DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a directional surface pattern. This design improves water and gas evacuation from the rotor surface, reducing brake fade and maintaining consistent braking performance under demanding conditions. The zinc black hat finish and rust-resistant coating extend rotor life by protecting against corrosion, making it suitable for BMW vehicles that require both performance and durability.

Detailed Product Description

This disc brake rotor is vented to allow air circulation between the rotor faces, which helps dissipate heat generated during braking. The drilled and slotted surface enhances pad bite and helps remove brake dust and moisture, improving braking efficiency. The rotor’s directional design ensures optimal performance when installed correctly. With a bolt hole diameter and stud/lug hole diameter of 14.5 mm and a 5-bolt pattern on a 120 mm bolt circle, this rotor fits securely on compatible BMW models. The zinc black hat finish combined with a rust-resistant coating protects the rotor from corrosion, extending its service life.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup during aggressive driving or towing
• Improves braking response in wet or humid conditions by evacuating water from the rotor surface
• Minimizes brake dust accumulation for cleaner brake components and improved pad contact
• Prevents premature rotor corrosion with rust-resistant coating and zinc black finish
• Ensures consistent braking performance on BMW 220i, 328i xDrive, 330i, and X1 models

Installation Notes and Tips

• Verify compatibility with your specific BMW model and year before installation
• Ensure proper orientation of the directional rotor surface for optimal performance
• Inspect brake pads and hardware during rotor replacement for best results
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Allow a proper bedding-in period after installation to maximize rotor and pad performance
