Triple R Composites Audi TTS/S-Line MK2 Facelift Rear Diffuser Fins
Give your 2011-2013 Audi TTS/S-Line MK2 Facelift or TT S-Line a sharper, more aggressive rear end with these Triple R Composites rear diffuser fins. They add a motorsport inspired look and help smooth airflow under the back of the car.
What these diffuser fins do
Rear diffuser fins guide the air as it leaves the underside of the car. This can reduce turbulence and help the car feel a little more stable at speed. You also get a much stronger visual impact at the rear, without changing the whole bumper.
- Sporty, track inspired look for the rear bumper
- Subtle aerodynamic benefit by tidying airflow under the car
- 3D printed Nylon12 construction – strong and light
- Supplied in black to match most factory rear trim
- Stainless steel fitting kit included for a clean, secure install
Construction and finish
Each fin is 3D printed in Nylon12, a tough plastic that is light and impact resistant. This method gives a precise shape and consistent finish. The parts are supplied in black, so they blend well with OEM rear valances and most diffuser sections.
Fitment and compatibility
Designed to fit Audi TTS/S-Line MK2 Facelift models from 2011-2013 and compatible TT S-Line models with the matching rear bumper style.
Please check your rear bumper matches the style shown on the product images before ordering.
