Detailed Product Description

This Centric disc brake rotor features a vented design with curved vanes that enhance airflow and heat dissipation during braking, reducing the risk of brake fade. The rotor’s nominal thickness of 1.181 inches (30.000 mm) ensures durability and longevity, while the discard thickness of 1.102 inches (28.000 mm) indicates the minimum safe thickness before replacement is necessary. The overall height of 1.996 inches (50.700 mm) and outside diameter of 13.150 inches (334.000 mm) are engineered to match the exact specifications required for Lexus GS350, GS450h, GS460, and IS350 models. The floating disc mounting system and 5 lug holes on a 4.500 inch bolt circle diameter provide secure installation and compatibility with factory hardware. The smooth surface type promotes even pad wear and consistent braking feel.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Resolving excessive brake noise from uneven rotor surfaces
• Improving heat dissipation to prevent brake fade during extended use
• Ensuring proper fitment and compatibility with Lexus GS350, GS450h, GS460, and IS350 brake systems

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets nominal specifications
• Clean rotor surface to remove any protective coatings or debris prior to mounting
• Use proper torque specifications on lug nuts to avoid rotor warping
• Inspect brake pads and replace if worn to maintain optimal braking performance
• Check for compatibility with vehicle’s floating disc mounting system and lug pattern
