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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve water and gas evacuation during braking. This design helps maintain consistent brake pad contact and reduces brake fade. The zinc silver hat finish adds corrosion resistance, extending rotor life especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor is a solid type with a directional surface, meaning it is designed to rotate in a specific direction to maximize performance. The rotor’s nominal thickness is 10 mm, with a discard thickness of 8.4 mm, indicating when replacement is necessary. The rotor’s surface is finished plain, while the hat features a zinc silver coating that provides rust resistance. It includes five bolt holes and lug holes, each with a diameter of 12.5 mm, arranged on a 114.3 mm bolt circle diameter. The center hole diameter is 69 mm, and the rotor measures 261 mm in outside diameter and 60.2 mm in height.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Mitsubishi Eclipse and Galant
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet conditions due to drilled and slotted design
• Prevents rust and corrosion with zinc silver hat finish and rust-resistant coating
• Restores proper rotor thickness and braking efficiency

Installation Notes and Tips

Ensure the rotor is installed with the directional surface rotating correctly according to vehicle specifications. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter. Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 10 mm. Proper torque specifications should be followed to avoid rotor warping.

Quality Assurance

Dynamite Friction manufactures the 631-72038R rotor to meet OEM standards for fitment and durability. The rust-resistant coating and zinc silver hat finish contribute to long-term reliability. Please consult product documentation or manufacturer resources for warranty details.
