Detailed Product Description

The DuraGo BR900214 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 the braking system on the INFINITI Q45.

With a precise outside diameter of 11.5 inches and a nominal thickness of 0.63 inches, this rotor meets the exact specifications required for the INFINITI Q45, ensuring proper fitment and optimal braking performance. The five mounting bolt holes with a 4.5 inch bolt circle diameter align perfectly with the vehicle’s hub assembly. The non-directional brake surface allows for flexible installation without concern for rotor orientation.
