Centric 320.33107H Disc Brake Rotor - Front

Centric GCX Front Brake Rotor for Audi

Centric GCX Elemental Protection Disc Brake Rotor 320.33107H is built for front brake service on select Audi A4, A4 Quattro, A6, A6 Quattro, A8, and A8 Quattro applications. It combines a fully coated finish with high-carbon metallurgy to match OE-style braking performance while helping resist rust on exposed surfaces.

The GCX Elemental Protection line uses Centric’s RS200 coating on non-mating surfaces and application-specific coating patterns to work with the brake pad friction type. For Audi A4 Quattro and Audi A6 front brake replacement, this rotor is sized for a 312 mm front disc application and is engineered to align with the vehicle’s original metallurgy profile.

Product Details

Centric’s GCX Elemental Protection Disc Brake Rotors are engineered to match original equipment performance while adding protection against rust and corrosion on exposed areas. This rotor uses a fully coated disc finish and coated hat, which helps maintain appearance and surface protection over time. The high-carbon construction supports consistent braking behavior and is selected to mirror the OEM metallurgical profile used on the covered Audi applications.

What This Rotor Helps Address

• Front brake rotor rust on exposed surfaces
• Brake pulsation caused by worn or uneven rotors
• Reduced braking consistency from heat-stressed rotor surfaces
• Noise or vibration associated with rotor wear
• Replacement needs for Audi A4, A4 Quattro, A6, A6 Quattro, A8, and A8 Quattro front brake service

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and brake pad condition before installation. Clean the rotor’s friction surfaces before use to remove any protective residue, and inspect calipers, slides, and hardware for wear that could affect braking performance. This rotor is a front application and should be matched to the vehicle’s original brake setup, including the 312 mm front disc configuration where specified.

Quality Assurance

Centric designs the GCX line to align with OE performance targets and uses application-specific coating patterns plus high-carbon metallurgy for consistent fit and finish. Part number 320.33107H is part of Centric’s broader GCX coverage for late-model and earlier Audi brake applications.
