The 121.51049 rotor is part of this line, offering vented construction to help reduce heat buildup during braking on the Genesis G90.

Detailed Product Description

This Centric disc brake rotor features a vented design that enhances airflow between the rotor surfaces, helping to dissipate heat generated during braking. The smooth surface type ensures even pad wear and quiet operation. With an overall height of 2.433 inches (61.8 mm) and a mounting bolt hole circle diameter of 4.5 inches (114.3 mm), it is engineered for precise fitment on the Genesis G90. The rotor’s floating disc mounting and three miscellaneous holes contribute to proper alignment and secure installation. Note that this rotor does not include an ABS tone ring or bearings, so those components must be sourced separately if required.
