Carbon Fiber Ducktail Spoiler for BMW 840i Gran F93 M8 Competition 2020 2021

It gives the boot lid of the BMW 840i Gran F93 M8 Competition 2020 2021 a cleaner trailing edge and a little more rear stability at motorway speed.

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

Warm the boot lid, clean it with IPA, dry-fit with tape, then press and hold – about 30-40 minutes start to finish.

Fits: BMW 840i Gran F93 M8 Competition 2020 2021

The underside is moulded to the boot curvature of the BMW 840i Gran F93 M8, so the tape line contacts the panel evenly.

Aftermarket paint protection film or a previous spoiler leaves a residue line – clean it fully or the new tape lifts at the ends.

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)

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.

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.

We are the workshop, not a reseller. Yeedercar runs its own composite shop in Shishan, Nanhai, Foshan – roughly 1,000 m2 with an autoclave, a dust-free paint booth, CNC trimming and vacuum-bagging stations, plus twelve engineers and technicians who average eight years on carbon.

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

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