StopTech 32046074F GCX Plain 1-Piece Rear Brake Rotor with Elemental Protection

The StopTech 32046074F GCX Plain Rear Brake Rotor is a premium 1-piece direct-fit replacement disc engineered to restore original equipment braking performance while delivering superior long-term corrosion resistance. Part of the StopTech GCX line — developed by Centric Parts, StopTech's parent company — this rotor is purpose-built to match factory specifications and deliver reliable, quiet stopping power right out of the box.

Elemental Protection GEOMET Coating:

• Partial GEOMET coating applied to the friction surface accelerates pad bed-in by up to 10 percent while eliminating unsightly corrosion rings
• Full GEOMET Elemental Protection coating on all non-mating surfaces inhibits rust formation and provides long-lasting corrosion resistance
• Road-ready finish — no additional prep, cleaning, or break-in treatment required before installation

Precision Engineering:

• Double disc ground friction surface eliminates lateral run-out and disc thickness variation (DTV), ensuring smooth, vibration-free braking
• OE-style vane design promotes efficient heat dissipation and uniform cooling
• Fully machined non-friction surfaces improve rotor balance and reduce vibration
• Application-specific coating pattern matched to the correct OE brake pad friction type for your vehicle

Advanced Metallurgy:

• Formulated using G11H18 Enhanced Carbon or G12H17 High Carbon alloys to precisely match each vehicle's OEM metallurgical profile
• Proprietary Molybdenum and Chromium alloys resist cracking under high-heat conditions and improve braking power
• Symmetric vane and split-core casting design ensures uniform heat distribution across the rotor face

The StopTech GCX line covers both domestic and import passenger cars and light trucks, offering a direct OE-quality replacement with enhanced durability and corrosion protection that outlasts standard uncoated rotors.
