Wilwood 160-13807 Curved Vane Disc Brake Rotor - GT60 Spec-37 15x1.25 LH

The Wilwood 160-13807 is a GT60 Curved Vane Spec-37 disc brake rotor engineered for serious motorsports competition. Measuring 15.00" in diameter x 1.25" thick with a 12-bolt, 10.25" bolt circle pattern, this is a left-hand (LH) directional rotor built to deliver maximum braking performance on short tracks and road courses.

Key Features:

• Spec-37 Proprietary Iron Alloy: Cast from a military-derived iron alloy formulation engineered for extreme heat resistance with the highest degree of protection against distortion, warping, cracking, and wear
• GT Series Asymmetrical Face Slot Pattern: Reduces harmonics for smoother, more consistent pad engagement and improved thermal balance across the rotor face
• Individual Dynamic Balancing: Every rotor is individually balanced for vibration-free performance at all speeds
• Precision Machined: Each rotor is machined to less than .001" run-out, flatness, and parallelism for optimal contact and longevity
• 60 Curved Vanes: High-vane-count curved vane design maximizes airflow through the rotor for superior heat dissipation and cooling capacity
• Left-Hand (LH) Directional: Vane curvature optimized for the left-side application to maximize cooling efficiency

The Spec-37 iron alloy used in this rotor traces its development to the extreme-duty military specification rotors manufactured by Wilwood, making it one of the most thermally stable and durable rotor materials available for competition use. This rotor is purpose-built for the demands of high-intensity braking in short track oval and road course racing environments.
