Purpose and compatibility with BMW models

The presented set of rear brake discs has been developed for BMW E84, E87 LCI, E90, E91, and E93 platforms, which translates into a precise fit for the hub, caliper, and brake system shields. The disc design complies with the manufacturer's factory standards, ensuring that the proper geometry of the system is maintained, as well as correct interaction with stock brake pads. The placement on the vehicle is limited to the rear axle, which facilitates part selection when planning a replacement in only one area of the braking system. Using an original BMW solution allows for maintaining consistent braking characteristics between the front and rear of the vehicle.

Ventilated design and performance characteristics

The ventilated rear discs in this set are designed to effectively dissipate heat generated during braking. Ventilation channels between the working surfaces support thermal stability, which reduces the risk of braking efficiency loss under prolonged load. This type of construction also promotes even wear of the friction surfaces, which translates into predictable vehicle behavior. For the user, this means more repeatable, linear brake pedal operation and better control over the car in typical road conditions. The design, consistent with BMW's specifications, helps maintain the factory brake force balance, which is particularly important in vehicles equipped with advanced electronic stability control systems.

Product nature and service application

The offered set belongs to the Brake Discs category and is intended for service applications in BMW vehicles where it is necessary to replace worn rear braking system components. The product will perform well both during standard periodic maintenance and during more extensive work related to restoring the full efficiency of the braking system. Due to the factory origin of the solution, the set is particularly attractive to users who want to maintain the original handling and braking characteristics, avoiding random aftermarket replacements with uncertain parameters. Consistency with BMW's design also facilitates work for workshops, shortening assembly time and minimizing the risk of compatibility issues.

Benefits of choosing original brake components

Choosing original BMW rear brake discs primarily ensures predictable vehicle behavior and the certainty that the component was designed for specific models. In practice, this translates into:

• maintaining factory braking characteristics,
• proper cooperation with stock pads and calipers,
• adequate stiffness and resistance to thermal loads,
• easier diagnostics and service in the future.
