What is the primary benefit of the proprietary iron alloy used in this rotor?

The proprietary iron alloy is specifically formulated to withstand extreme temperatures. This provides a high degree of resistance against distortion, warping, and cracking, which is crucial for heavy-duty braking applications.

What does the '48 Curved Vane' designation mean for this rotor?

The 48 curved vanes are internal passages within the rotor that help to move air. This airflow aids in dissipating heat generated during braking, helping to keep the rotor temperatures down and maintain consistent performance.

Does this rotor come with mounting hardware or a hat?

The provided description indicates this is a two-piece rotor design, which typically includes a separate hat. However, specific details about included hardware or the hat are not provided in the manufacturer's description.

Product Details

Wilwood has a reputation for building serious braking components, and this HD 48 Curved Vane rotor is a prime example. It's designed for vehicles that push their brakes hard, where heat can be a real issue. This rotor measures 13.06 inches in diameter with a 1.25-inch thickness and features 48 curved vanes to help move air and dissipate heat.

What sets this rotor apart is the material: a proprietary iron alloy that Wilwood developed. This alloy is a direct descendant of the technology they use for extreme-duty military spec rotors, meaning it's formulated to stand up to intense heat without distorting, warping, or cracking. The machining is precise, with smooth pad contact faces that ensure consistent engagement with your brake pads.

Because this is a two-piece rotor design, it's important to ensure it's compatible with your existing brake system or any aftermarket upgrades you might be considering. Always refer to your vehicle's service manual or consult with a professional to confirm fitment and installation requirements.
