Audi R8 4S Carbon Rear Diffuser

Audi R8 4S Carbon Rear Diffuser | Exclusive Genuine OEM Carbon Fibre Component

Secure this Audi R8 4S carbon rear diffuser, a genuine OEM carbon fibre rear bumper diffuser — an original Audi manufacturer part specific to the R8 4S (4S0 chassis). This Audi R8 4S carbon rear diffuser provides the model’s signature aerodynamic lower rear treatment in genuine factory carbon fibre, not an aftermarket reproduction.

This Audi R8 4S carbon rear diffuser is a visually prominent and aerodynamically functional component that defines the R8’s rear profile. Genuine OEM carbon fibre from Audi’s factory carries a weave quality, lacquer depth, and dimensional accuracy that aftermarket alternatives cannot match, produced using pre-preg carbon construction and UV-resistant automotive lacquer to the same tolerances as the surrounding body panels.

The R8 4S was produced across two distinct generations — the original 4S series (2016–2019) and the facelifted 4S series (2020–2023) — with subtle differences in rear bumper and diffuser geometry, and the standard R8 4S and R8 4S Performance use different rear bumper assemblies with different diffuser configurations. Please contact us with your VIN or model year and specification (standard/Performance, pre-facelift/post-facelift) to confirm the exact part number.
