Product Details

Centric’s GCX rotor line is application-specific, using coating patterns and metallurgy selected to align with OE brake pad friction characteristics and vehicle requirements. This rotor uses Centric’s RS200 coating on non-mating surfaces to help protect against rust and corrosion, while the vented straight-vane construction supports heat management during repeated stops. The result is a front disc brake rotor built for Chevrolet Astro and GMC Safari owners who want a direct-fit replacement with corrosion protection and OE-oriented performance. Part number 320.66016F is also identified by Centric GCX Elemental Protection Disc Brake Rotors - Full Coating naming.

What This Rotor Helps Address

• Rust buildup on exposed rotor surfaces
• Brake pulsation caused by worn or uneven rotor surfaces
• Reduced braking consistency from rotor wear
• Noise or vibration related to rotor condition
• Front brake service needs on Astro and Safari models

Installation Notes and Tips

Verify rotor dimensions, hub bore, bolt circle, and ABS tone ring requirements before installation. Clean the hub mounting surface thoroughly so the rotor seats flat, and inspect pads, calipers, and hardware condition at the same time. For best results, follow the vehicle manufacturer’s brake bedding procedure after installation.

Fits 1990-2002 Chevrolet Astro, front. Fits 1990-2002 GMC Safari, front.

Quality Assurance

Centric designs the GCX rotor line to match OE performance targets and vehicle-specific metallurgy profiles. The fully coated finish is intended to provide added protection on non-mating surfaces for longer-lasting appearance and corrosion resistance.
