Purpose and fitment for BMW E90 LCI

The presented side skirt has been designed specifically for the facelift (LCI) version of the E90, which means it features a construction compatible with factory mounting points and body lines. Its placement on the left side of the vehicle allows for the precise replacement of a damaged part without the need for modifications or fitting aftermarket alternatives.

Thanks to the use of original geometry, the side skirt works with factory covers, seals, and mounts, maintaining the proper rigidity of the sill area and the correct alignment of the side body line characteristic of the M Sport version.

Black Sapphire Metallic – 475 finish

The Black Sapphire Metallic – 475 color is a popular dark metallic paint from BMW, often found in configurations with the M package. Using the same shade on the side skirt allows for visual consistency across the entire side of the vehicle, reducing the need for extensive painting of adjacent elements.

The metallic finish harmonizes well with the dynamic styling of the M Sport package, highlighting the contours and the sill line in both daylight and artificial light. This solution is particularly beneficial for accident repairs or partial body restoration, where faithfully recreating the factory appearance is a priority.

Characteristics of the used component

The side skirt comes from dismantling, meaning it is a used part that retains the manufacturer's original specifications. Such components are often chosen for repairs where the priority is combining factory fitment with control over service costs.

A used body component allows for the preservation of the proper geometry of the sill area while reducing waiting times for the availability of new parts. In practice, this translates into more efficient body and paint repairs in workshops specializing in the BMW brand.

Use in M Sport repairs and upgrades

The left side skirt in Black Sapphire Metallic is particularly useful for:

• repairs following side collisions in the sill area,
• restoring the complete look of the M Sport version after mechanical or corrosion damage,
• upgrading a standard E90 LCI model to the M package specification while maintaining the original character of the body.

Due to its factory origin, the element fits well into the side line of the car, which makes it easier to achieve even gaps and proper alignment with the doors and other body panels.

Support in part selection and repair time

When choosing used body components, correct fitment for the specific model version and a conscious approach to repair planning are key. It is worth noting how the availability of components from dismantling affects workshop workflow organization and reduces vehicle downtime.
