Centric 320.62057F Disc Brake Rotor - Front

Centric GCX Front Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.62057F, is built for front brake service on a range of Buick, Pontiac, and Oldsmobile applications. It combines OE-style fitment with a fully coated finish to help resist rust on exposed surfaces while maintaining the braking surface needed for consistent stopping performance.

For drivers searching for a front brake rotor for a 1997-2005 Buick Century, 1997-2003 Pontiac Grand Prix, or 2000-2002 Oldsmobile Intrigue, this Centric GCX rotor is matched to the vehicle’s original brake layout and metallurgy profile.

Key Features

• Part number 320.62057F
• Front disc brake rotor with vented construction
• Fully coated disc finish and coated hat finish for added corrosion resistance
• Smooth surface type for OE-style brake pad contact
• Floating disc mounting with straight vane design
• 5-lug pattern with 118 mm bolt circle and 70.7 mm center hole
• Built to match OE performance and vehicle-specific metallurgy requirements
• Outside diameter: 278 mm; nominal thickness: 32.3 mm; discard thickness: 31.06 mm

Product Line Details

Centric’s GCX Elemental Protection line uses application-specific coating patterns and rotor metallurgy to align with the brake pad friction type and the vehicle’s OEM material profile. The GCX FC full-coating design extends protection to non-mating surfaces, helping the rotor maintain a cleaner appearance and better resistance to rust during everyday use. This approach is especially relevant for front brake rotor replacement on older GM platforms where corrosion protection and OE-style fit are both important.

What This Rotor Helps Address

• Front brake pulsation caused by worn or uneven rotor surfaces
• Rust buildup on exposed rotor areas
• Brake noise related to rotor surface condition
• Reduced braking consistency from rotor wear beyond discard thickness
• Fitment issues when replacing an OE-style vented front rotor

Installation Notes and Tips

Verify rotor dimensions, wheel clearance, and brake configuration before installation. This rotor is for front applications only, and the 2000-2005 Buick LeSabre listing requires 15" wheels. Inspect pads, calipers, and hub surfaces during replacement so the new rotor seats evenly and performs as intended. Part number 320.62057F should be matched to the vehicle’s exact brake setup, including the 1998-1999 Oldsmobile Intrigue JB9 standard brake note where applicable.

Quality Assurance

Centric engineers GCX rotors to align with OE performance targets and vehicle-specific metallurgical requirements. The fully coated finish on non-mating surfaces is designed to provide corrosion protection throughout normal service life, supporting a cleaner rotor appearance and dependable front brake service.
