The Wilwood HD 48 Curved Vane Spec-37 rotors are high-performance brake components designed for extreme duty applications. Constructed from a proprietary iron alloy developed to endure high temperatures, these rotors offer exceptional resistance to distortion, warping, cracking, and wear. Precision machined to less than .001 inches run-out and flatness, they ensure optimal braking performance and consistency under demanding conditions. The curved vane design enhances heat dissipation, reducing brake fade during intense use, making these rotors ideal for racing, heavy-duty towing, or aggressive driving scenarios.
These rotors are suitable for a variety of vehicles requiring 12.19-inch diameter, 7.62-inch height, and 1.25-inch thickness rotors. They are engineered to fit specific applications where high thermal capacity and durability are critical. Installation involves direct replacement of existing rotors, providing a reliable upgrade for vehicles subjected to extreme braking demands. The kit includes the rotors themselves, designed to deliver improved braking response and longevity in demanding street or track environments.

Overview
Overview
Wilwood's HD 48 Curved Vane Spec-37 rotors are manufactured from a proprietary iron alloy developed to withstand extreme temperatures with the highest possible degree of resistance against distortion, warping, cracking, and wear. The formulation for this alloy is a derivative of technology and materials that were significant in the development of the extreme duty military spec rotors that are manufactured by Wilwood. Every Spec 37 rotor is precision machined to less than .001" run-out, flatness, and parallelism. Our HD Series preparation includes full detail machining and smooth pad contact faces without slots.
Wilwood is a leading manufacturer of high-performance brake systems and components to fit a wide range of track and street applications. They offer everything from individual components like rotors, calipers, and pads to complete bolt-on kits.
Wilwood Engineering designs and manufactures high-performance disc brake systems. Since the company’s inception in 1977 by Bill Wood, we have developed a substantial matrix of brake components and engineering techniques that allow us to quickly and reliably create brake systems for almost any application. Our core ability is the rapid development of custom engineered brake systems using a combination of off-the-shelf and custom components. In addition to designing and manufacturing brakes for all types of competitive motorsports, Wilwood also manufactures brake systems and components for agricultural equipment, industrial applications, utility vehicles, snowmobiles, quads, motorcycles and military vehicles.
With headquarters in Camarillo, California, Wilwood employs approximately 320 people. We have on-shelf stock of more than 300 different brake calipers, 200 rotor designs, 100 master cylinder designs and a wide assortment of brackets, fittings, valves and brake lines. Our off-shelf brake calipers range in size from tiny calipers used on go-carts and light duty industrial equipment to heavy-duty original equipment brakes for the U.S. military Humvee.
Wilwood's engineering department uses the latest computer-aided design and manufacturing techniques in conjunction with finite element analysis, dynamic test and cycle test equipment to find high-performance and reliability solutions for the most difficult braking tasks. Our extensive inventory of proprietary on-the-shelf components allow us to provide cost-effective solutions for unique brake applications.
Wilwood is ISO 9000 compliant and has extensive experience maintaining quality levels of 100ppm or less for original equipment manufacturers.
