Intended Use and BMW Fitment

This component belongs to the Suspension Replacement Kits category and is designed for installation on the front left side of BMW 1 Series E87 models with the N45 engine. Integrating the shock absorber with the hub assembly into a single unit simplifies servicing, reduces workshop time, and minimizes the risk of installation errors, which is particularly important for BMW's precise suspension systems.

Original BMW sourcing ensures adherence to factory geometry, correct mounting points, and compatibility with standard drivetrain components such as control arms, wheel hubs, and the braking system. This allows for straightforward wheel alignment and restoration of proper handling parameters after replacement.

Sport Suspension Characteristics

The SPORT version features stiffer damping compared to standard comfort suspension. This translates to:

• more direct body response to steering inputs,
• reduced body roll in corners,
• improved stability during dynamic driving,
• more precise trajectory maintenance during braking and acceleration.

For drivers who value sporty handling in their BMW E87, this complete shock absorber and hub assembly is a sensible choice when replacing worn components or restoring the original specification of a sport-tuned suspension version.

Condition, Origin, and Benefits of Used Parts

The component is offered in used condition, allowing for significant cost savings compared to new parts while maintaining the original BMW construction. For many users, this represents a reasonable compromise between price and quality – especially for suspension assemblies where compatibility with factory parameters and correct geometry are crucial.

An additional advantage is the presence of the original OEM part number and the availability of interchangeable numbers (visible in the technical specifications), which simplifies compatibility verification with specific body types, model years, and equipment configurations. This allows workshops or users to quickly confirm that the assembly is suitable for a particular BMW E87 model.

Practical Aspects of Installation and Operation

Its placement on the vehicle as front – left side means the component directly interacts with the steering and braking systems, playing a crucial role in driving safety. Replacing the complete assembly (shock absorber + hub) is often more convenient than refurbishing individual components because it:

• simplifies the disassembly and assembly process,
• reduces the risk of damaging sockets, bolts, and mounts,
• facilitates subsequent suspension geometry alignment,
• ensures consistent performance of the entire unit during operation.

After installation, a full wheel alignment is recommended to fully utilize the sporty characteristics of the suspension and ensure even tire wear.
