Detailed Product Description

The DuraGo BR900736 disc brake rotor is engineered with a full cast construction using high-quality cast iron, providing a balance of durability and effective heat management. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent stopping power. The drum-in-hat style integrates a parking brake drum within the rotor, eliminating the need for a separate drum and simplifying installation on compatible BMW models.

With an outside diameter of 320 mm and a nominal thickness of 20 mm, this rotor meets OEM specifications for the listed BMW vehicles. The five mounting bolt holes with a 120 mm bolt circle diameter ensure a secure fit, while the non-directional brake surface allows for flexible rotor placement without concern for directional rotation. Note that this rotor does not include an ABS tone ring and does not feature rust-resistant coating, so proper maintenance is recommended to prevent corrosion over time.
