Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented design to promote airflow and reduce heat buildup during braking. The rotor features a plain disc finish combined with a zinc silver coated hat to resist rust and corrosion, extending the rotor's service life. The drilled and slotted surface pattern helps to evacuate brake dust, gases, and water, improving braking response and reducing the risk of brake fade under demanding conditions.

With a nominal thickness of 16 mm and a discard thickness of 14 mm, this rotor maintains structural integrity and safety throughout its lifespan. The 5-bolt hole configuration with a 114.3 mm bolt circle diameter ensures compatibility with a range of INFINITI and Nissan models, including the FX35, FX37, FX45, JX35, M35h, M37, M56, Murano, Pathfinder, Q50, Q60, Q70, Q70L, Quest, QX60, and QX70.
