Centric 320.33102H Disc Brake Rotor - Rear

Centric GCX Rear Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor is built for OE-style braking performance with added resistance to rust and corrosion. This rear vented rotor uses a fully coated finish on non-mating surfaces and a high-carbon metallurgy profile to match the needs of select Audi A8 Quattro and Volkswagen Phaeton applications.

Part number 320.33102H is engineered for drivers who want a direct-fit rear rotor with a smooth surface, coated hat, and application-specific coating pattern. It is designed for 2004-2010 Audi A8 Quattro rear brake service and 2004-2006 Volkswagen Phaeton rear brake service.

• Part number 320.33102H
• Fully coated disc finish with coated hat for added corrosion protection
• High-carbon rotor metallurgy for OE-matched performance characteristics
• Vented rotor design with straight vanes
• Smooth friction surface
• Floating disc mounting design
• 5-lug pattern with 112.3 mm bolt circle
• Rear application for Audi A8 Quattro and Volkswagen Phaeton

Product Line Details

Centric GCX Elemental Protection Disc Brake Rotors are application-specific rotors built around coating pattern and metallurgy. The GCX line uses Centric’s RS200 finish on non-mating surfaces to help protect exposed areas from rust while maintaining the friction surface needed for braking. The high-carbon construction is selected to align with OEM-style rotor requirements for the vehicle platform.

Detailed Description

This Centric GCX rotor, part number 320.33102H, measures 309.9 mm in outside diameter, 42.2 mm in overall height, and 21.8 mm nominal thickness. Minimum discard thickness is 20.0 mm. The rotor includes a 68.0 mm center hole diameter, 15.3 mm lug hole diameter, and 5 lug holes. It is a vented rear rotor with a vented hat and straight vane style, built for smooth, consistent braking service on the rear axle.

Compatible With 2004-2010 Audi A8 Quattro, rear and 2004-2006 Volkswagen Phaeton, rear. The Centric GCX Elemental Protection Disc Brake Rotor - Full Coating, High Carbon Content is a direct-fit replacement choice for rear brake rotor service where corrosion resistance and OE-style dimensions matter. Part number 320.33102H is also a useful reference when matching the correct rear rotor for these applications.

Common Problems This Rotor Can Address

• Rear rotor rust on exposed surfaces
• Corrosion buildup on the hat and non-mating areas
• Brake pulsation caused by worn or below-spec rotors
• Noisy braking from uneven rotor wear
• Loss of braking consistency from rotor thickness wear

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and rear axle fitment before installation. Clean the hub mounting surface thoroughly so the rotor seats flat, and inspect pads and caliper hardware for wear before reassembly. Because this rotor is fully coated on non-mating surfaces, avoid damaging the coating during handling and installation.

Fits 2004-2010 Audi A8 Quattro, rear. Fits 2004-2006 Volkswagen Phaeton, rear.

Quality Assurance

Centric designs GCX rotors to match OE performance targets while using application-specific coating and metallurgy. The GCX line is built to cover a broad range of vehicle applications, including the Audi A8 Quattro and Volkswagen Phaeton rear brake platforms listed for part number 320.33102H.
