Key Features:

• Drilled Design: Cross-drilled holes promote heat dissipation, reduce brake fade, and help expel gas and debris from the braking surface for consistent, confident stopping
• G3000 Grade Cast Iron Construction: High-grade cast iron provides the durability and thermal stability required for long-lasting braking performance
• Zinc Plated Finish: Corrosion-resistant zinc coating protects the rotor hub and non-braking surfaces from rust, extending rotor life and maintaining a clean appearance
• OEM Direct-Fit Replacement: Designed to match original equipment specifications for a hassle-free, bolt-on installation
• Driver Side (Left): This rotor is specifically designed for the left/driver-side position — confirm fitment before ordering
• Vented Design: Internal vanes promote airflow through the rotor to continuously cool the braking surface during use
