Audi B9/B9.5, RS5 Carbon Fibre Rear Trunk Spoiler

Audi B9/B9.5, RS5 Carbon Fibre Rear Trunk Spoiler

Finish the rear of your RS5 Coupe with this Carbon Fibre Rear Trunk Spoiler, a full-width ducktail that follows the boot lid line and turns up sharply at each corner.

Manufactured from carbon fibre with a high-gloss twill finish, the spoiler is a single moulding shaped to the contour of the B9 boot lid. The raised centre section and swept outer tips give the rear far more presence than the standard lip without moving to a full wing.

It suits an owner after the most effective single change to the back of the car, and it fits both the pre-facelift B9 and the facelifted B9.5.

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.

Full Width Ducktail Profile

A raised centre section with swept outer tips, following the boot lid line across its full width.

Direct Boot Lid Fitment

Shaped to the contour of the B9 boot lid so it sits flush without packing or trimming.

Covers Both Generations

The boot lid carried over unchanged at the facelift, so one part fits the B9 and the B9.5.

High Gloss Twill Finish

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

Please Note

Professional installation is strongly recommended.

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.
