Detailed Product Description

This Raybestos disc brake rotor, part number 982271, is a conventional vented rotor designed to meet the braking demands of various BMW models including the 535i and 640i series. The vented design enhances airflow between rotor surfaces, reducing heat buildup during braking and helping to maintain consistent performance under street driving conditions. The coated rotor surface provides a protective layer against rust and corrosion, which is especially beneficial for vehicles exposed to moisture and road salts.

With a nominal thickness of 1.181 inches (30.000 mm) and a discard thickness of 1.118 inches (28.400 mm), this rotor ensures durability and safety by indicating when replacement is necessary. The rotor’s overall height of 2.602 inches (66.100 mm) and outside diameter of 13.701 inches (348.000 mm) are engineered to fit precisely with the specified BMW models. The five mounting bolt holes with a 120.000 mm bolt circle diameter and 0.654 inch (16.600 mm) diameter ensure secure installation.
