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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction offers rotors with enhanced surface features including drilled holes and slots. These design elements help to evacuate gases, dust, and water from the braking surface, improving brake pad contact and reducing fade. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life in various driving conditions.

Technical Specifications and Features

This disc brake rotor is vented to allow air circulation between the rotor faces, which helps dissipate heat generated during braking. The rotor's directional surface pattern combines drilled holes and slots to optimize brake pad cleaning and cooling. With a nominal thickness of 20 mm and a discard thickness of 18.4 mm, the rotor maintains structural integrity and performance throughout its service life. The zinc silver finish on the hat offers rust resistance, while the plain finish on the disc surface ensures consistent braking friction. The rotor features 5 bolt holes with a bolt circle diameter of 114.3 mm, matching the stud/lug hole pattern of the specified vehicles.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Dodge 3000GT and Mitsubishi Stealth
• Improves heat dissipation to reduce brake fade during aggressive driving or towing
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Restores proper rotor thickness to ensure safe braking distances

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 18.4 mm before mounting. Use the correct torque specifications for the 5 lug bolts with a 114.3 mm bolt circle diameter. The directional slotted and drilled surface should be installed following the rotation direction indicated on the rotor to maintain optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on Dodge 3000GT and Mitsubishi Stealth models. The rust-resistant zinc silver coating and vented design contribute to durability and consistent braking performance. Warranty information is not specified for this part number 631-72017L.
