Centric 320.50031H GCX Plain 1-Piece Rear Brake Rotor

The Centric 320.50031H GCX Plain 1-Piece Rear Brake Rotor is engineered to restore OE performance while providing superior protection against rust and corrosion. This premium brake rotor features Centric's advanced RS200 zinc-aluminum coating on all non-mating surfaces, delivering over 200 hours of salt spray corrosion resistance for extended service life even in harsh environments.

Manufactured with carbon-enhanced advanced metallurgy (G11H18 Enhanced Carbon or G12H17 High Carbon alloy), this rotor is designed to match OEM metallurgical profiles for optimal heat transfer and structural strength. The double disc ground braking surface ensures parallelism, eliminates runout, and provides near-perfect disc thickness variation (DTV) for smooth, vibration-free stopping from the first brake application. The precision machining creates a non-directional finish that promotes effective pad-rotor break-in and consistent braking performance.

Key Features:

• RS200 zinc-aluminum rich coating for superior corrosion protection
• Carbon-enhanced metallurgy for optimal heat capacity and strength
• Double disc ground surface for precision parallelism and minimal runout
• OE vane design and plate thickness for proper heat dissipation
• Low initial lateral run-out for vibration-free performance
• Road-ready from the box with no additional preparation needed
• 1-piece plain rotor design for rear brake applications
