Purpose and Fitment for BMW E90 / E90N LCI

This side window is dedicated to the rear left side of the body, meaning the driver's side rear door.

Using a window that is compliant with the design of the facelifted BMW E90 helps maintain the visual consistency of the bodywork and the correct geometry for sealing.

The glass construction is prepared for use in rear doors, where noise reduction, appropriate light transmission, and resistance to stress from frequent opening and closing are important.

• proper sealing of the space between the door and the body,
• maintaining the original character of the glazing in the BMW 3 Series E90.

Benefits of Using an Original BMW Side Window

Choosing an original side window for the BMW E90 offers a range of practical advantages. The part is designed for the specific geometry of the door, which translates to precise fitting with the frame and seals. This reduces the risk of leaks, rattles, or excessive vibrations during driving. The appropriate thickness and structure of the glass also contribute to acoustic comfort inside the cabin, which is particularly noticeable at highway speeds.

The left rear side window is also an important passive safety element – correctly selected glass works with the door structure, ensuring predictable behavior in the event of a collision. Using a component that aligns with the manufacturer's original specifications helps maintain the vehicle's structural integrity.
