Yeedercar Carbon Fiber Rear Diffuser for Porsche Carrera 4S Coupe 2-Door (2019-2020)

It replaces the plain lower valance on the Porsche Carrera 4S Coupe 2-Door (2019-2020) with a finned diffuser that cleans up the airflow leaving the rear bumper.

It weighs a fraction of the steel or plastic original, without the flex you get from a thin fiberglass copy.

Fits: Porsche Carrera 4S Coupe 2-Door (2019-2020)

Moulded from the Porsche Carrera 4S rear bumper profile so the outer edges meet the bumper corners cleanly.

Undo the lower bumper fixings, offer the diffuser up, and re-use the original screws where the holes align – about an hour.

Quad-exit and single-exit cars use different cut-outs – confirm from the listing photos which bumper your car has.

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.

• 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
• Gloss, matte, satin or forged carbon finish

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.

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.

Every unit is checked against a photo checklist – pinholes, weave alignment, mounting-hole position and clear-coat flow – before it is packed.

OEM and private-label work is welcome: your part number, your logo, your packaging, with an NDA if you need one.

Made to order in our workshop, typically 10-15 business days before it ships worldwide with tracking, backed by a 12-month warranty against manufacturing defects.

In the box: diffuser, screws, clips and a fitment card.
