Purpose and compatibility with the BMW 3 Series

The presented disc belongs to the Brake discs category and was designed specifically for BMW 3 Series E90 LCI and F30 models. The design is intended for operation on the rear axle, with the possibility of installation on both the left and right sides, which facilitates the selection of the component during brake system maintenance. Using an original disc allows for maintaining the factory braking characteristics, appropriate for the suspension and safety systems of BMW.

Technical characteristics of the 300x20 disc

The 300x20 brake disc has been developed for effective heat dissipation and uniform wear of the working surface. The working thickness and diameter are matched to the calipers and pads used in the rear axle of the BMW 3 Series, which promotes stable system operation across a wide range of loads. The proper geometry of the disc supports even pad pressure, reducing the risk of vibrations and brake pedal pulsation when installed correctly and used with properly selected components.

Benefits of using an original, used disc

Choosing an original, used BMW brake disc is a solution that allows you to combine cost control with maintaining the factory specification of the component. The disc comes from a system designed by the vehicle manufacturer, ensuring its parameters are consistent with the design assumptions of the suspension, ABS system, and traction control. For many users, this is a reasonable compromise between price and quality, especially during comprehensive rear axle maintenance, including the replacement of pads and other interacting components.

Installation area: rear, left / right side

The placement of the disc on the rear axle, with the possibility of installation on both sides of the vehicle, simplifies the service process and reduces the risk of errors when selecting parts. In practice, this means that one type of disc can be used on both the driver's and passenger's side, provided that the other brake system components are consistent with the factory configuration. Such a solution promotes faster workshop service and facilitates repair planning for BMW 3 Series E90 LCI and F30 vehicles.

Safety and selection of recycled parts

When servicing the brake system, many users consider using original recycled parts, especially for components such as calipers or discs.
