Audi S4 A4 B9 Carbon Fiber Rear Spoiler — Hand-Laid Carbon Weave, Fits Factory Mounts

Fits: Audi S4 A4 B9 — Hand Laid Carbon Weave, Fits Factory Mounts

It follows the boot edge radius of the Audi S4 A4 B9 —; on most cars a factory lip spoiler can simply be removed first.

Most owners fit this with the supplied automotive tape and no drilling; a heat gun or hairdryer makes the tape bite.

Each part is laid up by hand, cured under pressure, then trimmed on a CNC so the mounting edges sit flush.

Sedan, coupe and estate boots on the same model are different shapes; match the body style in the photos to yours.

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.

• Coloured tinted clear coat (red, blue, yellow)
• 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

This is made in our own plant in Foshan, Guangdong rather than bought in and re-sold, which is why we can take a custom order and still quote a factory price.

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.

The packaging is built for a journey, not a shelf: foam wrap, corner protection and a double-wall carton, so the part arrives as it left the bench.

Wash with a soft mitt and a pH-neutral shampoo, and avoid abrasive polishes or machine compounds that cut through the clear coat.

Because every piece is laid up to order, expect around two weeks in production before dispatch. Tracking is provided, and the 12-month warranty covers manufacturing defects such as de-lamination or a lifting clear coat.

In the box: spoiler, pre-applied automotive tape, an alcohol wipe and a fitment card.
