Purpose and function of the set

The presented set includes the steering knuckle, shock absorber, brake caliper, and brake disc for the front axle on the left side in the BMW 1 Series E88 Cabrio model with the N47 engine. This system is responsible for transferring loads from the wheel to the body, guiding the wheel in turns, and effectively reducing speed during braking.

Combining load-bearing and braking elements into one assembly facilitates diagnostics and replacement, especially after a collision or in the case of advanced operational wear. Using components sourced from BMW promotes the maintenance of proper suspension geometry and correct cooperation with safety systems.

Construction and key elements

The steering knuckle acts as a rigid load-bearing element to which the shock absorber, brake caliper, and brake disc are attached. This construction ensures proper wheel guidance, the transfer of lateral and longitudinal forces, and a stable base for the braking system.

The shock absorber is responsible for damping vibrations and controlling wheel movement relative to the body, which translates into confident vehicle handling and predictable behavior in corners. The brake caliper working with the disc ensures even pressure of the brake pads, and thus repeatable braking performance in typical road conditions.

Benefits of using a complete module

• A coherent set of elements from one axle – easier identification and matching to a specific version of the BMW E88 Cabrio 118d N47.
• Factory construction of the steering knuckle and shock absorber – maintenance of the correct suspension geometry on the left side.
• Brake components matched to the vehicle's system – predictable braking characteristics.
• A solution conducive to post-accident service – the possibility of replacing the entire module instead of individual elements.
• Specific placement on the vehicle – minimization of the risk of error when selecting parts.

Condition, origin, and technical aspects

The set comes from a BMW vehicle and is offered as a used item, which allows for economical repair while maintaining the original construction. The product has assigned OEM part numbers and interchangeable numbers, which facilitates the verification of compatibility with a specific car configuration. The specified weight of the assembly confirms that it is a full load-bearing and braking module, not a single detail.

Thanks to the clear indication of the placement on the vehicle, one can precisely select the mounting side and avoid problems during installation. This type of set is particularly useful for suspension and brake repairs after mechanical damage or when replacing elements with a significant degree of wear.
