Purpose and fitment

The presented window glass has been designed specifically for BMW E46 series models as a side component for the front right door. Its placement in the front, right zone guarantees proper geometry, fitment to the door frame, and compatibility with factory seals and guides.

The green tint of the glass is characteristic of many factory BMW configurations, which allows for maintaining a uniform appearance of the vehicle's entire glazing without color differences between the windows.

Technical characteristics of AS2 glass

The side window is made of glass marked with the AS2 class, which in practice means appropriately selected light transmission and safety parameters required for side windows in passenger cars. The glass construction is optimized for:

• proper visibility in various lighting conditions,
• cooperation with the window lifting and lowering mechanism,
• stable seating in the door frame.

Thanks to this, the component works well with the factory window mechanism, reducing the risk of jamming or excessive stress in the guides.

Condition and service application

The window is a used component, which in practice means it comes from disassembly and can be an attractive solution for post-accident repairs, replacing damaged glass, or restoring the car to a condition close to factory specifications. Using an original component from the same BMW E46 model group promotes maintaining proper body geometry and correct operation of door mechanisms.

Such a solution is particularly beneficial in the case of body and paint repairs, where both dimensional fitment and visual consistency with the vehicle's other windows are important.

Benefits of using an original side window

Using a factory side window in a BMW E46 allows for maintaining the stylistic consistency of the body and preserving the performance parameters intended by the manufacturer. The main advantages include:

• precise fitment to the door frame and seals,
• compatibility with the factory window lifting mechanism,
• maintaining a uniform green tint across the vehicle's entire glazing,
• the possibility of an economical repair in case of damage to the front right window.

Thanks to this, the component fits well into professional body repairs, especially where compliance with the original BMW specification is a priority.
