Wilwood GT-48 Vented Iron Rotor – 12.88 x 0.81 inches for High-Performance Motorsports

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.

Designed for the demanding conditions of professional motorsports, the Wilwood GT-48 Vented Iron Rotor (Part Number: 160-9959) offers exceptional heat absorption and dissipation capabilities. Crafted from premium long grain carbon iron, these heavy wall rotors deliver superior thermal stability, resistance to distortion, and long-lasting wear. The fully detailed machining process ensures stress points are eliminated and unnecessary weight is reduced, resulting in improved structural integrity and performance. The precision turned faces and outer diameter to less than .001 inches guarantee flatness, parallelism, and minimal run-out, which are critical for consistent braking response. An asymmetrical face slot pattern is incorporated to provide smoother engagement by reducing harmonic vibrations and balancing thermal expansion between the inner and outer diameters. Each rotor is individually dynamically balanced, ensuring vibration-free operation at high speeds, making it ideal for short track and road course racing conditions. These rotors are engineered to provide maximum cooling capacity, extending service life and maintaining optimal braking performance during intense competition. Whether used for professional racing or high-performance driving, the Wilwood GT-48 rotor combines advanced engineering with durability, ensuring reliable braking under extreme conditions.
