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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors with enhanced cooling capabilities and surface designs that improve braking response. The drilled and slotted pattern helps reduce brake fade by allowing gases and heat to escape, while the zinc silver hat finish provides added protection against rust and corrosion. This product line is tailored for drivers seeking reliable rotor performance with a balance of durability and heat management.

Product Details and Specifications

This disc brake rotor features a vented design that promotes airflow between the rotor surfaces, reducing heat buildup during braking. The rotor’s 345 mm outside diameter and 78.6 mm overall height ensure compatibility with the BMW X5 and X6 models. The directional slotted and drilled surface improves water and debris removal, enhancing braking efficiency in wet or dusty conditions. The rotor’s bolt pattern includes five 16.6 mm diameter holes on a 120 mm bolt circle diameter, matching the factory specifications for these vehicles. Additionally, the zinc silver hat finish and rust-resistant coating help maintain rotor integrity over time.

Applications and Problem Solving

• Compatible with BMW X5 and X6 models requiring vented disc brake rotors
• Addresses brake fade caused by excessive heat during heavy braking
• Improves braking performance in wet or debris-prone environments
• Prevents premature rotor corrosion with rust-resistant coatings
• Maintains proper rotor thickness for safe and effective braking

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 22.4 mm before installation. Verify bolt hole alignment with the vehicle’s hub using the 120 mm bolt circle diameter and 16.6 mm bolt hole diameter. Clean the rotor surface to remove any protective coatings before mounting. Directional rotors must be installed following the indicated rotation direction to maintain optimal performance and safety.
