• Five bolt holes with a diameter of 14.6 mm
• Rotor height of 60.5 mm

Detailed Product Specifications

This disc brake rotor features a vented design that enhances airflow between the rotor surfaces, reducing heat buildup during braking. The drilled pattern further assists in dissipating heat and preventing brake fade, which is critical for maintaining consistent stopping power. With an outside diameter of 320 mm and an inside diameter of 75 mm, this rotor fits securely on the specified BMW models. The five bolt holes, each measuring 14.6 mm in diameter, ensure proper mounting and alignment. The nominal thickness of 21.8 mm provides a solid braking surface, while the discard thickness of 20.4 mm indicates when the rotor should be replaced to maintain safety and performance.

About the DFC GEOSPEC Coated Rotor - Drilled Line
