Characteristics of the M Double Spoke 436 rim design

The presented rim belongs to the BMW Wheels category with a sporty profile, featuring an elaborate double-spoke layout. This rim geometry promotes stability at higher speeds and improves the rigidity of the entire structure. The material used is aluminum, which helps reduce unsprung mass compared to classic steel wheels and positively influences suspension response and ride comfort.

The grey finish of the rim is visually neutral while effectively highlighting the shape of the spokes and emphasizing the body lines. The rim has been designed to work with BMW F-series chassis systems, ensuring proper mounting parameters and maintaining the correct suspension geometry.

Mounting parameters and compatibility

The rim features a dedicated bolt pattern and center bore diameter matched to BMW hubs, which facilitates installation and ensures proper seating on the hub. The number of holes has been selected in accordance with the standard used in F20, F21, F22, and F23 models, allowing the rim to work with factory mounting bolts.

The ET offset and rim width have been selected to maintain the correct wheel line relative to the body and suspension components. The properly selected ET parameter helps avoid interference with brake calipers and suspension elements while allowing for a visually consistent wheel track. The rim diameter allows for the use of tires with a profile typical for high-performance versions, which promotes handling precision.

Purpose, application, and condition

The rim was developed for BMW F-series cars with hatchback and coupe/convertible bodies, where both appearance and stable handling are important. The aluminum construction performs well in daily use while allowing the driver to utilize the potential of these models' suspension and steering systems. The product comes from the Wheels category, meaning it is intended as a component of the running gear, not as a decorative accessory.

The offered item is in Used condition, making it an attractive solution for those looking for an original BMW rim at a reasonable price, while maintaining factory geometry and mounting parameters. This is a good solution both for replacing a damaged rim and for completing a set of summer or winter wheels.
