Design characteristics and BMW fitment

The wheel has been specifically designed for BMW F20, F21, F22, and F23 models, ensuring proper wheel arch clearance and predictable suspension behavior. The rim profile and carefully selected offset promote stability at higher speeds and during dynamic maneuvers. As a result, the driver receives factory-spec fitment for the chassis without the need for spacers or modifications.

Material, color, and finish

The wheel is made of a lightweight aluminum alloy, which helps reduce unsprung mass compared to classic steel solutions. A lighter rim promotes faster suspension response, improves ride comfort, and enhances handling precision. The Ferric Grey color gives the wheel a subtle yet clearly sporty look that complements both light and dark body paints. The aluminum construction also facilitates any potential surface refurbishment processes.

Geometric parameters and driving performance

The wheel diameter is matched to popular tire sizes used in compact BMW models, making it easy to configure a wheel-tire set for daily use or a more sporty driving style. The rim width allows for the installation of tires with various profiles, providing proper tread support and lateral stability in corners. The applied offset (ET) has been developed to maintain correct suspension geometry, minimizing the risk of rubbing against the wheel arch when using properly selected tires.

Wheel mounting and chassis compatibility

The wheel uses the standard BMW bolt pattern and center bore, ensuring seamless compatibility with hubs and factory wheel bolts. The number of mounting holes guarantees proper load transfer during braking and acceleration, as well as even distribution of forces across the entire hub circumference. This solution maintains the stability of the connection between the wheel and suspension, which is crucial for both daily city driving and higher highway speeds.

Practical application and benefits of choosing a used wheel

As an item in the Wheels category, this model works perfectly both as a replacement for a damaged rim and when upgrading to a more visually sporty set. A used BMW alloy wheel allows for cost savings compared to a new component while maintaining the manufacturer's original specifications. This is a great solution for drivers who want to maintain the car's stylistic consistency using the factory M Styling 436 design while optimizing their budget for maintenance or upgrades.
