Product Details

Built for the front left position on the Lexus GS350, this Centric rotor uses a vented construction and curved vanes to support heat management during braking. The fully coated disc finish and coated hat finish help protect exposed surfaces, while the smooth braking surface supports even pad contact. The 2.441 in. center hole diameter, 5 lug holes, and 114.300 mm bolt circle align with the listed vehicle application. The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on corrosion-resistant surface treatment for drivers who want a direct-fit rotor with a finished appearance.

Part number 320.44154F is also a fitment-specific search term for 2007-2011 Lexus GS350 front left brake rotor replacement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Reasons for Replacement

• Brake pulsation from rotor wear or thickness variation
• Visible corrosion on the rotor hat or braking surface
• Reduced braking smoothness from uneven pad contact
• Rotor scoring, heat checking, or surface damage
• Service replacement for a worn front left brake rotor

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and wheel clearance before installation. Clean the hub mounting surface thoroughly so the rotor seats flat, and inspect brake pads and caliper hardware for wear before reassembly. Confirm this rotor is for the front left position on the 2007-2011 Lexus GS350. Part number 320.44154F should be matched to the vehicle’s brake system specifications before installation.

Quality Assurance

Centric GCX rotors are built around application-specific dimensions and coated surfaces for consistent fitment and corrosion protection. This rotor is manufactured to match the listed GS350 front left application and dimensional requirements.
