The black color refers to the finishing elements of the glass, allowing for an aesthetic integration with the factory door frames and body line. This solution helps maintain a cohesive, dynamic appearance of the car, which is particularly important for sporty versions like the M3.

Vehicle Placement and Installation Aspects

The window is intended for installation in the rear left door, which is important for both safety and user ergonomics. Correct placement on the vehicle ensures proper sealing, smooth operation of the window regulator, and correct interaction with the factory body components.

When installing, pay attention to:

• correct positioning of the glass in the channels,
