Purpose and fitment for BMW F20/F21

The presented housing is designed as a dedicated part for the left mirror in BMW F20 and F21 models. This ensures that the proper body lines, fitment with the mirror base, and compatibility with factory mirror glass and turn signals (if present in the vehicle's specific configuration) are maintained. Installation is performed in place of the original housing, which facilitates work for workshops and those involved in professional bodywork restoration.

Mineral Grey Metallic – B39 color

The Mineral Grey Metallic – B39 color is a popular, subtle shade of grey used in many BMW vehicles, which harmonizes well with both light and dark styling accents. Using paint in the same color code allows for reducing the need for additional painting or minimizing it, which shortens repair time and lowers costs. To maintain visual consistency of the bodywork, it is recommended to compare the shade with other body parts before installation.

Technical characteristics of the mirror housing

The housing belongs to the Exterior mirrors group, responsible for protecting the adjustment mechanism, mirror glass, and any additional elements such as turn signals or sensors. The design intended for installation on the left side of the vehicle ensures proper adhesion to the mirror base and stability during high-speed driving. The used nature of the part means it comes from disassembly, which is a beneficial solution for those looking for original components at a reasonable price, while maintaining factory geometry and material quality.

Use in repairs and upgrades

The mirror housing in Mineral Grey Metallic – B39 is suitable both for standard replacement of a damaged element after a collision and for visual refreshing of the vehicle. It can be used in:

• post-accident repairs of the left side of the body,
• visual restoration of the mirror after parking damage,
• restoring the original look of the car after previous non-factory modifications.

Thanks to the preservation of the factory shape and mounting points, the housing facilitates quick installation and correct positioning of the mirror relative to the body, which is important for both safety and aesthetics.
