specifications. Use proper torque settings on lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.

Quality Assurance and Warranty

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit and function. The rust-resistant coating and zinc silver hat finish contribute to long-term durability.
