Detailed Product Description

This Centric C-TEK Standard Disc Brake Rotor 121.42111 is a vented rotor featuring a straight vane design that enhances airflow to reduce heat buildup during braking. The rotor’s nominal thickness of 1.181 inches (30.000 mm) ensures structural integrity and longevity, while the discard thickness of 1.122 inches (28.500 mm) indicates the minimum safe thickness before replacement is necessary. With an outside diameter of 13.780 inches (350.000 mm) and an overall height of 1.705 inches (43.300 mm), this rotor is engineered to meet the exact specifications required for INFINITI Armada, QX56, and QX80 models. The floating disc mounting system allows for slight movement to reduce stress and improve braking consistency. The smooth surface type provides even contact with brake pads, minimizing noise and vibration.
