Triple R Composites Toyota GR Yaris Rear Diffuser Fins
Give your Toyota GR Yaris a sharper, more purposeful rear end with this set of Triple R Composites rear diffuser fins. Designed to sit over the factory diffuser, they add extra depth and detail to the bumper for a clean, motorsport-inspired look.
Why choose this kit
- Set of 4 fins that mount over the original diffuser blades for a more aggressive style
- Extra aero blades between each pair of fins for a race-inspired rear profile and tidier airflow
- Media blasted black finish for a smooth, subtle, factory-style appearance
- Durable Nylon 12 construction – a tough, high quality plastic designed for exterior use
- Supplied with stainless steel hardware and double sided tape for a secure, neat fit
These fins follow the lines of the stock GR Yaris diffuser and sit proud of the bumper to give more definition. The added aero blades help guide air as it leaves the rear of the car, which can reduce turbulence and give a more focused, performance look. They are styled to complement both standard and modified cars without looking out of place.
The fins are manufactured from Nylon 12, a strong and slightly flexible plastic that copes well with daily road use. The media blasted surface gives a fine, matte texture, then is coloured black so it blends well with most diffuser and bumper finishes.
Fitment and compatibility
Designed specifically to fit Toyota GR Yaris models from 2020 onwards. They mount over the existing rear diffuser fins using the supplied stainless steel fitting kit, with double sided tape along the top edge to help hold them snug against the bumper.
Always test fit the parts before fully tightening any fixings or removing backing from the tape.
