What makes the GT48 rotor suitable for motorsports?

The GT48 rotor is built for extreme conditions with its heavy wall construction and directional curved vanes. This design provides superior heat absorption and dissipation, which is key to preventing brake fade and extending the life of both the rotors and pads during intense use.

What material are these rotors made from and why is it important?

These rotors are cast from a premium grade, long grain carbon iron. This specific material is chosen for its long wear characteristics, resistance to distortion, and thermal stability, making it well-suited for high-performance braking applications.

How does the asymmetrical face slot pattern benefit braking performance?

The asymmetrical face slot pattern is designed to create smoother engagement during braking by reducing harmonics. It also helps to improve the thermal balance between the inner and outer parts of the rotor, contributing to more consistent performance.

Product Details

This is a Wilwood GT48 vented iron brake rotor, part number 160-9959. It's a 12.88-inch diameter rotor with a thickness of 0.810 inches, designed with a 12-vane curved vane pattern and a 12-on-8.75-inch bolt circle. These rotors are constructed for the demanding conditions found in professional motorsports, where managing heat is critical to performance and component longevity.

The GT48 rotors are made from a premium grade, long grain carbon iron. This material choice helps ensure long wear, stability under heat, and resistance to warping. Wilwood machines every rotor to remove stress points and excess weight, while also ensuring the faces are flat and parallel to within .001 inches. The unique asymmetrical face slot pattern is designed to reduce vibration and improve how heat is managed across the rotor's surface, from the inner diameter to the outer edge. Each rotor is also dynamically balanced to guarantee smooth operation at any speed.

If you're pushing your vehicle hard on the track or in competition, these rotors offer high cooling capacity and are built for extended service life. They are intended for use in extreme braking situations on short tracks and road courses.
