Centric 320.35052H Disc Brake Rotor - Front

Centric GCX Front Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor is a front vented rotor built for Mercedes-Benz applications that call for a 345 mm disc and OE-style braking performance. Part number 320.35052H uses a fully coated finish and high-carbon metallurgy to help resist rust while maintaining a clean appearance over time.

Designed for front axle use on select Mercedes-Benz C-Class and CLK/SLK AMG models, this rotor is a direct-fit replacement for drivers looking for a smooth, vented disc with application-specific coating and OE-matched dimensions.

Key Features

• Part number 320.35052H
• Fully coated disc finish with coated hat for corrosion resistance on non-mating surfaces
• Vented rotor design with curved vanes for front brake cooling
• High-carbon rotor metallurgy for OE-style material matching
• Smooth surface type for consistent pad contact
• 345 mm outside diameter, 30.0 mm nominal thickness
• 5-lug pattern with 112 mm bolt circle diameter
• Floating disc mounting and 67 mm center hole diameter

Product Line Details

Centric GCX Elemental Protection Disc Brake Rotors are engineered with application-specific coating patterns and metallurgy choices that align with brake pad friction type and OEM material profiles. The GCX line uses Centric’s RS200 finish on non-mating surfaces to help protect against rust and corrosion while preserving rotor appearance during service life.

Detailed Description

This Centric GCX rotor is built to match OE dimensions and braking characteristics for front axle service on Mercedes-Benz performance models. The rotor measures 13.583 inches in outside diameter, 1.181 inches nominal thickness, and 1.079 inches discard thickness, with a 1.870-inch overall height. It also features a curved vane layout for heat management and a fully coated finish for added surface protection. Part number 320.35052H is a practical choice when replacing worn front rotors on vehicles that require a 345 mm vented disc.

Compatible With select Mercedes-Benz applications including the C32 AMG, C55 AMG, CLK500, CLK550, CLK55 AMG, C350 with AMG Performance Brakes, and SLK55 AMG. This part number, 320.35052H, is also a fitment-specific option for front brake service on these models.

What It Helps Address

• Brake rotor wear that can lead to reduced stopping consistency
• Surface rust and corrosion on exposed rotor areas
• Brake pulsation caused by rotor thickness loss or uneven wear
• Heat buildup during repeated front brake use
• Loss of OE-style fitment after rotor replacement
