• Directional drilled and slotted surface for improved brake pad bite and debris removal
• Vented rotor design to reduce heat buildup during braking
• Zinc black hat finish with rust-resistant coating for corrosion protection
• Overall diameter of 365 mm and nominal thickness of 36 mm
• Five bolt holes with 16.6 mm diameter and 120 mm bolt circle diameter
• Discard thickness of 34.4 mm to indicate rotor replacement threshold

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black is constructed with a vented rotor design that allows air to flow between the rotor surfaces, helping to dissipate heat more effectively during heavy braking. The directional surface pattern combines drilled holes and slots to improve water and gas evacuation, which can enhance braking consistency and reduce brake fade. The rotor's hat is finished in zinc black, providing a rust-resistant coating that extends the rotor's service life by protecting against corrosion. With an outside diameter of 365 mm and a nominal thickness of 36 mm, this rotor meets the precise specifications required for BMW X5 and X6 models. The five bolt holes, each 16.6 mm in diameter, are arranged on a 120 mm bolt circle diameter, ensuring proper fitment and secure mounting.
