- Clips into the original bumper mounting points
- Uses two of the original fixings for secure fitment
- Gloss black finish for a clean, factory plus appearance
- Durable fibreglass construction for strength and low weight
Style and performance
This rear diffuser is designed to sit under the rear bumper and break up the flat area at the back of the car. By guiding the air more smoothly away from the underside, it can help reduce drag at higher speeds. The deep fins give a track car look without being over the top, so it suits daily driven cars as well as show builds.
Construction and finish
The diffuser is manufactured from fibreglass, a strong but lightweight material made from glass fibres and resin. It is supplied in a glossy black gel coat, so it can be fitted and used straight away.
For the best possible finish and colour match to your car, we recommend having this product professionally sprayed before final fitting.
Fitment and compatibility
This Triple R Composites rear diffuser is designed to fit Ford Fiesta MK6 ST150 models from 2004 to 2007. It is a direct replacement for the original rear diffuser, clips into place, and reuses two of the factory fixings.
Please test fit the diffuser on the car before painting or making any permanent changes.
