Wilwood 160-17531 Ultralite HP 32-Vane Iron Disc Brake Rotor Plain Face 12.19"

The Wilwood 160-17531 is a right-hand Ultralite HP 32-Vane Disc Brake Rotor built from long-grain carbon iron and precision-machined to meet the demands of competition and severe-duty applications. With a 12.19-inch outside diameter and 0.81-inch width, this plain-face rotor integrates a 32-vane internal cooling design and an integral hat for a complete, ready-to-install assembly.

Key Features:

• Ultralite HP Series: Added mass compared to standard HP rotors extends service life under heavy competition loads and severe-duty use while maintaining a reduced overall weight profile
• Long-Grain Carbon Iron Construction: Superior thermal conductivity and dimensional stability resist heat-induced distortion, warping, and fatigue under repeated hard braking cycles
• Close-Tolerance Machining: Each rotor is precision-machined to less than .001" tolerance for overall flatness, parallelism, and radial run-out, ensuring consistent pad contact and pedal feel
• Smooth Turned Pad Face: Factory-smooth friction surface promotes even pad seating and optimal bite right out of the box
• 32-Vane Internal Cooling: High vane count maximizes airflow through the rotor to draw heat away from the friction surface during aggressive use
• Integral Hat Design: Combined rotor and hat construction simplifies installation and reduces component count
• Plain Face Surface Finish: Non-drilled, non-slotted face for maximum friction surface area and durability

Designed as both a high-performance competition component and a robust everyday street rotor, the Wilwood 160-17531 delivers consistent, fade-resistant stopping power whether used on the track or on the road. It is sold as a single right-hand rotor.
