Purpose and fitment

The presented window is a component dedicated to the rear body section on the left side in BMW 5 Series G30 generation and M5 F90 models. Its placement in the rear seat area affects passenger comfort, proper interior lighting, and the maintenance of factory glazing geometry.

Thanks to the factory profile and the correct bending radius, the glass works with original seals, guides, and the door frame, which facilitates installation and helps maintain the tightness of the body system.

Technical characteristics of the glass

The AS2 type marking indicates tempered glass with appropriately selected light transmittance, compliant with the requirements for rear side windows. This type of glass provides:

• an appropriate level of transparency for rear seat passengers,
• increased resistance to mechanical damage compared to standard glass,
• a controlled breakage pattern, reducing the risk of serious injury.

As an original BMW component, the glass maintains the correct thickness, shape, and inclination angle, which is important for both aerodynamics and interior acoustics. Correctly selected glazing helps reduce wind noise and vibrations when driving at higher speeds.

Benefits of using an original side window

Choosing an original rear left side window for the BMW F90 G30 allows you to maintain the visual and technical consistency of the entire window set. Key advantages include:

• Factory fitment – no modifications required, proper alignment with the door frame and seals.
• Stable optical parameters – no image distortion, which affects passenger comfort.
• Compatibility with factory body components – maintaining the original side line and the stylistic character of the BMW.

This solution is particularly recommended for accident repairs, replacing damaged glass, or restoring the car to its factory specification.

Condition of the item and practical application

The glass comes from the secondary market, making it a cost-effective alternative to a new component while maintaining its original origin. This type of component will work well in both professional body and paint shops and workshops specializing in the restoration of premium cars.

Before installation, it is recommended to perform a standard inspection of the edges, working surface, and fitment to the door frame to ensure proper sealing and the absence of stress in the glass structure.
