• Black zinc-coated hat finish for corrosion resistance
• Rust resistant coating applied to rotor surface
• Overall diameter of 300 mm with 5 lug holes (14.6 mm diameter)
• Nominal thickness of 20 mm and discard thickness of 18.4 mm
• Bolt circle diameter of 120 mm and center hole diameter of 75 mm

Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Black from Dynamite Friction is designed to meet the specific braking requirements of the BMW Z4. Its vented construction allows air to flow between the rotor surfaces, helping to dissipate heat and reduce brake fade during aggressive driving or repeated stops. The rotor’s surface is both drilled and slotted in a directional pattern, which aids in removing brake dust, gases, and water from the contact area, improving overall braking consistency.

The rotor features a plain disc finish combined with a zinc black hat finish that provides enhanced corrosion resistance, extending the rotor’s service life. With a nominal thickness of 20 mm and a discard thickness of 18.4 mm, this rotor maintains structural integrity and performance throughout its lifespan. The 5-bolt hole pattern with a 120 mm bolt circle diameter ensures proper fitment and secure mounting on the BMW Z4.

About the 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 corrosion-resistant black zinc finish on the hat. This product line is engineered to provide enhanced heat dissipation and improved braking performance while offering protection against rust and corrosion, making it suitable for drivers who demand reliable stopping power and durability.

Common Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust accumulation for cleaner braking surfaces
• Prevents rust and corrosion on rotor hats and surfaces
• Maintains consistent braking performance under aggressive driving conditions

Installation Notes and Tips

Ensure the rotor is installed on a compatible BMW Z4 model with matching bolt pattern and dimensions. Verify the rotor thickness before installation; replace if below the discard thickness of 18.4 mm. Clean the rotor surface of any protective coatings or oils before mounting to ensure optimal brake pad contact. Properly torque lug nuts to manufacturer specifications to avoid rotor warping.
