Centric 320.38015H Disc Brake Rotor - Rear

Centric GCX Rear Brake Rotor Overview

Centric GCX Elemental Protection Disc Brake Rotor 320.38015H is a rear vented rotor built for OE-style braking performance and corrosion resistance. It is a fitment-specific replacement for select Saab 9-5 applications, including 2002-2004 Saab 9-5 rear and 2007-2010 Saab 9-5 rear.

The GCX rotor line uses a full coating on non-mating surfaces and a high-carbon metallurgy profile to match the original equipment specification more closely. For Saab 9-5 rear brake service, this rotor is sized at 299 mm outside diameter with a 20 mm nominal thickness and a smooth surface finish.

Key Features

• Part number 320.38015H
• Rear disc brake rotor for select Saab 9-5 models
• Fully coated disc finish with coated hat for rust and corrosion protection
• Vented rotor design with straight vanes
• High-carbon rotor metallurgy for OE-style thermal characteristics
• 299 mm outside diameter, 20 mm nominal thickness, 18 mm discard thickness
• 5-lug pattern with 110 mm bolt circle and 65.5 mm center hole diameter
• Floating / DIH disc mounting and 2 miscellaneous holes

Product Line Details

Centric GCX Elemental Protection Disc Brake Rotors are engineered around application-specific coating patterns and metallurgy. The RS200 finish is applied to non-mating surfaces to help protect the rotor from rust while preserving the friction surface where the brake pads contact the disc. The GCX line also uses high-carbon alloy formulations selected to align with OEM rotor profiles for the vehicle platform.

Fitment

• Fits 2007-2010 Saab 9-5, rear. Notes: 299mm rear disc; 308mm front disc.
• Fits 2002-2004 Saab 9-5, rear. Notes: vented rear disc.

What This Rotor Helps Address

• Rear brake rotor rust on coated and uncoated surfaces
• Brake pulsation caused by worn rotor thickness
• Reduced braking consistency from heat-worn discs
• Noise or rough braking feel from rotor surface wear
• OE replacement needs for Saab 9-5 rear brake service

Installation Notes

Verify rotor diameter, thickness, center hole diameter, and bolt pattern before installation. This rotor is a rear vented design with a smooth surface and 5-lug mounting pattern, so it should be matched to the vehicle’s rear brake configuration exactly as listed. Clean the hub face before mounting and follow the vehicle manufacturer’s torque specifications during brake service.

Quality Assurance

Centric GCX rotors are built to match OE performance targets and use corrosion-resistant coating on non-mating surfaces for extended service life and improved appearance. Centric states coverage for more than 98% of vehicles on the road through a broad rotor catalog, including this 320.38015H application.
