Purpose and function of the component

The presented sill strip has been designed as a factory element for the side body area of the BMW 1 Series E87N generation after the facelift (LCI). Mounted on the left side, it is responsible for:

• protecting the sill from dirt and minor mechanical damage,
• completing the side line of the body in accordance with the factory design,
• maintaining the correct visual geometry of the lower part of the bodywork.

Thanks to the preservation of the original geometry and mounting points, the strip allows for precise fitting to the body without the need for modifications.

Color and paint matching

The component is finished in Black Sapphire Metallic - 475, characteristic of many BMW configurations. The metallic paint ensures consistency with the factory body finish, which in many cases allows for reducing or completely omitting additional paint work. This is particularly beneficial for:

• replacing a single strip after local damage,
• accident repairs where the rest of the body remains in the original paint,
• renovations where maintaining the factory look is a priority.

Installation characteristics

The sill strip is intended for installation on the left side of the vehicle, in accordance with the factory body layout of the BMW E87N LCI. The original design ensures:

• compatibility with factory mounting points in the sill,
• stable seating without play or stress,
• proper adhesion to the body surface.

As a result, the component works well both for repairs performed in professional body and paint shops, as well as in independent workshops that prioritize OEM parts.

Condition and practical application

The strip comes from disassembly and is offered as a used part, which allows for optimizing repair costs while maintaining the manufacturer's original specifications. This type of component is particularly useful when:

• the side sill area has been damaged as a result of a scrape or minor collision,
• it is necessary to replace the element due to corrosion or previous body repairs,
• you want to maintain the factory look without using aftermarket parts with different geometry.

Choosing an original sill strip makes it easier to maintain the visual and technical consistency of the entire side of the body.
