Purpose and fitment for BMW G20

The presented glass is dedicated to the rear right side of the BMW G20 series body, which means its shape, bending radii, and mounting method comply with the manufacturer's factory requirements. Proper fitment to the door frame minimizes the risk of leaks, unwanted stress, and issues with the window regulator mechanism.

The original construction ensures:

• proper adhesion to seals and trim strips,
• stable seating in guides and mounts,
• preservation of the factory side profile line of the BMW body.

Technical characteristics and color

The glass belongs to the group of glazing marked as AS3, which in practice means special tinting and light transmission parameters, adapted for use in the rear zone of the vehicle. The applied black finish allows for an aesthetic combination with factory strips, frames, and pillars, creating a visually cohesive side profile of the car.

Thanks to the appropriately selected color and edge structure, the glass works well with other body elements, reducing light reflections and improving optical comfort for rear-seat passengers.

Function in the body structure

The side rear window in the BMW G20 serves not only as a glazed element but is also part of the side body structure. A properly selected and installed component helps maintain:

• rigidity of the door area and rear pillar,
• correct operation of seals in terms of acoustic insulation,
• protection against weather conditions in the rear part of the cabin.

Choosing an original BMW glass reduces the risk of fitment issues that may occur with aftermarket parts having less precise dimensional tolerances.

Condition of the element and benefits of choosing a used part

The offered glass is a used component, which means it comes from vehicle dismantling but retains the manufacturer's factory specifications. For the user, this means the possibility of obtaining original glass with the correct geometry and parameters at a lower cost than a new element. This type of solution is particularly beneficial for post-accident repairs or replacing individual windows within the side body area.

Before installation, it is recommended to perform a standard inspection of the edges, working surface, and mounting points to ensure proper cooperation with the lifting mechanism and door seal.

OEM compatibility and safety

As an OEM element, the glass was designed to meet the safety and comfort requirements applicable to the BMW G20. The appropriate glass thickness, type of lamination, and tinting parameters are adapted for operation in the rear zone of the vehicle, supporting passenger protection and improving driving conditions on sunny days.
