Purpose and fitment

The presented sill trim is designed as a component mounted on the left side of the vehicle, in the lower part of the body. The AERO profile ensures proper adhesion to the sill, which reduces the risk of dirt accumulation and improves paint protection in the sensitive area of the cabin entrance. As a part from the Sill trims group, it is designed to work with factory mounting points, which facilitates installation and maintenance.

Finish and color

The trim is finished in Astro Black Metallic - A25, characteristic of original MINI components. The metallic paint coating ensures consistency with the factory body paint, while also effectively masking minor operational dirt. A properly selected shade allows for maintaining a uniform appearance of the side of the car after replacing a damaged element.

Performance characteristics

As a body component from the AERO package, the sill trim influences the airflow along the side of the car and visually lowers the silhouette. In practice, this means a more dynamic look for the vehicle and better protection of the lower door edge against stone chips and dirt. The used OEM construction ensures proper fitment with adjacent panels, which minimizes the need for additional adjustments during installation.

Condition and service application

The item is offered as a used part, which is a cost-effective solution for post-accident repairs, spot body corrections, or restoring the car to its original visual specification. Choosing an original sill trim allows for maintaining the factory geometry of the side line and compatibility with existing mounts and covers.

Selection and additional resources

In case of doubts regarding the compatibility of the element with a specific equipment version or vehicle year, it is worth using the OEM number and interchangeable numbers visible in the technical specification. When selecting parts, the vehicle's VIN number can also be helpful, as it allows for precise matching of the component to the factory configuration.
