What is the primary benefit of the curved vane design on these rotors?

The curved vane design, along with the directional vanes, is engineered to significantly improve heat absorption and dissipation. This helps prevent brake fade during intense use and extends the service life of the rotors and pads.

What material are these Wilwood rotors made from?

These rotors are cast from a premium grade, long grain carbon iron. This material is chosen for its durability, resistance to distortion under heat, and long wear characteristics.

Are these rotors balanced for smooth operation?

Yes, each rotor is individually dynamically balanced. This process ensures vibration-free performance, which is crucial for consistent braking feel and reducing wear on other suspension components.

Product Details

These Wilwood GT48 rotors are built with a curved vane design, measuring 12.88 inches in diameter and 1.10 inches thick. This specific design is intended for the demanding conditions found in professional motorsports, where managing heat is critical. The heavy wall construction and directional vanes work together to absorb and dissipate heat effectively, which helps prevent brake fade and extends the life of both the rotors and your brake pads.

Cast from a premium grade, long grain carbon iron, these rotors are made to resist wear, maintain thermal stability, and avoid distortion under stress. Wilwood machines every GT rotor to remove stress points and excess weight from the pad sweep area. The faces and outer diameter are turned precisely to within .001 inches for flatness, parallelism, and run-out, ensuring smooth operation. An asymmetrical face slot pattern is used to reduce harmonics and improve thermal balance across the rotor, leading to smoother braking and vibration-free performance at any speed.

For those pushing their vehicles in short track or road course competition, these rotors offer a high cooling capacity and a long service life. They are dynamically balanced individually to ensure vibration-free performance.
