Honda Civic 10TH Carbon Fiber Rear Diffuser (2016-2018): Hand-Laid Carbon Weave Replacement

It replaces the plain lower valance on the Honda Civic 10TH (2016 2018): Hand Laid Carbon Weave Replacement 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: Honda Civic 10TH (2016 2018): Hand Laid Carbon Weave Replacement

Moulded from the Honda Civic 10TH : Hand 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)

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.

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.
