Detailed Product Description

The Beck Arnley 083-3039 disc brake rotor is a vented rotor designed to optimize braking efficiency for BMW luxury sedans including the 745i, 745Li, 750i, 750Li, 760i, and 760Li. Its vented construction allows air to flow between the rotor surfaces, reducing heat buildup during braking and minimizing the risk of brake fade. The rotor features a 5-lug bolt pattern with a 120 mm bolt circle diameter, ensuring a secure fit on compatible BMW hubs. With an outer diameter of 347.8 mm and a rotor thickness of 30 mm, this rotor meets OEM specifications for size and performance. The rotor center hole diameter of 79 mm and lug stud hole inner diameter of 16.7 mm provide precise alignment and mounting stability. The minimum thickness of 28.4 mm is critical for maintaining structural integrity and safe braking performance over time.
