DFC Brake Rotor - Drilled and Slotted - Black Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that feature a combination of drilled holes and slots on the braking surface. This design improves water and gas evacuation during braking, which helps maintain consistent stopping power under demanding conditions. The black zinc coating on the rotor hat provides additional protection against rust, extending the rotor's service life. This product line is tailored for drivers seeking reliable performance and durability in their BMW brake systems.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to reduce heat buildup during braking. The rotor's directional surface is both drilled and slotted, which aids in removing brake dust and gases, improving pad contact and braking efficiency. The rotor measures 348 mm in outside diameter with a height of 73.3 mm, and it features a nominal thickness of 30 mm, with a discard thickness of 28.4 mm to indicate when replacement is necessary. The rotor includes five bolt holes with a diameter of 14.6 mm arranged on a 120 mm bolt circle diameter, ensuring proper fitment on compatible BMW models.

Applications and Problem Solving

• Replaces worn or warped rotors on BMW 325i, 335d, 335i, 335is, 335i xDrive, 335xi, and X1
• Addresses brake fade caused by excessive heat during aggressive driving or towing
• Improves braking performance in wet conditions by evacuating water from the rotor surface
• Reduces brake dust buildup for cleaner braking components
• Prevents rust and corrosion on the rotor hat for longer service life

Installation Notes and Tips

Ensure the rotor is compatible with your specific BMW model and verify the part number 633-31082L before installation. Clean the rotor surface to remove any protective coating before mounting. Use proper torque specifications on the 5 lug bolts (14.6 mm diameter) arranged on a 120 mm bolt circle diameter. It is recommended to replace brake pads simultaneously to ensure optimal braking performance and rotor longevity.
