StopTech 320.33090 Centric GCX Brake Rotor with Partial GEOMET Coating

The StopTech Centric GCX 320.33090 is a premium replacement brake rotor engineered to restore original equipment (OE) braking performance while delivering superior corrosion resistance and extended service life. Featuring StopTech's advanced Elemental Protection GEOMET coating, this rotor is road-ready straight out of the box — no break-in prep required.

Key Features:

• Partial GEOMET Coating on Friction Surfaces: Strategically applied coating promotes up to 10% faster pad bed-in while eliminating unsightly corrosion rings that form on bare-metal rotors
• Full GEOMET Coating on All Non-Mating Surfaces: Complete coverage on hats, vanes, and non-friction areas provides long-lasting rust and corrosion resistance, even in harsh environments
• Double Disc Ground Braking Surface: Precision machining ensures parallelism, eliminates runout, and delivers near-perfect disc thickness variation (DTV) for smooth, vibration-free braking
• Non-Directional Friction Surface Finish: Double disc grinding produces a non-directional finish that promotes more effective and even pad-rotor break-in
• OE-Style Vane Design: Engineered to match original equipment vane geometry for optimal rotor cooling and thermal performance
• Fully Machined Non-Friction Surfaces: Improves rotor balance and eliminates vibration for a smoother, quieter ride
• OE Metallurgical Profile Matching: Formulated using G11H18 Enhanced Carbon or G12H17 High Carbon alloys to match each vehicle's original equipment metallurgical specification

The Centric GCX rotor is designed as a direct, no-hassle replacement that installs without additional preparation. Its combination of partial and full GEOMET coating patterns is application-specific, matched to complement the brake pad friction type for optimal performance and longevity.
