The mounting points line up with the factory lower bumper fixings on the Mercedes-Benz CLS400 C257 CLS-Class.

Each part is laid up by hand, cured under pressure, then trimmed on a CNC so the mounting edges sit flush.

It fixes from underneath with the supplied screws and clips; removing the rear bumper is not necessary on the Mercedes-Benz CLS400 C257 CLS-Class.

If your car has a factory tow bar, the diffuser may need trimming around the mounting bracket.

Standard output is gloss clear coat over 3K twill, but matte, satin, forged carbon and tinted clear coats (including red and blue) are all available at order time.

• Gloss, matte, satin or forged carbon finish
• 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

This is made in our own plant in Foshan, Guangdong rather than bought in and re-sold, which is why we can take a custom order and still quote a factory price.

Each part is weighed and measured against the master sample, then wrapped in foam and boxed in a double-wall carton with the hardware bagged separately.

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.

Wash with a soft mitt and a pH-neutral shampoo, and avoid abrasive polishes or machine compounds that cut through the clear coat.

Production is 10-15 business days because the part is made after you order it, not pulled off a shelf; after that it ships with tracking and a 12-month defect warranty.

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