Watch in action

Wilwood GT48 Left Hand Vented Iron 2-Piece Brake Rotor

Engineered for the rigors of professional motorsports, the Wilwood GT48 Vented Iron rotor is designed to excel in extreme conditions. Its heavy-wall construction and directional curved vanes provide superior heat absorption and dissipation, effectively preventing heat fade and ensuring extended service life for both the rotor and brake pads. This makes it an essential component for any high-performance braking system.

Performance-Driven Features:

  • Material: Premium grade, long-grain carbon iron for exceptional wear, thermal stability, and resistance to distortion.
  • Design: Directional curved vanes for optimized airflow and cooling efficiency.
  • Machining: Fully detail machined to eliminate stress points and reduce weight away from the pad sweep face.
  • Precision: Faces and O.D. precision turned to less than .001" for flatness, parallelism, and run-out.
  • Slotting: Asymmetrical face slot pattern for smoother engagement, reduced harmonics, and improved thermal balance.
  • Dimensions: 12.88" diameter, 0.810" thickness, with a 12 on 8.75" bolt pattern.

This left-hand (LH) rotor is meticulously crafted to meet the demands of competitive racing, offering reliable performance and longevity. The precise machining and advanced slotting pattern contribute to a more stable and responsive braking experience, even under intense heat. Elevate your vehicle's braking capabilities with Wilwood's cutting-edge technology.
