RSQ8 Carbon Rear Diffuser – Audi RSQ8 Carbon Fibre Rear Splitter Upgrade

Transform the Rear of Your RSQ8 with Purpose-Built Carbon

While the Audi RSQ8 already strikes a commanding stance, there’s always room to elevate its aesthetic with precision-crafted aero components. That’s where the RSQ8 carbon rear diffuser comes in. Meticulously designed to enhance both form and function, this dry carbon fibre diffuser adds race-inspired aggression while improving rear airflow.

More importantly, it completes the lower rear bumper with a sharp, dynamic finish that pairs flawlessly with OEM and aftermarket setups.

Precision-Made for the RSQ8 Platform

Because each RSQ8 has unique bumper curvature and sensor placement, this diffuser is molded specifically for the Audi RSQ8 (2020+). As a result, the fitment is exact, with no gaps or awkward overlaps.

Compatibility:

• Audi RSQ8 (2020-2024)
• Works with stock exhaust setup
• Parking sensors, cameras, and tow hook access remain unaffected

Although the diffuser looks dramatic, it blends seamlessly with factory lines and doesn’t compromise utility.

Tow Hitch Vehicles:

vehicles fitted with the optional electronic tow hitch from factory can still make use of their tow hitch as normal as we have made the centre section of our rear diffuser removable for an easy towing experience. See picture in our gallery.

PLEASE NOTE vehicles fitted with the factory fitted tow hitch as an optional extra in the USA and Canada will not be able to install our rear diffuser unless you swap out to the rear crash bar for none tow hitch vehicles.

Install:

The rear diffuser is a direct replacement for the original factory diffuser using all the original mounting points, clip locations and PDC locations. We recommend getting a professional body shop to install all parts.

Constructed Using Authentic Dry Carbon Fibre

What sets this component apart from generic alternatives is its dry carbon fibre construction — a method used in motorsport to minimize weight and maximize structural integrity.

Key Material Benefits:

• 2×2 Twill Weave Dry Carbon
• Vacuum-sealed and cured for strength
• UV-stabilized gloss or matte finish
• No fiberglass core or excess resin

Because of this, the carbon weave is sharp and consistent, and the piece won’t yellow, bubble, or crack over time like cheaper overlays.

Why dry carbon matters in high-end aero

Functional Aerodynamics for Road or Track

Although the RSQ8 is a luxury SUV, it hides serious performance potential beneath the skin. This diffuser harnesses some of that energy by helping to:

• Direct high-speed airflow under the vehicle
• Reduce rear-end lift at high speeds
• Channel turbulence for greater stability
• Complement the shape of the factory underbody tray

Therefore, it’s ideal for RSQ8 owners who want performance-focused modifications without compromising ride comfort.

Visually Aggressive Yet OEM+

Unlike oversized aftermarket diffusers that look out of place, this RSQ8 carbon rear diffuser retains a refined presence. It doesn’t scream “aftermarket” — instead, it whispers “factory plus.”

Its design complements:

• RS bumper lines and mesh
• Black optics and carbon styling packages
• Carbon boot spoilers and side skirts
• Performance exhaust tips

Whether you’re building a fully carbon-themed RSQ8 or upgrading one piece at a time, this diffuser delivers continuity and class.

Pair with Other RSQ8 Carbon Upgrades

To create a fully cohesive carbon appearance, pair this diffuser with:

• RSQ8 Carbon Centre Rear Boot Spoiler
• RSQ8 Carbon Side Skirts
• RSQ8 Carbon Front Lip Splitter

When combined, these upgrades add texture, depth, and aerodynamic presence — turning your RSQ8 into a showstopper without losing daily drivability.

Why Choose This Diffuser Over Alternatives?

While plastic add-ons may offer a similar shape, they simply can’t match the durability, fitment, or finish of dry carbon. This RSQ8 carbon rear diffuser stands out for several reasons:

• Tailored specifically to the RSQ8 chassis
• Real dry carbon with a flawless finish
• Long-term resistance to weather and wear
• OEM mounting points for factory-like install
• Compatible with stock and upgraded exhausts

As a result, it’s trusted by Audi tuners, detailers, and enthusiasts alike who value performance and polish.
