Detailed Product Description
The DuraGo BR31166 is a vented disc brake rotor designed specifically for the Lexus LS400, providing a balance of durability and thermal management. Made from full cast iron, this rotor offers structural integrity and resistance to warping under heat stress. The vented design allows air to flow between the rotor surfaces, reducing brake fade during extended use.
