Intended Use and Function of the Part

The M-Package side skirt trim is responsible for the aesthetic finishing of the lower part of the vehicle's side and for protecting the sill area from mechanical damage and dirt. Mounted on the left side, it works with other M package elements to create a cohesive, dynamic look characteristic of the sporty versions of the BMW E87.

The part is designed as a factory component, meaning it maintains the correct geometry, mounting points, and compatibility with original sill clips and covers for this model.

Color and Visual Matching

The finish in Montegoblau Metallic - A51 ensures compatibility with the factory BMW paint palette. This allows the trim to blend harmoniously with the body line, without the need for additional color matching during installation, provided the vehicle has the same paint code.

The metallic paint structure emphasizes the sporty character of the M-Package, and accurate shade reproduction facilitates maintaining a uniform appearance of the entire body after replacing the part.

Technical Characteristics and Installation

As a part from the Side Skirts category, the trim is prepared for installation at the factory mounting points in the BMW E87. The design anticipates cooperation with original clips and covers, which simplifies servicing and reduces the need for additional bodywork modifications.

Its placement on the left side of the vehicle allows for precise fitting to the sill contour and door line, which translates to proper alignment with other body elements. The used nature of the part means maintaining the original installation specifications while offering an attractive cost-to-quality ratio.

Practical Application and Benefits

The use of this side skirt trim is particularly beneficial in cases of:

• post-accident repairs in the left sill area of the body,
• restoring the complete M-Package look on the BMW E87,
• local bodywork renovations when the existing part is damaged or corroded,
• maintaining color consistency when replacing individual side components.

By preserving the factory geometry, the trim allows for the restoration of the vehicle's correct side profile and ensures proper drainage of dirt and water in the sill area.
