What is the primary benefit of the curved vane design?

The curved vane design, along with the heavy wall construction, is engineered for superior heat absorption and dissipation. This helps prevent brake fade during extreme use and extends the service life of the rotors and pads.

What material is this rotor made from and why is it important?

This rotor is cast from a premium grade, long grain carbon iron. This material is chosen for its long wear characteristics, thermal stability, and resistance to distortion, which are crucial for high-performance braking.

Does this rotor come with any hardware?

This product listing is for the brake rotor only. Installation hardware, such as bolts or nuts, is typically sold separately and should be confirmed with the manufacturer's specifications for your application.

Product Details

The GT48 rotor features a curved vane design, measuring 12.88 inches in diameter and 1.10 inches thick. This design is specifically built to handle the intense heat generated during professional motorsports, helping to prevent brake fade and extend the life of both the rotors and your brake pads. The heavy wall construction and directional vanes work together to absorb and dissipate heat effectively.

Wilwood casts these rotors from a premium grade, long grain carbon iron. This material choice is key for long wear, thermal stability, and resisting distortion under stress. Each rotor is then meticulously machined to remove stress points and excess weight from the pad sweep area. The faces and outer diameter are precision-turned to ensure flatness and parallelism, with run-out kept to less than .001 inches. An asymmetrical face slot pattern is used to reduce harmonics and improve thermal balance across the rotor, leading to smoother engagement and vibration-free performance at any speed.

This rotor is dynamically balanced individually to ensure smooth operation. It's a solid option for those pushing their braking systems to the limit on short tracks or road courses, offering high cooling capacity and a long service life.
