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 both drilled holes and slots to aid in gas and dust evacuation during braking. This combination helps reduce brake fade and improves rotor cooling, which is critical for maintaining braking efficiency in Mini Cooper vehicles. The silver zinc coating on the rotor hat provides additional corrosion resistance, extending the rotor's service life.

Technical Specifications and Features

This disc brake rotor is a solid type with a 259 mm outside diameter and a nominal thickness of 10 mm, ensuring compatibility with Mini Cooper brake systems. The rotor’s surface is both drilled and slotted, which enhances heat dissipation and helps maintain clean pad contact. The rotor features a zinc silver finish on the hat for rust resistance, and the entire rotor is coated to protect against corrosion. The bolt hole diameter is 16.2 mm with four bolt holes arranged on a 100 mm bolt circle diameter, matching Mini Cooper mounting requirements precisely.

Applications and Problem Solving

• Replacement rotor for worn or warped Mini Cooper brake rotors
• Improves heat dissipation to reduce brake fade during extended braking
• Helps prevent brake pad glazing by evacuating dust and gases
• Corrosion-resistant coating extends rotor lifespan in harsh environments
• Maintains consistent braking performance under normal and spirited driving conditions

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective oils before installation. Verify that the rotor thickness is within the nominal 10 mm specification and above the discard thickness of 8.4 mm. Use the correct torque specifications for the four 16.2 mm bolt holes on the 100 mm bolt circle diameter to secure the rotor properly. This rotor is directional; install it according to the indicated rotation direction to optimize performance.

Quality Assurance

Dynamite Friction manufactures the 631-32003L rotor to meet OEM standards for fit and function on Mini Cooper vehicles. The rust-resistant zinc silver coating and corrosion protection ensure durability. While no specific warranty information is provided, the rotor is designed to maintain consistent braking performance and structural integrity under normal operating conditions.
