Yeedercar Rear Diffuser in Carbon Fiber for BMW G20 M Sport Sedan (2019)

It replaces the plain lower valance on the BMW G20 M Sport Sedan (2019) with a finned diffuser that cleans up the airflow leaving the rear bumper.

The clear coat is UV-stabilised, so the weave stays dark instead of fading to a chalky yellow under summer sun.

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

Fits: BMW G20 M Sport Sedan (2019)

Moulded from the BMW G20 M rear bumper profile so the outer edges meet the bumper corners cleanly.

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.

• 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)

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.

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.

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.

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.

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: diffuser, screws, clips and a fitment card.
