Detailed Description

Centric GCX Elemental Protection Disc Brake Rotors are built for drivers who want a direct-fit front rotor with corrosion protection on the disc and hat surfaces. The vented construction and straight vane design help manage heat during repeated stops, while the smooth braking surface supports even pad contact. For Acura RDX front brake service from 2013-2018 and 2016 Acura ILX front brake replacement, part number 320.40080F provides the dimensions and mounting layout needed for a proper OE-style rotor swap.

This rotor measures 311.8 mm in outside diameter, 47.2 mm in overall height, and uses a floating disc mounting layout with four miscellaneous holes and no ABS tone ring. The coated finish is intended to help reduce visible corrosion on exposed rotor surfaces, making it a practical choice for front brake maintenance on Acura RDX and Acura ILX models.

What It Helps Address

• Front brake rotor wear and thickness loss
• Brake pulsation caused by rotor surface condition
• Rust buildup on exposed rotor and hat surfaces
• Heat-related braking inconsistency during repeated stops
• OE rotor replacement needs for Acura RDX and Acura ILX front brake service

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and lug pattern before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake noise or pedal vibration. Replace brake pads as needed and follow the vehicle manufacturer’s torque specifications during wheel installation. Part number 320.40080F is a front rotor only and should be matched to the confirmed Acura RDX or Acura ILX front application listed above.

Quality Assurance

Centric’s GCX Elemental Protection line uses coated rotor surfaces and protected hat areas to support corrosion resistance in everyday brake service. This rotor is built to the listed specifications for direct replacement use on the confirmed Acura applications.
