Purpose and compatibility with BMW E81, E87, E90, E92

The presented set of discs is intended for the rear axle, left and right side of the vehicle, which facilitates the simultaneous replacement of both elements and maintains even operation of the braking system. The design and dimensions correspond to the solutions used in popular BMW 1 and 3 series E-generation models, which allows for maintaining factory braking characteristics without the need to modify calipers or hubs. As a result, installation is predictable and the risk of fitment issues is limited.

Technical characteristics of the brake disc set

The set includes two discs with a diameter of 296 mm and a nominal thickness of 10.5 mm, which corresponds to the typical configuration of the rear braking system in many versions of the BMW E81, E87, E90, and E92. This dimension provides an adequate friction surface for the pads, stable heat dissipation, and proper cooperation with the vehicle's safety systems. Replacing both discs on the axle simultaneously allows for maintaining even pad wear and predictable vehicle behavior during emergency braking.

As an element in the Brake discs category, the product plays a key role in transferring braking force from the caliper to the wheel. The properly selected diameter and thickness of the disc affect:

• thermal stability during repetitive braking,
• even wear of the working surface,
• proper cooperation with pads featuring a standard friction compound.

Condition, origin, and compatibility verification

The offered set consists of used brake discs, which means that before installation, their current condition should be verified in terms of thickness, potential ridges, axial runout, and evenness of the working surface. Such elements are often chosen as an interim solution or for vehicles operated in less demanding conditions, where the priority is to reduce costs while maintaining system functionality.

The product has an assigned OEM part number and a set of interchangeable numbers, which facilitates matching to a specific engine and equipment version of the BMW. Before purchasing, it is worth comparing the markings with the vehicle documentation or existing elements to confirm full dimensional and structural compatibility.

Benefits of using a complete rear set

Using a complete set for the rear axle brings a number of practical benefits:

• consistent friction parameters on both sides of the axle,
• easier control and maintenance of the braking system in the future,
• the possibility of simultaneously assessing the condition of pads, calipers, and lines during a single disassembly.

For users considering a broader system upgrade, such a set can be part of a larger service package that also includes pads, flexible lines, or brake fluid. Due to the maintenance of factory disc dimensions, there is no need to interfere with other system components.

Expert support and selection of used brake components

When choosing used braking system components, it is worth being guided not only by price but also by the procedure for verifying condition and compatibility. Detailed tips on how to safely select discs, calipers, and ABS system elements can be found in the article: Second-hand braking system: how to safely select discs, calipers, and ABS?. This is a practical checklist that helps reduce the risk of an unsuccessful purchase and facilitates the assessment of the real utility of used parts.
