Detailed Product Description

The DuraGo BR900578 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface. Its vented design enhances airflow between the rotor faces, helping to reduce heat buildup during braking and maintain consistent stopping power. With a nominal thickness of 1.18 inches and a discard thickness of 1.06 inches, this rotor offers a balance between longevity and performance. The rotor measures 13.15 inches in outside diameter and features a 5-bolt mounting pattern with a 4.5 inch bolt circle diameter, ensuring proper fitment on compatible Lexus GS and IS series models. The non-directional brake surface allows for flexible installation without concern for rotor orientation. This conventional rotor does not include an ABS tone ring, so it is intended for vehicles where this feature is not required.
