Centric GCX Front Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.35023H, is a front vented rotor built for Mercedes-Benz applications that need OE-style braking performance and corrosion resistance. Its fully coated finish helps protect non-mating surfaces from rust while maintaining a clean appearance over time.

Compatible With 1992-1999 Mercedes-Benz S-Class and coupe models, this rotor is engineered for direct-fit front brake service on select CL500, CL600, S320, S420, S500, S600, S350, 300SD, 300SE, 400SE, 400SEL, 500SEC, 500SEL, and 600SEC applications.

Key Features

• Part number 320.35023H
• Fully coated disc finish and coated hat for added rust protection
• Vented rotor design with smooth surface type
• High-carbon metallurgy matched to OEM-style rotor requirements
• Curved vane construction for heat management
• 5-lug pattern with 112 mm bolt circle and 67 mm center hole
• Front axle application for select Mercedes-Benz models

Centric GCX Elemental Protection Line

The GCX Elemental Protection line is built around application-specific coating patterns and rotor metallurgy. Centric uses RS200 coating on non-mating surfaces and offers rotor formulations that align with OEM carbon content profiles, helping maintain consistent braking feel and long-term surface protection. For buyers searching for a Mercedes-Benz front brake rotor with coated surfaces and OE-style fitment, the GCX line is a focused replacement option.

Detailed Description

This Centric brake rotor is designed for front disc brake service on 1992-1999 Mercedes-Benz vehicles, including S-Class sedans and select CL coupes. The rotor measures 320 mm outside diameter, 30 mm nominal thickness, 27.4 mm discard thickness, and 82 mm overall height. It uses a floating disc mounting design, curved vanes, and a smooth friction surface to support stable braking performance.

Part number 320.35023H is a practical choice for Mercedes-Benz S320 front brake rotor replacement, Mercedes-Benz S500 front rotor service, and Mercedes-Benz CL500 front brake rotor applications where coated corrosion protection and OE-style dimensions matter.

What This Rotor Helps Address

• Rust buildup on exposed rotor surfaces
• Brake pulsation caused by worn or below-spec rotors
• Reduced braking consistency from heat-stressed front rotors
• Uneven appearance from uncoated replacement rotors
• Front brake service needs on select Mercedes-Benz models

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and caliper clearance before installation. This rotor is for front position use only and does not include ABS tone ring or bearings. Clean the hub mounting surface thoroughly, inspect pads and calipers for wear, and follow the vehicle manufacturer’s torque specifications during assembly.
