What is the benefit of a 2-piece rotor design?

A 2-piece rotor design allows the rotor ring to expand and contract with heat independently of the center hat. This reduces stress on the rotor, helping to prevent cracking and warping, especially under high temperatures.

What is Spec-37 iron?

Spec-37 is a proprietary iron alloy developed by Wilwood. It is known for its high tensile strength and thermal stability, making it well-suited for high-performance braking applications where rotors are subjected to extreme heat.

What is the purpose of the 48 vanes?

The 48 internal vanes are designed to create turbulence and channel air through the rotor. This increased airflow helps to carry heat away from the braking surface more efficiently, reducing the risk of brake fade during hard use.

Product Details

Wilwood is well-known for making high-performance braking components, and this 2-piece rotor is a prime example of their focus on track-ready performance. This rotor is designed for demanding applications where consistent stopping power and heat management are critical. It's built to handle the rigors of spirited driving and track use, offering a significant upgrade over standard factory rotors.

This particular rotor features a 48-vane internal vane structure. More vanes mean better airflow through the rotor, which helps dissipate heat more effectively. Keeping temperatures down is crucial for preventing brake fade, especially during extended periods of hard braking. The rotor itself is cast from Wilwood's proprietary Spec-37 iron alloy, which is known for its strength and ability to withstand high temperatures without warping. The 2-piece design allows the rotor ring to expand and contract independently of the hat, further reducing stress and the risk of cracking under thermal load. The hat is made from aluminum for weight savings and corrosion resistance.

This rotor is designed to be a direct replacement for specific applications, often used in conjunction with Wilwood's own brake kits. It includes a snap ring for secure assembly. When installing, ensure you follow Wilwood's recommended procedures for proper bedding-in to achieve optimal performance and longevity.
