Centric 320.66036F GCX Plain 1-Piece Rear Brake Rotor with Full Coating

The Centric 320.66036F GCX rear brake rotor is engineered to restore original equipment performance while delivering superior corrosion protection and extended service life. This plain-style, 1-piece rotor features advanced coating technology designed to keep your braking system performing at its best in all conditions.

Advanced Protection Technology:

• Full RS200 coating on all non-mating surfaces provides elemental-level protection against rust and corrosion
• GEOMET coating on friction surfaces eliminates corrosion rings and promotes 10% faster brake pad bed-in
• Road-ready design requires no additional prep work—install straight from the box
• Application-specific coating pattern matches OE brake pad friction type for optimal performance

Precision Engineering:

• Double disc ground surface eliminates disc thickness variation (DTV) issues for smooth, vibration-free braking
• OE-style vane design maintains proper cooling and heat dissipation
• Premium metallurgy using G11H18 Enhanced Carbon or G12H17 High Carbon alloys matched to OEM specifications
• Fully machined surfaces restore factory appearance and balance

Centric GCX rotors are developed by Centric's in-house engineering team to match factory fitments while providing professional-grade durability. The full coating coverage ensures long-lasting corrosion resistance and maintains attractive appearance throughout the rotor's service life, making this an excellent direct replacement for your original rear brake rotor.
