Product Line Details: Centric Premium High Carbon Alloy Disc Brake Rotors

The Centric Premium High Carbon Alloy Disc Brake Rotors line focuses on high carbon alloy construction to enhance rotor strength and heat dissipation. This product line is designed to provide improved wear resistance and reduced brake fade compared to standard rotors. The 125.35149 rotor benefits from this advanced metallurgy, making it suitable for the braking demands of Infiniti and Mercedes-Benz vehicles requiring precise and consistent rotor performance.

Technical Description and Specifications

This Centric rotor features a solid disc design with a smooth surface type, optimized for standard braking applications. The rotor’s nominal thickness is 10.0 mm, with a discard thickness of 8.3 mm, ensuring a clear service life indicator for replacement. The hat is coated to resist corrosion, extending the rotor’s durability in various driving conditions. The rotor mounts using a 5-bolt pattern with a 112 mm bolt circle diameter and a center hole diameter of 67.1 mm, matching OEM fitment requirements. The floating disc mounting design allows for slight movement to reduce stress and improve braking consistency.

Applications and Problem Solving
