It follows the boot edge radius of the BMW G80 M3 G83 M4; 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.

Vacuum-bagged carbon fiber, autoclave cured, then finished with a UV-stable clear coat that resists yellowing in strong sun.

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

• 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.

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

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