Wilwood 160-8398-GTB GT Curved Vane Disc Brake Rotor - 72 Spec-37

The Wilwood 160-8398-GTB is a high-performance GT 72 Curved Vane Spec-37 disc brake rotor engineered for extreme braking conditions. Manufactured from Wilwood's proprietary iron alloy, this rotor delivers exceptional thermal stability and durability under the most demanding applications.

Advanced Material Technology:

• Proprietary Spec-37 iron alloy derived from military-grade rotor technology
• Exceptional resistance to distortion, warping, cracking, and wear
• Engineered to withstand extreme temperatures without performance degradation
• 72 curved vane design for superior heat dissipation

Performance Features:

• GT Series asymmetrical face slot pattern for consistent pad contact and gas evacuation
• Individually dynamically balanced for smooth, vibration-free braking
• Curved vane configuration maximizes airflow and cooling efficiency
• Proven design for both street and track applications

This rotor combines race-proven technology with materials engineering to deliver reliable, fade-resistant braking performance. The asymmetrical slot pattern helps prevent pad glazing while evacuating gases and debris, while the precision balancing ensures smooth operation at all speeds.
