Purpose and fitment

The window has been designed specifically for the BMW Z4 E86 model as a component mounted in the rear left area of the body. The appropriate edge profiling and factory AS2 glass characteristics allow for maintaining the consistent side line of the car, proper adhesion to seals, and compatibility with original mounts.

Thanks to maintaining the specific geometry of the Z4 E86 body, the installation process is predictable for an experienced body and glass repair shop, without the need for modifying the bodywork or adjacent components.

Technical characteristics of the side window

The glass marked with the AS2 class meets the requirements for light transmission and mechanical resistance provided for side windows. The construction ensures:

• dimensional stability necessary for proper seating in the body frame,
• appropriate rigidity, reducing vibrations and noise while driving,
• compliance with the factory safety standard used in BMW.

As a component from the Car windows group, the side window works with seals, trim strips, and guide mechanisms, creating a tight and functional side glazing system.

Condition, origin, and benefits of choosing a used part

The offered window is a used component, sourced from the dismantling of a BMW vehicle. This type of component allows for maintaining the manufacturer's original specification while reducing repair costs compared to a new part. In practice, this means a beneficial combination of factory fitment and an attractive purchase price.

For many BMW Z4 E86 users, choosing a window from the secondary market is a rational solution for post-accident repairs, bodywork corrections, or replacing damaged glazing after a collision or act of vandalism.

Application in BMW Z4 E86 repairs and restorations

BMW Z4 E86 Rear Side Window Glass Glazing Left N/S will work well both for standard replacement of damaged glass and for more extensive bodywork in the rear part of the body. It is particularly useful in situations where:

• the window has cracked or shattered as a result of an impact,
• replacement of the component is necessary after repairing the side body panel,
• the completeness of the glazing is being restored in a car after partial dismantling.

A properly selected side window helps maintain the correct structural rigidity of the body in the rear cabin area and preserve the aesthetics of the side line characteristic of the BMW Z4 E86.
