Centric 320.50012F Disc Brake Rotor - Front

Centric GCX Front Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor - Full Coating, part number 320.50012F, is a front vented rotor built to match OE performance while adding corrosion resistance on non-mating surfaces. It is a direct-fit option for 2004-2009 Kia Spectra and 2005-2009 Kia Spectra5 front brake service.

With a fully coated disc finish, coated hat, smooth surface, and Centric RS200 protection, this rotor is built for drivers who want a replacement brake rotor that maintains a clean appearance and resists rust on exposed areas. The 320.50012F also uses application-specific metallurgy to align with the OEM-style rotor profile for the vehicle.

Detailed Description

Centric GCX Elemental Protection Disc Brake Rotors are engineered for OE-style fit and performance with added protection on exposed surfaces. This rotor uses Centric’s advanced RS200 coating on non-mating areas to help reduce rust and corrosion, while the smooth braking surface remains ready for pad contact. The GCX line also uses application-specific coating patterns and metallurgy to better match the brake pad friction type and the OEM rotor profile.

For front brake replacement on 2004-2009 Kia Spectra and 2005-2009 Kia Spectra5, the 320.50012F provides the dimensions and mounting layout needed for a proper service replacement. The rotor measures 47.800 mm in overall height, 69.000 mm center hole diameter, and 114.300 mm bolt circle diameter, with 4 stud/lug holes and a floating center mounting design.

What This Rotor Helps Address

• Front brake pulsation caused by worn or uneven rotors
• Rust buildup on exposed rotor surfaces
• Brake noise related to rotor wear or surface condition
• Reduced braking consistency from thin or heat-worn rotors
• OE replacement needs for Kia Spectra and Kia Spectra5 front brake service

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and brake pad condition before installation. Clean the hub mounting surface thoroughly to help prevent runout-related issues, and inspect calipers, slides, and pads during rotor replacement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Fits 2004-2009 Kia Spectra, front. Fits 2005-2009 Kia Spectra5, front. Part number 320.50012F is a direct-fit front rotor for these applications.

Quality Assurance

Centric designs the GCX rotor line to match OE performance targets and uses metallurgical formulations selected to align with the vehicle’s OEM rotor profile. The fully coated finish and RS200 protection are intended to improve corrosion resistance on non-mating surfaces over the service life of the rotor.
