GT Series Directional Vane Rotors:

The GT Series 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.

Every GT rotor is fully detail machined to eliminate stress point and unnecessary weight away from the pad sweep face. The faces and O.D. are precision turned to less than .001" for flatness, parallelism, and run-out. An asymmetrical face slot pattern provides smoother engagement through reduced harmonics and improved thermal balance between the I.D. and O.D. of the rotor. Every rotor is then individually dynamic balanced to provide vibration free performance at any speed. These rotors provide the highest cooling capacity and longest service life for extreme braking short tracks and road course competition.

GT-36 Curved Vane Slotted Rotors

Wilwood's GT 36 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. Combined with our proven GT Series asymmetrical face slot pattern and individual dynamic balancing, you are assured the smoothest braking available.

SRP Drilled and Slotted Performance Rotor

SRP Drilled Performance Rotors feature a specially engineered directional cross drill and face slot pattern that improve brake response and pad performance throughout the entire range of light to heavy braking. The venting and cleaning action of the holes and slots will reduce pad glaze and disperse gasses and heat generated during the pad to rotor interface. The holes and slots also inhibit irregular pad compound build-up on the rotor faces resulting in smoother engagement and improved pedal response in all conditions. The material removed also contributes to lower rotating and unsprung suspension weight.

Specifications

• Diameter: 11.75" (298.5mm)
• Width: 0.81" (20.6mm)
• Bolt Circle: 8 x 7.00" (177.8mm)
• Hole Type: 0.326"
• Far Side I.D.: 8.34" (211.8mm)
• Lug I.D.: 6.38" (162.0mm)
• Weight LBS: 9 lbs.

Performance characteristics

• Premium grad, medium weight castings
• Suitable for moderate temperature racing to street use

Along with the excellent performance characteristics of this rotor design, each rotor is treated with a black electro coat to inhibit corrosion on all areas of the rotor. The high tech design, classic style, and aesthetic appeal of the SRP series are the perfect finishing touches to any wheel and tire detail.
