Triple R Composites Audi RS5 B9 Rear Diffuser Extensions
Give your Audi RS5 B9 a sharper, more purposeful rear end with these Triple R Composites rear diffuser extensions.
Designed to sit at each side of the rear diffuser, they add extra width and a lower, more aggressive look. The car appears closer to the ground and more planted without needing to change the whole bumper.
- Subtle track-inspired styling for the rear of your RS5
- Helps give the diffuser a wider, more aggressive stance
- Factory-style black finish that works with most colour schemes
- Strong, lightweight Nylon 12 construction for long-term use
- Supplied as a pair for both sides of the rear diffuser
Material and finish
These extensions are made from Nylon 12, a tough, lightweight plastic that resists impacts and cracking. The surface is media blasted, which gives a fine, even texture, then coloured black for an OEM-style finish.
If you prefer a body colour look, a good body shop can prep and paint them to match your RS5.
Installation guidance
We recommend bonding the extensions to the diffuser using a quality polyurethane adhesive, such as Tiger Seal, for a secure fit.
Professional installation is recommended to ensure safe bonding and correct alignment.
Fitment and compatibility
Designed for Audi RS5 B9 Sportback and coupe models from 2017 to 2019.
Please check your car is the RS5 B9 Sportback and that the rear diffuser matches the standard RS5 B9 Sportback design before fitting.
Use the vehicle lookup on our site or check the Vehicle Fitment tab for full details before ordering.

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
