Purpose and fitment

The side skirt has been designed specifically for the M Sport version of the BMW 3 Series E90 generation after the facelift (LCI) and is mounted on the left side of the vehicle. Thanks to the factory mounting geometry, it maintains proper alignment with the body, which facilitates installation and reduces the risk of stress on the bodywork.

The original design ensures compatibility with factory mounting points, allowing for the replacement of a damaged component without the need for bodywork modifications or fitting aftermarket replacements.

Finish and color

The side skirt is finished in Black Sapphire Metallic paint with code 475, characteristic of many BMW sports configurations. The metallic coating adds depth to the body and emphasizes the side line of the car, blending well with both dark and lighter body colors.

The factory surface finish makes it easier to match the component to other body panels in the same color, which is important for accident repairs and restoring the vehicle's original appearance.

Technical characteristics of the component

The M Sport side skirt serves a protective and aesthetic function in the lower part of the vehicle's side. The design intended for installation on the left side ensures proper guidance of the sill line and protection of this area against dirt and minor mechanical damage.

The component has a specific weight, which is important when selecting parts in accordance with BMW factory specifications – maintaining a similar mass helps keep the proper load distribution and does not negatively affect the vehicle's handling characteristics.

Condition and use in repairs

The offered side skirt is a used original component, which in practice means it retains its factory geometry and compatibility with the body line of the BMW 3 Series E90 LCI. This solution is often chosen for accident repairs when the priority is fitment and compatibility with the factory M Sport package.

Using an original, used side skirt allows for cost reduction compared to new parts, while maintaining the proper appearance and protective function in the sill area.
