Purpose and fitment for BMW 3 E90/E91/E92

The presented set includes two rear brake discs intended for installation on the right and left side of the rear axle in BMW 3 Series E90, E91, and E92 generations. The use of the specific 336x22 mm working dimension ensures proper cooperation with the calipers and pads factory-fitted for this brake system configuration, which translates into stable braking performance and correct operation of assistance systems such as ABS or traction control.

Ventilated design and performance characteristics

The ventilated structure of the discs ensures more efficient heat dissipation from the working surface during intensive braking. This reduces overheating and lowers the risk of brake fade during repetitive, heavy braking. The set is designed as a rear axle component, which means optimal working thickness and diameter matched to the stock calipers used in the BMW 3 E90/E91/E92 with this type of system.

Installation and operational characteristics

The set of rear ventilated discs is prepared for installation in place of the factory components, without the need for modifying mounts or hubs. The placement on the vehicle covers the rear axle on the left and right side, which facilitates part selection during comprehensive brake system maintenance. The used nature of the product allows for an economical replacement while maintaining correct geometry and compatibility with original equipment.

Identification parameters and part number compatibility

The discs have an assigned OEM part number and associated interchangeable numbers, which facilitates verification of compatibility with a specific vehicle configuration. This allows for precise matching to a given BMW 3 Series variant, as well as easier identification in service catalogs and parts selection systems. This information is particularly useful when comparing components with currently installed parts.

Safe selection of used brake system components

When choosing used brake discs, it is worth paying attention to dimension compatibility, construction type (ventilated/solid), and axle designation.
