• Directional, slotted and drilled rotor surface for improved brake cooling
• Vented rotor design to reduce heat buildup
• Rust-resistant zinc silver hat finish for corrosion protection
• 5 bolt holes with a 114.3 mm bolt circle diameter
• Nominal thickness of 26.3 mm and discard thickness of 24.4 mm
• Overall diameter of 294 mm and center hole diameter of 68.7 mm

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 on the braking surface. This design helps to evacuate gases, dust, and water more efficiently than plain rotors, which can improve braking consistency under demanding conditions. The silver zinc coating on the rotor hat provides additional rust resistance, extending the rotor's service life especially in environments prone to corrosion.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat generated during braking. The rotor's directional surface pattern, featuring both drilled holes and slots, is optimized to reduce brake fade and maintain pad bite. The rotor measures 294 mm in outside diameter with a height of 46 mm, fitting precisely on Mitsubishi Eclipse and Galant models requiring a 5-lug bolt pattern with a 114.3 mm bolt circle diameter. The nominal thickness is 26.3 mm, with a discard thickness of 24.4 mm, ensuring safe replacement intervals.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mitsubishi Eclipse and Galant
• Improves brake cooling to reduce fade during heavy braking
• Helps prevent rust and corrosion on rotor hats with zinc silver finish
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Enhances braking performance in wet conditions by channeling water away

Installation Notes and Tips

Ensure the rotor surface is clean and free of oil or debris before installation. Verify the rotor thickness is within specifications before mounting. Use the correct torque settings for the 5-lug bolts to avoid warping. This rotor is directional; install with the correct rotation direction as indicated by the drilled and slotted pattern. No additional hardware is included, so reuse existing mounting components if in good condition.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Mitsubishi Eclipse and Galant vehicles. The rust-resistant coating and vented design contribute to durability and consistent performance. Warranty details are provided by the manufacturer and should be confirmed at the time of purchase.
