Audi S4 B9 A4 Sline Carbon Fiber Front Lip (2019) | Hand-Laid Carbon Weave

A front splitter for the Audi S4 B9 A4 Sline Lip (2019) that turns the standard front bumper into something closer to the factory aero pack, without swapping the whole bumper.

The clear coat is UV-stabilised, so the weave stays dark instead of fading to a chalky yellow under summer sun.

Fitting is a two-person job: offer it up with tape in place, check the gaps left and right, then drive the self-tapping screws home through the pre-marked positions.

The mounting tabs follow the factory bumper contour of the Audi S4 B9 A4 Sline, so it lines up with the original fixing points.

Sport and standard bumpers on the same model can sit at different heights – compare the photos with your own bumper before ordering.

Weave, finish and edge treatment are all chosen when you order: glossy 3K twill is the default, while matte, forged carbon, coloured clear coat and carbon-kevlar hybrids are produced on request.

• Logo application or badge cut-outs on request
• Gloss, matte, satin or forged carbon finish
• 3K twill, 6K twill, plain weave or carbon-kevlar hybrid
• Coloured tinted clear coat (red, blue, yellow)

A ceramic or wax coat once a season is all this needs – the clear coat handles UV, but it is not a scratch-proof layer.

Quality control is a visual inspection plus a fit check on the master jig; anything with a lifted clear coat or a distorted mounting edge is rejected rather than shipped and discounted.

Because the tooling is in-house, changes that a trader would refuse – a different weave, a logo under the clear coat, a slight trim to clear a roll cage – are normal work for us.

Small runs are quoted per piece; above roughly 50 pieces the tooling cost is absorbed and the unit price drops, so ask for a stepped quote.

Allow 10-15 business days for production plus transit time; express DHL, UPS and FedEx options are available at checkout, and the part carries a 12-month warranty against manufacturing defects.

In the box: lip, pre-applied 3M VHB tape, stainless self-tapping screws and a fitment card.
