Intended Use and Function on the BMW 3 G20 LCI Body

The presented roof trim set has been designed specifically for the BMW 3 Series G20 sedan, facelifted in 2023. The elements are mounted on the right and left sides of the roof, in the area of the factory roof rack and rail mounting points. They are responsible for:

• aesthetic finishing of the roof edges,
• covering the roof rack mounting points,
• maintaining the continuity of the body's styling line,
• providing a stable base for accessory load carrying systems. By maintaining the original geometry, the trims integrate well with the factory mounting points and do not require modifications to the roof structure.

Surface Finish and Alpinweiss 3 Color

The trims are prepared using prime-coated technology, enabling professional painting according to the requirements of body and paint shops. The base color used is Alpinweiss 3 – 300, characteristic of many BMW 3 Series G20 models. This surface preparation:

• facilitates achieving an even layer of topcoat paint,
• ensures better adhesion of subsequent layers,
• reduces the risk of shade differences compared to other body elements. To maintain visual consistency, it is recommended to paint the trims together with adjacent body parts or according to the vehicle manufacturer's procedure.

Installation in the Roof Rack and Rail Area

The set includes elements for both sides of the vehicle, allowing for simultaneous replacement of the entire pair and maintaining visual symmetry. Their placement on the vehicle on the right and left sides of the roof promotes precise fitting with:

• factory roof rack mounting points,
• door seals and side windows,
• other roof finishing trims. Proper fitting of these elements is important for both appearance and correct covering of the roof accessory mounting area.

Characteristics of a Used Product

The offered set comes from the group of original BMW parts in used condition. Such components are often chosen for collision repairs and for replacing damaged trims when maintaining the factory profile and body compatibility is a priority. A used finishing element allows for reduced repair costs while maintaining compatibility with the roof structure.

Practical Tips for Users

Before installation, it is advisable to verify body compatibility (G20 LCI sedan) and consult with a painter regarding the scope of work to properly select the coating preparation and painting technology. When equipping the car with additional roof load carrying systems, correctly installed roof trims are an essential element of preparation for further installations.
