The floating disc mounting style allows for slight movement to accommodate thermal expansion and improve braking consistency. The rotor’s dimensions, including a 12.583 inch outside diameter and 5 lug holes on a 4.5 inch bolt circle, are engineered for compatibility with specific INFINITI and Nissan models such as the FX35, Maxima, Murano, and QX70.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor thickness below manufacturer discard limits
• Improving braking performance on INFINITI and Nissan vehicles with OEM-compatible parts
• Resolving uneven brake pad wear due to rotor surface imperfections
• Upgrading to vented rotors for better heat management in daily driving conditions

Installation Notes and Tips

• Verify rotor dimensions and bolt pattern compatibility with your vehicle before installation
• Ensure hub surface is clean and free of rust to prevent rotor runout
