The presented window is specifically designed as a part for the rear left section of the body, ensuring proper fitment with the door structure, factory seals, and guides. This allows for predictable installation without the need for modifications or edge adjustments.

Correct placement on the vehicle translates to proper cooperation with the window lifting mechanism, trim strips, and door frame, which is important for both sealing and interior acoustics.

Technical and Visual Characteristics

The side window features a black finish that harmonizes with factory BMW body elements such as pillars, seals, and decorative trim. This coloring helps maintain a cohesive look of the car's side profile after replacing the part.

The AS3 designation indicates an advanced glass construction, adapted to safety and user comfort requirements. The use of the appropriate type of glass is important for passenger protection, as well as for the proper functioning of coatings and layers responsible for light filtration.
