• OE replacement vane configuration ensures proper and maximum heat dissipation

Quality Specifications:

• Disc Thickness Variation (DTV): 0.010mm maximum for consistent performance
• Lateral Runout: 0.050mm maximum to prevent pulsation and vibration
• Fine turned finish (16 RMS) for improved initial rotor and pad break-in
• Meets or exceeds OE standards for direct replacement installation
