Detailed Product Description

This Power Stop front disc brake rotor is designed with a vented construction to help dissipate heat more effectively during braking, reducing the risk of brake fade. The rotor features a Geomet coating, a rust-resistant finish that protects the rotor surface from corrosion and extends service life, especially in harsh weather conditions. With a nominal thickness of 31.10 mm and a discard thickness of 27.00 mm, this rotor maintains structural integrity and braking efficiency throughout its lifespan. The 345.10 mm outside diameter and 120.00 mm mounting bolt hole circle diameter with 6 lug holes ensure a precise fit for the front brakes of Buick Enclave, Cadillac XT5, and XT6 models.
