Intended use and compatibility with BMW F30/F31

The presented rim has been prepared as a rear wheel for the BMW 3 Series F30/F31, which ensures the maintenance of proper suspension geometry and compatibility with the manufacturer's factory solutions. As a result, the driver receives a component that works with the vehicle's chassis without the need for additional adapters or modifications.

The rim belongs to the BMW aluminum wheel group, which translates into a favorable strength-to-weight ratio and predictable vehicle behavior during acceleration, braking, and cornering. The applied mounting parameters are consistent with the standard used in this generation of the 3 Series, which facilitates the configuration of a wheel set on the rear axle.

Design characteristics and material

The aluminum construction of the rim ensures good rigidity while reducing unsprung mass, which is important for suspension performance and ride comfort. The rim has been designed for stable seating on the hub and even load distribution, which promotes the durability of the entire wheel assembly.

The black finish gives the rim a subdued, modern look that blends well with both light and dark body colors. This color emphasizes the body lines of the BMW F30/F31 and allows for a more dynamic character of the car without excessive interference with the styling.

Mounting and functional parameters

The rim has been prepared for use on the rear axle, which is important when configuring tire widths and selecting appropriate front/rear sets. The bolt pattern and diameter of the mounting holes are adapted to the BMW standard, which allows for the use of factory bolts and mounting accessories.

In practice, this translates into:

• secure seating of the rim on the hub,
• proper wheel guidance throughout the entire suspension travel range,
• maintaining the appropriate distance from brake system components and the bodywork.

Thanks to these features, the rim will perform well both in daily use and in more dynamic driving, where stability and predictability of the car's reactions are of key importance.

Condition, application, and benefits of choosing an aluminum rim

The rim comes from the secondary market, which allows for cost savings compared to new components while maintaining the original manufacturer's specifications. This solution is particularly beneficial when replacing a single damaged rim or when completing a wheel set with factory parameters.

Choosing an aluminum rear rim for the BMW F30/F31 brings a number of practical benefits:

• maintaining the factory handling characteristics of the vehicle,
• consistent look of the car thanks to the black rim finish,
• the ability to match tires with the appropriate profile and width to the rear axle.

This is a good solution for drivers who want to restore the original appearance and driving parameters of their BMW after damaging one of the rims or are planning an organized upgrade of their wheel set.
