Vehicle Application and Placement

The presented window is designed for installation in the rear left side of the vehicle body, corresponding to the rear passenger area. This placement is crucial for both safety and driving comfort – correctly chosen glazing guarantees adequate visibility and structural integrity of the vehicle's side body.

Thanks to its precise fit for the BMW G20 series body, the window works seamlessly with factory seals, guides, and mounting elements, facilitating installation and minimizing the risk of leaks in the rear part of the vehicle.

Technical and Functional Characteristics

As an original BMW part, the rear left window has been manufactured according to the manufacturer's demanding standards for durability and safety. The glass used meets the standards for side windows in modern vehicles, ensuring:

• dimensional stability and proper fit to the body frame,
• adequate resistance to operational stresses,
• correct integration with factory door or side panel components.

Its position on the rear left side contributes to the torsional rigidity of the side body area and passenger comfort, especially on longer journeys.

Item Condition and Repair Application

The offered window comes from the segment of original used BMW parts, allowing for compliance with factory specifications at a more favorable repair cost compared to a new part. This solution is particularly useful for post-accident repairs, replacing damaged glazing after a stone impact, or during bodywork restoration.

Choosing an original used window reduces the risk of fitment issues common with cheaper aftermarket alternatives, while also maintaining the cohesive appearance of the BMW G20's side body line.

Using factory glazing in the rear left section of the BMW G20 body offers a range of practical benefits:

• preservation of the original geometry and aesthetics of the vehicle's side body,
• compatibility with factory mounting elements and seals,
• optical consistency with the vehicle's other windows,
• reduction of noise and leaks in the rear cabin area.

For body shops and repair services specializing in the BMW brand, this part represents a predictable, technically matched solution that simplifies repairs in accordance with factory guidelines.
