Audi A4 B9 Sline S4 Carbon Fiber Front Lip (2017-2020) | Hand-Laid Carbon Weave

It sharpens the lower front bumper of the Audi A4 B9 Sline S4 Lip (2017 2020), dropping the visual mass of the nose and giving the car the stance the factory left out.

Fits: Audi A4 B9 Sline S4 Lip (2017 2020)

Shaped from a scan of the Audi A4 B9 Sline S4 bumper rather than a generic blank, which is why the edges sit flush instead of standing proud.

The standard layup is 3K twill; 6K, plain weave and forged carbon can all be produced on request.

Most cars take 45-90 minutes with the wheels turned and the car on ramps; the bumper does not have to come off the Audi A4 B9 Sline S4.

If your car is lowered, check the approach angle on your driveway first: the lip hangs about 40-60 mm below the factory bumper.

Standard output is gloss clear coat over 3K twill, but matte, satin, forged carbon and tinted clear coats (including red and blue) are all available at order time.

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

The shop floor is in Shishan, Nanhai – the composite cluster west of Guangzhou – and the same bench that runs this part also runs our OEM work for tuners and distributors.

Each part is weighed and measured against the master sample, then wrapped in foam and boxed in a double-wall carton with the hardware bagged separately.

One piece is fine for a first sample – there is no minimum order. When you need volume, the same mould runs batches of 50, 200 or 1,000+ pieces.

Rinse road salt and brake dust off regularly and wipe with a pH-neutral cleaner; a light wax keeps the clear coat glossy and stops dust bonding to the weave.

Production is 10-15 business days because the part is made after you order it, not pulled off a shelf; after that it ships with tracking and a 12-month defect warranty.

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