Yeedercar Handcrafted Carbon Fiber Rear Diffuser for Audi RS3 Base Sedan 4-Door (2017-2019)

Fitted to the Audi RS3 Base Sedan 4-Door (2017-2019), it hides the underside of the rear bumper and adds the motorsport look the standard car lacks.

The mounting points line up with the factory lower bumper fixings on the Audi RS3 Base.

It fixes from underneath with the supplied screws and clips; removing the rear bumper is not necessary on the Audi RS3 Base.

Autoclave curing means the part keeps its shape in heat – no sagging on a hot day or after a track session.

If your car has a factory tow bar, the diffuser may need trimming around the mounting bracket.

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

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.

If you are a distributor, we can ship on your documents and hold stock under your SKU rather than ours.

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.

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.

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: diffuser, screws, clips and a fitment card.
