Raybestos 781099FZN Element3 RPT Rust Prevention Technology Coated Rear Disc Brake Rotor

The Raybestos 781099FZN is an Element3 coated rear disc brake rotor featuring Raybestos' proprietary RPT Rust Prevention Technology. Engineered to combat the increasing exposure that modern open-wheel vehicle designs place on brake components, this rotor is built to withstand rain, road salt, snow, and harsh road chemicals that accelerate corrosion on uncoated surfaces.

Each rotor is developed from OE samples and manufactured with G3000-qualified iron, ensuring precise form, fit, and function that meets or exceeds original equipment specifications. The entire rotor surface — including the cooling vanes — is treated with a full Grey Fusion 4.0™ coating to provide long-lasting rust protection and delay rust-induced braking performance issues.

Key Features:

• Full Grey Fusion 4.0™ coating applied to the entire rotor surface, including cooling vanes, for maximum corrosion resistance
• G3000-qualified material developed from OE samples for guaranteed form, fit, and function
• Lateral runout of 0.0004" or less and thickness variation under 0.0005" to minimize pedal pulsation and brake noise
• Mill balanced edges — 100% validated to minimize thickness variation, reduce vibration, and promote quieter stopping
• Sold as 1 rotor per pack
