Wilwood disc brake rotors address the key elements in high performance rotor design: Optimum mechanical advantage, material stability under thermal cycling, material resistance to thermal shock, heat disbursing efficiency and rotating weight vs task required to perform.

Curved Vane Rotors

GT Series Cured VaneHD rotor.jpg

GT-36 and GT-48 vane rotors are built for the extreme conditions of professional motorsports. The superior heat absorption and dissipation characteristics of these heavy wall directional vane rotors are the keys to preventing heat fade and realizing long service life from the rotors and pads. All rotors are cast from premium grade, long grain carbon iron for long wear, thermal stability, and resistance to distortion.

Heavy Duty Curved VaneHD rotor.jpg

HD Series Rotors provide superior thermal stability and long service for most types of asphalt late models, modifieds, and open wheel category competition. All HD series rotors are manufactured from premium grade, long grain carbon iron for long wear, high thermal stability and resistance to distortion. Thick wall pad sweep faces with directional cooling vanes provide superior heat absorption and dissipation qualities to prevent heat fade and realize long service life from the pads and rotors. All HD rotor faces are precision turned to less than .001" for flatness, parallelism, and run-out for smoother engagement and reduced vibration.

Light Duty Curved VaneUL rotor.jpg

Ultra-Light UL- 32 and ULHP- 32 directional vane rotors provide an excellent balance of efficient cooling and lower rotating mass on hard braking dirt tracks or rear axle service on pavement cars. UL rotors are cast from premium grade, long grain carbon iron for long wear, high thermal stability, and resistance to distortion. UL- 32 rotors are production machined and well suited to a wide range of sportsman racing categories. ULHP- 32 rotors offer the added performance and smoother operation of precision turned faces with less than .001" variation in flatness, parallelism, or run-out.

Straight Vane RotorsLite rotor.jpg

Ultra-Light UL and ULHP straight vane rotors provide high value performance and rugged durability for a wide range of competition, high performance, and sport driving applications. Don't confuse these rotors with bargain priced off-brand named parts. Wilwood's modern manufacturing capability, combined with large scale economies, make it possible to offer this level of quality and performance at such an affordable price. Every Wilwood rotor is cast from premium grade, long grain carbon iron. This material exhibits long wear, high thermal stability, and excellent resistance to distortion in high heat. Modern foundry and machining techniques hold close tolerances on face and vane thickness.

Rotor HatsHat.jpg

Wilwood's HD Series Fixed Mount Rotor Hats have a long standing reputation for fit, performance, and durability. HD Series hats are manufactured from premium grade aluminum alloys offering high strength, low weight, and show quality appeal. HD hats have not only been a mainstay in many of Wilwood's racing disc brake conversion kits, but they can cover a range of applications from an OE four lug axle shaft to a Grand National stock car racing hub. HD hats feature a straight bell construction with a flanged rotor mount ring. These features combine to provide maximum radial clearance between the caliper body and the hat. This can be a critical factor when trying to squeeze a large caliper inside a small wheel. Many hats offer multi-lug wheel patterns for added versatility. Some hats can be ordered blank for custom axle building and other unique applications.

The HD hat configurations are divided into two groups. There are threaded hole hats for use with through-hole mount rotors, and there are through-hole mount hats for use with threaded hole rotors. When used with matching Wilwood rotor hardware, these hats provide solid mounting for a wide range of custom and competition disc brake applications. Use the ordering information link to match the rotor mount, lug pattern, offset, and the other dimensions necessary for each application.
