Purpose and body fitment

The presented mirror belongs to the Wing Mirrors category and has been designed specifically for the Seat Leon Mk3 5F model. It is mounted on the front left side, which guarantees the correct field of view for the driver and compliance with the factory body geometry. The design, based on the vehicle manufacturer's solutions, allows for maintaining proper mounting rigidity and stability when driving at higher speeds.

Color and finish Mythical Black Metallic – Y9T

The Mythical Black Metallic – Y9T paint is a dark, metallic shade that blends well with both light and dark body colors. Thanks to the metallic structure, the surface of the mirror harmonizes with the factory paint, reducing the need for additional painting when replacing the component with one in the same color code. This is a practical solution for users who want to quickly restore the consistent appearance of the side of the body.

Performance characteristics and installation

The mirror has been prepared as a replacement part, enabling direct installation in place of the original component on the left front mount. The design intended for this Seat model ensures:

• proper fit to the shape of the door and pillar,
• stable seating in factory mounting points,
• maintenance of the correct viewing angle after proper adjustment.

Such a solution facilitates the work of body and paint shops as well as services dealing with the replacement of body components after collisions or operational damage.

Brand and origin of the component

The mirror comes from the Seat brand, which means compliance with factory design standards for the Leon Mk3 5F model. Using an original component allows for maintaining the stylistic consistency of the vehicle and also reduces the risk of problems with fitting the housing to the line of the doors and side windows. The product is offered as a used part, which is a cost-effective solution while maintaining compliance with the vehicle's design.
