Fiesta ST180/ST200 Rear Diffuser Extension

Give the rear end of your Fiesta ST a more aggressive, motorsport-inspired appearance with this Rear Diffuser Extension, finished in a sleek high-gloss black.

Designed specifically to fit the OEM Ford Fiesta ST180/ST200 rear diffuser, this extension adds additional styling and integrated aerodynamic fins without replacing the factory diffuser itself — creating a subtle but distinctive OEM+ finish.

⚠️ Important Compatibility Information

This is a diffuser extension, not a standalone rear diffuser.

It is designed to be installed directly onto the original factory-fitted Fiesta ST180/ST200 rear diffuser. The OEM diffuser is required for installation.

Premium OEM+ Styling

Finished in high-gloss black, the extension complements the factory rear diffuser while adding a more purposeful and aggressive appearance.

The integrated aerodynamic fins give the rear bumper a lower, sportier look while maintaining the overall styling of the Fiesta ST.

Easy Installation

The diffuser extension is supplied with the necessary fitting hardware and double-sided automotive tape, allowing for straightforward installation.

A 12mm x 2.5m roll of gloss black pinstriping is also included. This can be applied over the visible edge of the original diffuser to help create a cleaner, more seamless finish between the OEM diffuser and extension.
