Wilwood ULHP-32 Straight Vane Rotor

Universal Fitment

Part #: 160-5843

Overview

The Wilwood ULHP-32 Straight Vane Rotor is a high-performance brake component designed for both dirt and street applications. Crafted from premium long grain carbon iron, this rotor offers an optimal combination of efficient cooling, durability, and reduced rotating mass. It is ideal for racers and enthusiasts seeking reliable braking performance on demanding dirt tracks or rear axle service on pavement cars. The ULHP-32 rotor enhances braking response and heat dissipation, helping to maintain consistent pedal feel and prevent brake fade during intense driving conditions. Its precision-machined faces ensure smooth operation and minimal run-out, contributing to improved overall braking performance and driver confidence.

Key Features

This rotor features a straight vane design that promotes effective airflow and cooling, reducing the risk of overheating during prolonged use. The cast iron construction provides excellent wear resistance and long service life, even under high-stress conditions. Its precision turned faces with less than .001" variation in flatness, parallelism, and run-out ensure optimal contact with brake pads for consistent braking feel. The lightweight design helps reduce unsprung mass, supporting better handling and responsiveness. Designed for durability and performance, the ULHP-32 rotor is a reliable choice for both off-road and street applications requiring high thermal stability and resistance to distortion.

Construction & Design

Manufactured from long grain carbon iron, this rotor is engineered for superior thermal stability and long-term wear resistance. The precision machining process ensures flatness and parallelism, minimizing vibrations and uneven pad wear. The straight vane design facilitates efficient airflow across the rotor surface, aiding in heat dissipation and cooling during aggressive braking.

Driving Feel & Feedback

The ULHP-32 rotor provides a smooth, consistent braking response, supporting confident modulation and fade resistance. Its design helps maintain pedal feel and responsiveness, even under high thermal loads, making it suitable for demanding racing or spirited street driving.

Installation & Fitment

This rotor is designed for straightforward installation on compatible Wilwood brake systems. Proper fitment should be verified against vehicle specifications and part compatibility details.

What’s Included

The package includes one ULHP-32 straight vane rotor, ready for installation on suitable vehicles. Hardware or additional components are not included and should be sourced separately if required.
