Wilwood 160-17517 Curved Vane Disc Brake Rotor - GT-36 Spec-37

The Wilwood 160-17517 is a GT-36 Curved Vane Spec-37 disc brake rotor engineered for the extreme demands of professional motorsports, including short track and road course competition. Cast from Wilwood's proprietary Spec-37 long-grain carbon iron alloy — a formulation derived from the same technology used in Wilwood's extreme-duty military-specification rotors — this rotor delivers exceptional resistance to distortion, warping, cracking, and wear under the most punishing heat cycles.

Key Features:

• 36 curved directional vanes with heavy-wall construction for maximum heat absorption and dissipation, preventing heat fade and extending rotor and pad service life
• Spec-37 proprietary iron alloy — developed for extreme-temperature stability and dimensional integrity under sustained racing conditions
• Precision-machined faces and O.D. turned to less than .001" for flatness, parallelism, and runout, eliminating stress points and reducing unnecessary weight away from the pad sweep face
• Asymmetrical face slot pattern for smoother engagement through reduced harmonics and improved thermal balance between the inner and outer diameter of the rotor
• Individually dynamic balanced to ensure vibration-free braking performance at any speed
• Fully detail machined to eliminate stress concentration points
• Directional vane design — must be installed on the correct side of the vehicle

The GT-36 curved vane design provides the highest cooling capacity available in the GT rotor series, making the Wilwood 160-17517 the ideal choice for racers who demand consistent, fade-free stopping power through extended sessions. Whether on a short oval or a demanding road course, this rotor is built to deliver race-proven reliability lap after lap.
