Designed with a durable silver-gray rust-prevention coating applied inside and out, this rotor delivers superior corrosion protection compared to conventional zinc or painted finishes.

• Fully coated inside and out — all surfaces protected with high-quality rust-prevention coating for long-lasting durability before and after installation
• Ready to install — processed dry and shipped dry, requiring no additional cleaning or degreasing, saving significant time during installation
• Brake-friendly coating — GeoSpec coating is designed not to contaminate friction surfaces, ensuring proper bed-in and consistent wear characteristics

Premium Construction:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and long-term durability
• OE vane configuration duplicated precisely to ensure proper and maximum heat dissipation
• CNC-machined to the tightest tolerances for exact OEM form, fit, and function
• 100% precision cut and mill-balanced for smooth, vibration-free stopping at any speed
• Non-directional surface finish promotes a faster, more even brake pad bed-in and quieter stops
• 100% inspected at the factory — all critical attributes measured before shipment
