Product Details  

The Wilwood GT48 Directional Brake Rotor (Part #160-8746) is a premium-performance brake rotor engineered for professional motorsports, heavy-duty performance vehicles, and demanding street applications. Featuring a 12.60-inch outside diameter, 1.29-inch nominal thickness, and a right-hand (passenger side) directional curved vane design, this rotor delivers superior cooling efficiency, exceptional heat management, and consistent braking performance under extreme operating conditions. It is manufactured from Wilwood's proprietary Spec-37 high-carbon iron alloy, offering outstanding resistance to distortion, warping, cracking, and wear.

The GT48 rotor incorporates 48 curved internal cooling vanes that maximize airflow through the rotor, helping to reduce operating temperatures and brake fade during repeated hard braking. Its GT asymmetrical slotted friction surface continuously cleans the brake pads, improves gas evacuation, and promotes even pad wear for consistent pedal feel. Every rotor is individually dynamically balanced to minimize vibration and ensure smooth operation at high speeds.

Ideal for road racing, circle track, rally, stock cars, off-road competition, industrial, and high-performance street vehicles, the Wilwood 160-8746 rotor is built to deliver reliable stopping power and long service life.
