Product Details

Centric GCX Elemental Protection Disc Brake Rotors are built for front axle brake service on vehicles such as the Mitsubishi Diamante, Mitsubishi Eclipse, Mitsubishi Galant, Mitsubishi 3000GT, Dodge Stealth, and Plymouth Laser. The fully coated construction helps protect the rotor’s disc and hat surfaces from corrosion, while the vented, straight-vane design supports heat management during repeated stops. This rotor is a direct-fit style replacement for applications that require the listed dimensions and mounting pattern, including Fits 1992-2004 Mitsubishi Diamante, front and Fits 1993-2000 Mitsubishi Eclipse, front.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Rotor Helps Address

• Brake pulsation caused by worn or uneven rotor surfaces
• Corrosion on exposed rotor and hat surfaces
• Reduced braking consistency from heat buildup in front brake service
• Noise or vibration related to rotor wear beyond discard thickness
• Fitment issues when replacing a front rotor with the correct bolt pattern and center bore

Installation Notes and Tips

Verify rotor dimensions, hub center bore, lug pattern, and overall height before installation. Confirm front axle fitment for your exact vehicle year and build date, especially for the 2000 Mitsubishi Galant, front, which is listed with a to 5/00 note, and the 1992 Mitsubishi Eclipse, front, which is listed with a from 6/92 note. Inspect pads, calipers, and hub surfaces during service to help ensure even rotor contact and proper brake operation. Fits 1991-1999 Mitsubishi 3000GT, front; Fits 1991-1996 Dodge Stealth, front; Fits 1993-1994 Plymouth Laser, front; Fits 1999 Mitsubishi Galant, front; Fits 2000 Mitsubishi Galant, front.

Quality Assurance
