Triple R Composites Audi RS4 B9.5 Avant Side Skirt Splitters
Give your Audi RS4 B9.5 Avant a sharper, more purposeful look with these Triple R Composites side skirt splitters. They run along the lower edge of the factory side skirts to make the car look lower and wider, without major changes to the bodywork.
The splitters help smooth the side profile of the car. This can reduce some of the messy air that moves around the sides at speed, while giving your RS4 a more aggressive road presence.
Why choose this kit
- Designed to fit Audi RS4 B9.5 Avant models from 2019-2025
- Gloss black gel coat finish for a clean, factory-style appearance
- Manufactured from strong GRP (glass reinforced plastic) for long term durability
- More robust than typical ABS plastic alternatives
- Supplied with a stainless steel fitting kit for a secure install
- Simple bolt-on upgrade that works with the original side skirts
Material and finish
Each splitter pair is made from GRP, which is glass fibres set into a hard resin. This material is tough, resists cracking better than many basic plastics, and has been widely used in motorsport and aftermarket body parts for years.
The gloss black gel coat is applied in the mould, so the finish is smooth and consistent straight out of the box. On many cars this can be fitted without the need for painting, matching other gloss black trim on the RS4.
Fitment and compatibility
This kit fits Audi RS4 B9.5 Avant models from 2019-2025 that retain the original side skirts.
Check your car is the B9.5 facelift RS4 Avant model before ordering.
Use the vehicle lookup on our site or check the Vehicle Fitment tab for full details before ordering.
The splitters mount to the underside of the side skirts using the supplied stainless steel hardware. Basic hand tools are usually enough. Professional fitting is recommended if you are not confident working on exterior trim.
