Audi B9.5, RS4 Carbon Fibre AE Style Front Lip

Audi B9.5, RS4 Carbon Fibre AE Style Front Lip

Drop the nose of your RS4 Avant with the AE Style Carbon Fibre Front Lip, a full-width splitter that follows the lower edge of the bumper and turns up into a winglet at each outer corner.

Manufactured from dry carbon fibre with a high-gloss twill finish, the lip is a single moulding that locates on the factory mounting points. Three vertical supports brace it back to the bumper, and the upswept corner winglets carry the line towards the wheel arches.

It is the most effective single change to the front of a B9.5 RS4, and it pairs with the matching AE Style parts across the range.

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.

Upswept Corner Winglets

Each end turns up into a winglet that carries the line towards the wheel arch, framing the front of the car.

Single Piece Construction

Supplied as one moulding rather than a multi-piece kit, so there are no joins across the front of the car.

Pre-Drilled Mounting Points

Mounting tabs are formed into the moulding at the factory locations, so the part locates against the bumper 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

Lowered Front Stance

Visually drops the nose of the car and sharpens the leading edge without altering ride height.

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 B9.5 RS4 Avant (2020+)

Designed for the facelifted B9.5 RS4 front bumper. The pre-facelift B9 uses a different bumper and is not covered.

The standard A4 and S4 use a different bumper and are not covered.

Please Note

Professional installation is strongly recommended.

Ground clearance is reduced. Take care on steep driveways, speed humps and kerbs.

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.
