Wilwood 160-3314-B GT48 Curved Vane Spec-37 Disc Brake Rotor Right Hand Bedded

The Wilwood 160-3314-B is a GT48 Curved Vane Spec-37 disc brake rotor engineered for extreme-duty motorsports applications. Measuring 12.72" in diameter by 1.38" wide with a 12-bolt, 6.75" bolt circle, this right-hand directional rotor arrives factory-bedded and ready for competition use.

Cast from a proprietary Spec-37 iron alloy — a material whose formulation draws directly from Wilwood's development of military-specification rotors — this rotor delivers outstanding resistance to distortion, warping, cracking, and wear under sustained extreme heat. The heavy-wall Spec-37 casting is well suited for moderate-to-high temperature racing environments including short track and road course competition.

Key Features:

• 48 curved directional vanes for maximum airflow and cooling capacity
• GT Series asymmetrical face slot pattern reduces harmonics and promotes even thermal balance across the rotor face
• Individual dynamic balancing ensures smooth, vibration-free braking at all speeds
• Precision machined to less than .001" run-out, flatness, and parallelism
• Factory bedded surface — pre-conditioned for immediate race-ready use
• Right-hand (RH) directional design — rotor is side-specific; confirm correct side before ordering
• Sold individually

The Wilwood 160-3314-B GT48 Spec-37 rotor is purpose-built for serious oval track and road racing competitors who demand the highest levels of braking consistency, fade resistance, and long service life under repeated hard stops.
