Detailed Product Description

The DuraGo BR900558-01 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface. Its vented design enhances airflow between the rotor surfaces, helping to dissipate heat more effectively during braking. This feature is critical for maintaining consistent brake performance and reducing the risk of brake fade under heavy use.

With a rust-resistant coating, this rotor is better protected against corrosion, extending its service life and maintaining optimal braking efficiency. The drum-in-hat construction integrates a parking brake drum within the rotor, making it compatible with BMW X3 models that use this setup. The rotor includes five mounting bolt holes arranged on a 120 mm bolt circle diameter, ensuring proper fitment and secure installation.
