Audi RS4 Avant (B9) exterior styling & carbon fibre parts

R44 Performance stocks 20 exterior styling parts for the 2017–2024 Audi RS4 Avant (B9). Parts include front splitters & lips, number plate holders, rear side splitters and side skirts, from brands including Maxton Design, R44 Merch, Bimecc, twistNfix, MHC.

Exterior parts range from subtle OEM-style upgrades to full carbon fibre aero. Where a part comes in more than one finish, pre-preg and dry carbon give the most consistent weave and the lowest weight, while gloss black and paint-matched parts suit a factory look. Many splitters, side skirts and diffusers are designed as matching sets, so you can build a consistent look over time.

Every part on this page is listed for the RS4 (B9), but bumpers and rear ends can differ between body styles, trim levels (such as M Sport or S line) and facelift versions – check the fitment notes on each product. Need help planning a look? Chat to our team, or book fitting at R44 HQ in Wembley, London.

RS4 (B9) Exterior Styling FAQs

Will these parts fit my RS4 (B9)?

Every part on this page is listed for the Audi RS4 Avant (B9). Some parts only fit certain body styles, model years, or pre- or post-facelift (LCI) cars, so check the fitment notes on each product page. If you're unsure, send us your registration or VIN and our team will confirm fitment before you order.

What exterior styling parts are available for the RS4 (B9)?

R44 Performance lists 20 exterior styling parts for the Audi RS4 Avant (B9), including front splitters & lips, number plate holders, rear side splitters and side skirts. Brands include Maxton Design, R44 Merch, Bimecc, twistNfix, MHC, and every part is listed for the RS4 (B9) – check each product page for body style and model-year fitment.

What's the difference between pre-preg, dry and wet carbon fibre?

Pre-preg carbon uses carbon sheets already impregnated with resin, cured under heat and pressure for a consistent, strong finish – usually with a gloss lacquer. Dry carbon normally means pre-preg cured in an autoclave with less resin, so it's lighter and stiffer and often has a matte or satin finish. Wet-laid carbon is resin applied by hand – cheaper, but heavier and less consistent.

Will a front splitter or diffuser reduce ground clearance on my RS4 (B9)?

Front lips and splitters sit lower than the standard bumper, so take more care on steep ramps, kerbs and speed bumps – especially if your RS4 (B9) is also lowered. Any clearance notes from the manufacturer are listed on the product page.

Can R44 Performance fit exterior styling parts to my RS4 (B9)?

Yes. Our technicians fit exterior styling parts at R44 HQ in Wembley, London – contact our team for a quote and availability. We also deliver across the UK and worldwide if you'd rather use your own fitter.
