Wilwood GT-48 Vented Iron Rotor for High-Performance Motorsports - Part Number 160-9960

GT-48 curved vane rotors are built for the extreme conditions of professional motorsports. The superior heat absorption and dissipation characteristics of these heavy wall directional vane rotors are the keys to preventing heat fade and realizing long service life from the rotors and pads. All rotors are cast from premium grade, long grain carbon iron for long wear, thermal stability, and resistance to distortion. Every GT rotor is fully detail machined to eliminate stress points and unnecessary weight away from the pad sweep face. The faces and O.D. are precision turned to less than .001" for flatness, parallelism, and run-out. An asymmetrical face slot pattern provides smoother engagement through reduced harmonics and improved thermal balance between the I.D. and O.D. of the rotor. Every rotor is then individually dynamic balanced to provide vibration free performance at any speed. These rotors provide the highest cooling capacity and longest service life for extreme braking short tracks and road course competition.

The Wilwood GT-48 Vented Iron Rotor (Part Number 160-9960) is engineered for demanding motorsports applications, offering exceptional heat management and durability. Crafted from high-quality long grain carbon iron, this rotor provides superior thermal stability, resistance to distortion, and long service life, making it ideal for short track and road course racing. The heavy wall, directional vane design enhances heat absorption and dissipation, preventing heat fade during intense braking conditions. Fully precision machined, the rotor features a flatness and parallelism accuracy of less than .001 inch, ensuring optimal contact and performance. The asymmetrical face slot pattern reduces harmonic vibrations, providing smoother engagement and better thermal balance between the inner and outer diameters. Each rotor is individually dynamically balanced to deliver vibration-free performance at any speed, ensuring consistent braking response for competitive racing environments. The design also emphasizes cooling capacity, helping to maintain consistent brake temperatures and prolong component life. This rotor is suitable for systems with a 12.88-inch diameter and 0.81-inch thickness, compatible with 12 on 8.75-inch bolt pattern hubs. Built for extreme conditions, the Wilwood GT-48 rotor combines advanced engineering and durable materials to deliver reliable, high-performance braking for professional motorsports applications.
