SPECIFICATIONS

Inspired by Rieger’s signature German design language, our Carbon Fiber Rieger Style Rear Diffuser brings a sharper, more aggressive look to the rear of your B8.5 Audi A5 or S5. Designed specifically for quad-tip exhaust setups, this piece mimics the iconic Rieger styling known for clean aerodynamic lines, pronounced fins, and a purposeful fit that enhances the car’s rear stance without being overdone.

Crafted from high-quality dry carbon fiber, this diffuser is a full replacement part—not a cheap overlay. It offers a flawless weave, crisp detailing, and significantly reduced weight compared to the factory plastic unit. The aggressive fins and wide quad-tip openings transform the rear end with a distinct Euro-performance feel while maintaining clean OEM-style integration. A perfect upgrade for those who appreciate both style and substance.

Key Features:

- OEM Quality

- Molded Directly from the Genuine Version for Precise Fitment

- Made with Genuine Japanese TORAYCA™ Carbon Fiber

- Gloss 3*3 Twill Carbon Weave

- Made to Order (2-3 Weeks Production Depending on Size)

FAQs for the Audi Carbon Fiber Rieger Style Rear Diffuser for B8.5 A5 & S5

Does This Fit My Car?

To check if a part fits your vehicle, please utilise the 'Fitment' section on our product description. If your vehicle is listed, the part will fit your car. If you're unsure, our fitment bar is also available to help you find compatible products for your specific make and model.

If this product is promised to fit your car, and does not, we have a 100% full money-back refund policy.

What is Japanese TORAYCA™ Carbon Fiber?

TORAYCA™ is a carbon fiber material made by Toray Industries in Japan, its the same company that supplies carbon to brands like Lamborghini, McLaren, Aston Martin, and even Ferrari. It’s the real deal used in supercars, race cars, and aerospace builds where strength, weight, and heat resistance actually matter.

We use genuine Japanese TORAYCA™ Carbon Fiber in all our wet and dry carbon parts. Why? Because it’s lighter, stronger, and more reliable than the cheap composite blends flooding the market from Aliexpress. TORAYCA™ holds up under pressure, keeps its shape over time, and doesn’t fade or fray like lower-grade alternatives.

This is the carbon you use when performance isn’t optional. If you're building a car that turns heads and doesn’t cut corners, TORAYCA™ is the standard.

And it’s the only carbon we trust.

Are There Any Discounts Or Promotions?

Euro Empire Auto regularly offers discounts and promotions. Stay updated by subscribing to our email or SMS notifications. You can also check our social media platforms or contact our customer service via Live Chat for the latest deals.

Do You Have Financing Options like Afterpay?

We offer payment plans through partnerships with Afterpay. Paying in 4 equal instalments. Please note that application approvals are handled by our partners and we do not receive any sensitive financial information.

Do You Include Instruction Manuals?

Instruction manuals are included with select products. We strongly recommend professional installation to ensure optimal performance and safety. Euro Empire Auto is not liable for damages incurred during self-installation.

What Is The Difference Between Wet And Dry Carbon Fiber?

Dry carbon fiber is the premier choice, being 70% lighter than wet carbon and constructed entirely from carbon material, providing a distinct, symmetrical weave. Wet carbon fiber, while slightly heavier, is also high quality and involves applying carbon material onto a mold. Both options offer excellent performance and aesthetic appeal.

How Do I Contact Customer Support?

I recently upgraded my luxury car with a few performance and styling parts from Euro Empire Auto, and I couldn’t be happier with the results! Their parts are top-quality and have really enhanced the way my car looks and feels on the road. From intake upgrades to sleek body components, everything arrived exactly as described and clearly chosen with care you can tell they only stock trusted, premium brands. The team was super helpful in answering my questions and making sure I picked the right parts for my car. If you’re thinking about upgrading your vehicle, whether for performance or just to give it a more aggressive look, I highly recommend checking out their site.

Had been hunting for a clean carbon fiber spoiler for my BMW and came across Euro Empire Auto. Glad I did! The part arrived quicker than expected, fit perfectly, and gave the car that subtle aggressive touch I was going for. Really liked that they sent install tips too. Great experience overall, definitely coming back for more upgrades.

Sam reached out at the start of 2025 and was looking to be part of my show build on my A45 over in the UK! We agreed a sponsorship and a deal of how we can grow his business in the UK! Sam was amazing, I had weekly updates of the Carbon Bonnet he was custom making me! I then found out when the bonnet came the Vents could be exposed or unexposed! This is huge considering the weather in the UK and nothing I have seen be done before either! Simple 12 screws is the difference! The bonnet came on time and very well prepped! In a huge crate with all the safety options! I have now had it ppfd and fitted to the car! Now time to get some content and get it promoted all over Socials! I would highly highly recommend EEA, The best quality of carbon I have seen!

I've known the guys at EUROEMPIREAUTO for a couple of years now and they are by far above and beyond when it comes to quality parts and top of the line service. They made it so easy to answer all my questions and guide me to what I wanted done. For me, customer service and communication is the key to a good business relationship and they do an excellent job at it. A bonus is that they're located in Australia for easy access and they ship everywhere. The parts range available for so many euro models is amazing, it's truly a one stop shop. Plus the quality is what keeps me coming back. I refer EUROEMPIREAUTO to all my car clubs and friends. Just call them and you'll see what I mean. Sam is the best and I want to say thank you to you and your team for everything you've done 👌🤙😎.

Amazing! Purchased carbon fiber revozport-style side skirt extensions to suit the vw MK7R side skirts. Very impressed with the build quality and fitment (images attached, checkout @sputnik_mkvii on ig for more). Packaging was really solid: wrapped in protective foam, and reinforced with wood. Great customer service too. Big thanks to the whole team! Definitely recommend these guys for your carbon fiber goodies.

As owner of eurocruisers Australia, a European carclub with 11,500 active members, i have been using AND recommending euro empire auto for a few years now, and apart from the odd "Australia Post" slow delivery which is beyond thier control, i have had zero negative feedback, but more importantly, fitment on products is on point. Sam, the owner is also very active with my carclub, which puts on charity cruise events all over Australia raising money for heartkids foundation ❤️ If you're in the market for an upgrade for your car, don't hesitate.

MK6 GTI CARBON ASPEC GRILLE The team over at euro empire auto have done an amazing job with my new carbon grille and the process of making it and shipping was phenomenally quick it took about 2-3 weeks to make and 3 days to ship. The quality with the grille sits flush and bolts up directly as would a stock grille no need to fiddling around just straight on. I highly recommend anyone looking at getting carbon for their European car to get it off the team, you will not regret your decision.

Euro auto Empire helped me equip my M240i with a number of parts, like carbon mirror caps and badges, among others all these parts are seamless and staff at the shop took care of Installation. Usually I’d see some faults from other shops installing these kinds of parts but my experience with Euro auto empire was quick and painless leaving me with nothing to complain. I’m looking forward to exploring more options for my car with this group.
