Detailed Product Description

The DuraGo BR901680 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface. Its vented design enhances airflow to dissipate heat more effectively during braking, which helps maintain consistent stopping power and reduces the risk of rotor warping. With a nominal thickness of 1.18 inches and a discard thickness of 1.12 inches, this rotor meets OEM specifications for thickness tolerances, ensuring safe and reliable use throughout its service life.

Measuring 13.39 inches in outside diameter and featuring five mounting bolt holes on a 4.72 inch bolt circle diameter, the BR901680 is compatible with a range of BMW vehicles including the 228i, 320i xDrive, 335i, 430i Gran Coupe, and M240i xDrive. The rotor’s non-directional brake surface allows for flexible installation without concern for directional orientation, and the conventional rotor design fits standard caliper setups without integrated ABS tone rings.
