Intended Use and Fitment for BMW E81 E87 LCI

The presented wheel has been designed as a component of the rear suspension for facelifted BMW 1 Series E81/E87 generation vehicles. By maintaining factory dimensions and geometric parameters, it ensures proper vehicle handling, correct operation of the running gear, and a cohesive appearance with other body elements. It is a practical choice for replacing a damaged rim or restoring a car to its original factory configuration.

Aluminum Construction and Geometric Parameters

The wheel is made of aluminum, which allows for a reduction in unsprung mass compared to steel rims. The lighter construction contributes to better suspension response, improved ride comfort, and can positively influence steering precision. The applied diameter, width, offset, bolt pattern, and center bore diameter have been selected according to BMW's requirements for the rear axle, facilitating installation and compatibility with factory brake system components and hubs.

Mounting Parameters and Compatibility

This wheel belongs to the Wheels category and is designed for five-bolt mounting with the standard BMW bolt pattern. The appropriately selected hole diameter and offset allow for correct seating of the rim relative to the hub and wheel arch, without the need for spacers or suspension modifications. This makes the component suitable for use both as a replacement for a damaged wheel and for assembling a set of wheels with uniform technical specifications.

Performance Characteristics of the Alloy Wheel

The aluminum construction of the wheel promotes efficient heat dissipation from the braking system, which is important during dynamic driving. Simultaneously, the rim provides stable tire support, translating to predictable car behavior in corners and during braking. The used nature of the product means the wheel may show signs of wear, but when correctly selected and installed, it remains a fully functional component of the running gear.

How to Consciously Buy Used Alloy Wheels

When choosing a used wheel, it is worth paying attention to the compatibility of parameters with the vehicle manufacturer's recommendations, the condition of the working surfaces, and any history of refurbishment. Periodic wheel balancing and checking for radial runout after installation are also good practices.
