• Minimum rotor thickness of 18.4 mm to ensure durability

Detailed Product Description

The Beck Arnley 083-3659 disc brake rotor features a vented construction that enhances airflow between the rotor surfaces, reducing heat buildup and minimizing brake fade. With a 5-lug configuration and a 120 mm bolt pattern, this rotor is specifically designed to match the BMW 128i's wheel mounting system. The rotor measures 300 mm in outer diameter and 20 mm in surface thickness, providing a solid braking surface that meets OEM specifications. The rotor hub outer diameter is 164 mm, and the rotor height is 76 mm, ensuring proper alignment and fitment. The rotor center hole diameter of 75 mm allows for a secure fit on the vehicle hub, while the lug stud hole inner diameter of 14.7 mm accommodates the lug studs precisely. This rotor is not solid but vented, which is critical for maintaining brake system efficiency under demanding conditions.
