This vented disc brake rotor features a directional, slotted, and drilled surface designed to enhance heat dissipation and maintain consistent stopping power.

• Compatible with Mitsubishi Eclipse and Galant vehicles
• Directional, slotted and drilled rotor surface for improved cooling
• Vented rotor design to reduce heat buildup
• Rust-resistant zinc silver hat finish for durability
• 5 bolt holes with 114.3 mm bolt circle diameter
• Nominal thickness of 20 mm with discard thickness at 18.4 mm
• Overall diameter of 284 mm and height of 60.4 mm

Detailed Product Features and Specifications

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented rotor design that helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during extended use. The rotor surface is both drilled and slotted, which aids in channeling away brake dust, gases, and water, improving braking consistency in various conditions. The directional surface type ensures optimal performance when installed in the correct orientation.

The rotor features a plain disc finish combined with a zinc silver coating on the hat area, providing corrosion resistance to extend the rotor's service life. With a nominal thickness of 20 mm and a discard thickness of 18.4 mm, this rotor meets precise wear limits for safe operation. The 5-lug bolt pattern with a 114.3 mm bolt circle diameter and 12.6 mm stud hole diameter matches the factory specifications for Mitsubishi Eclipse and Galant models.

About the DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors that balance performance and durability. These rotors are designed with vented construction and directional drilled and slotted surfaces to improve heat management and braking response. The silver zinc coating on the hat area enhances corrosion resistance, making them suitable for daily driving and moderate performance applications on compatible Mitsubishi vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mitsubishi Eclipse and Galant
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps prevent brake judder caused by uneven rotor surfaces
• Reduces rust buildup on rotor hats for longer service life
• Maintains consistent braking performance in wet or dusty conditions

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated on the rotor. Verify that the rotor thickness is within the nominal and discard limits before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Use proper torque specifications for the 5-lug bolt pattern to avoid warping or uneven wear.
