Detailed Product Description

This Dynamite Friction rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering enhanced braking efficiency through advanced rotor surface technology. The combination of drilled holes and precision slots helps to reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. The vented rotor design further aids in cooling, maintaining consistent braking performance under demanding conditions.

The rotor’s plain disc finish paired with a Geospec silver grey hat finish provides corrosion resistance and a clean appearance. The rust resistant coating extends the rotor’s service life, especially in environments prone to moisture and road salt. With a 5-lug bolt pattern and precise dimensions, this rotor is engineered for direct compatibility with select BMW 3 Series and X1 models.

Applications and Problem Solving

• Replaces worn or warped rotors on BMW 335d, 335i, 335is, 335i xDrive, 335xi, and X1 models
• Addresses brake fade caused by overheating during aggressive driving or towing
• Improves braking response and reduces noise from glazing or uneven rotor surfaces
• Helps prevent rust and corrosion-related rotor damage
• Enhances overall brake system durability and performance

Installation Notes and Tips

Ensure the rotor is installed on compatible BMW models listed in the fitment. Verify the bolt hole pattern (5 holes, 14.6 mm diameter, 120 mm bolt circle) matches your vehicle’s hub. Clean the hub surface before installation to ensure proper rotor seating. Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors for optimal performance.
