Purpose and fitment

The presented spoiler is a factory component designed for the third-generation Ford Focus in the ST-Line trim, mounted on the tailgate. Thanks to a design consistent with the manufacturer's specifications, it ensures proper fitment to the body contours and stable seating on the edge of the tailgate. Its original Ford origin guarantees the preservation of factory geometry, which translates into proper adhesion to the bodywork, the absence of unnatural gaps, and predictable behavior of the component at higher speeds.

Visual characteristics and Stealth - B9 color

The Stealth - B9 color is a dedicated shade used by the manufacturer, allowing for consistent matching to the body paint in this color reference. As a result, the spoiler integrates harmoniously with the car's lines without the need for additional painting, while maintaining compliance with the factory palette. The dynamic profile of the wing emphasizes the sporty character of the ST-Line version, visually lowering the rear of the car and giving it a more aggressive, yet still elegant silhouette. This solution is particularly valued by users who want to maintain an original, consistent design rather than using random aftermarket replacements.

Aerodynamic and functional features

The tailgate spoiler serves not only a stylistic function but also a practical one. The properly shaped edge of the wing helps to organize airflow at the rear of the body, which promotes stability at higher speeds and reduces turbulence in the tailgate area. In daily use, this improves the perceived stability of the car on the road, while at the same time maintaining full functionality of the tailgate – the spoiler does not restrict its opening or access to the cargo space.

Condition, installation, and service application

The item comes from disassembly and is offered as a used OEM spoiler, which allows for an economical repair or restoration of the car's factory appearance after a collision or tailgate damage. It is a good solution for both body shops and individual users looking for an original component for their Focus. Installation takes place in the factory location, using the mounting points provided by the manufacturer. With proper preparation of the tailgate, it is possible to achieve an effect similar to factory installation, without the need for interference with the body structure.

Benefits of using an original spoiler

Using an original ST-Line wing allows you to:

• restore the factory look of the rear bodywork after accident repairs,
• maintain stylistic consistency with other elements of the ST-Line package,
• maintain compliance with the factory color scheme thanks to the Stealth - B9 paint,
• avoid fitment issues typical of low-quality aftermarket replacements.
