Audi C8, RS6/RS7 Carbon Fibre V.2 Rear Diffuser

Audi C8, RS6/RS7 Carbon Fibre V.2 Rear Diffuser

Rebuild the rear of your RS6 or RS7 with the V.2 Carbon Fibre Rear Diffuser, a multi-piece assembly with deep vertical strakes across the centre and a pair of separate corner blades carrying integrated red reflectors.

Manufactured from dry carbon fibre with a high-gloss twill finish, the main diffuser replaces the factory valance and wraps around both exhaust outlets. The corner blades mount separately at each end, extending the treatment out towards the rear quarters.

It is the more aggressive of the two C8 diffuser styles we carry, and the natural partner to a carbon front lip and side skirts.

Key Features

Dry Carbon Fibre Construction

Manufactured using a dry carbon process, chosen for its rigidity and the depth of its finish under direct light.

Multi Piece Kit

Supplied as the main diffuser plus a pair of corner blades, so the carbon carries across the full width of the rear.

Integrated Red Reflectors

Each corner blade carries a red reflector insert, echoing the factory rear light treatment.

Wrap Around Exhaust Surrounds

The diffuser body wraps around both exhaust outlets rather than stopping short of them.

Pre-Drilled Mounting Points

Mounting tabs are formed into the moulding at the factory locations, so the part locates against the bodywork without fabrication.

High Gloss Twill Finish

A clear gloss finish over a consistent twill weave, matched to the look of factory Audi Sport carbon components.

Performance Benefits

Transformed Rear End

Replaces the largest plain surface at the back of the car, making it the most significant exterior change available at the rear.

Improved Aerodynamic Profile

Designed to complement the aerodynamic profile of the car and help manage airflow around it.

Lightweight Exterior Upgrade

Carbon fibre construction keeps the added mass minimal.

Completes Your Carbon Fibre Build

Matches the weave and finish of the rest of the Proven Performance Parts Audi carbon range for a consistent exterior package.

Vehicle Fitment

Audi C8 RS6 Avant (2020+)

Audi C8 RS7 Sportback (2020+)

The standard A6, A7, S6 and S7 use a different rear bumper and are not covered.

Please Note

Professional installation is strongly recommended.

The factory rear valance is removed. This is a replacement panel, not an overlay.

The corner blades mount separately and require care to position symmetrically.

Parking sensors, where fitted, are transferred from the original valance.

Minor preparation, alignment or adjustment may be required during installation to achieve optimal fitment.

Due to the nature of carbon-fibre manufacturing, slight variations in weave pattern may occur between products.
