Triple R Composites Ford Fiesta MK7.5 ST180/ST-Line Rear Diffuser
Give your Ford Fiesta MK7.5 a sharper, sportier rear end with this direct replacement rear diffuser. It fills the lower part of the rear bumper with a more aggressive, performance-inspired design.
A rear diffuser helps tidy up the airflow under the back of the car. This can reduce some of the messy air behind the bumper and gives your Fiesta a cleaner, more purposeful look similar to track cars.
- Direct replacement for the standard rear diffuser on Fiesta MK7.5 ST/ST-Line models (2013-2017)
- Sleek gloss black gel finish for a factory-style appearance
- Sporty styling that gives the rear bumper a lower and wider look
- Durable fibreglass construction with stainless steel fixing kit included
- Designed to work with ST180 rear spats when fitted together
Materials and finish
This diffuser is made from strong fibreglass, so it is light but rigid. It comes in a gloss black gel finish, as pictured, so it fits in well with most body colours and trims. The supplied stainless steel fixing kit helps resist rust and keeps the diffuser firmly in place.
Fitment and compatibility
Designed to fit Ford Fiesta MK7.5 ST/ST-Line models from 2013 to 2017 as a direct replacement for the original rear diffuser.
If you are fitting rear spats with this diffuser on your ST-Line, you will need the ST180 spats for correct alignment.
This product may require some trimming or sanding to achieve the best possible fit on your car.
This diffuser does not fit US spec Fiesta models.
