What is Spec-37 iron?

Spec-37 is a proprietary iron alloy developed by Wilwood. It offers higher tensile strength and improved thermal stability compared to standard cast iron, helping to resist warping and cracking under high heat.

What does the curved vane design do?

The curved internal vanes are designed to create a pumping action as the rotor spins. This helps to draw cooler air through the rotor and expel hot air, improving overall brake cooling efficiency.

Does this rotor come with hardware?

This listing is for the rotor only. Hardware, calipers, and brackets are typically sold separately and must be compatible with this specific rotor and your vehicle application.

Product Details

If you're looking to upgrade your braking system for more demanding use, a high-performance rotor like this Wilwood GT 72 is a solid choice. This is a right-side rotor, designed to work with specific Wilwood brake kits. It's built with Spec-37 iron, which is a proprietary material known for its ability to handle higher temperatures without warping, making it a good option for spirited driving or track days.

The rotor measures 12 inches in diameter and is 8.75 inches across the face, with curved vanes inside. These vanes help to move air through the rotor, aiding in cooling and preventing heat buildup. This improved thermal management means your brakes can perform more consistently, even under heavy use. The black finish isn't just for looks; it helps protect the rotor from corrosion when not in use.

This rotor is a component of a larger brake system, so it's important to ensure it's compatible with your specific Wilwood caliper and bracket setup. Proper installation is key to getting the most out of this performance part.
