• reducing air noise and sound entering the cabin,

This ensures that the exterior mirror operates stably, and the driver maintains a clear view in the mirror even at higher speeds.

This precise fit allows for installation without modifications, maintaining factory alignment and proper adhesion to the upholstery and mirror housing.

Characteristics of the Used Component

The offered mirror foam triangle is a used part, sourced from disassembly. This solution allows for maintaining the original vehicle specification while optimizing repair costs. A used component from the Mercedes range retains its proper geometry and structure, which is crucial for correct mirror seating and maintaining a seal in the front right part of the door.

For many users, choosing an original, used component is advantageous as it ensures material and structural compatibility with other door assembly elements.

Benefits of Using an Original Mirror Foam Triangle

Using this component in your Mercedes C W204 offers a range of practical benefits:

• Stable Mirror Mounting – proper support and stiffening in the mounting area.
• Improved Interior Acoustics – the foam reduces the penetration of external noise.
• Factory Fit – matches the shape of the door and pillar without requiring modifications.
• Consistent interior and exterior appearance on the passenger side of the door.

This is particularly important for collision repairs or mirror replacements when you want to preserve the original character of the car and ensure the proper functioning of the exterior mirror.
