A5 / S5

Audi A5 / S5 B9 and B9.5 carbon fiber parts

For the B9 and facelifted B9.5 Audi A5 and S5 there are two rear diffuser options, a front lip and canards, side skirts, a vented hood and mirror caps. All are prepreg dry carbon fiber and imported from leading manufacturers around the world.

Which part fits which version?

The front lip, rear diffuser and side skirts are marked B9 / B9.5 and are listed for both pre-facelift and facelifted cars. The V2 rear diffuser and the front canards are marked B9 only. If your car is a B9.5, ask on WhatsApp before ordering these two.

Front and rear bumper parts

The front lip mounts on the lower edge of the bumper and the front canards on its outer corners. At the back you can choose between two designs: the rear diffuser and the V2 rear diffuser. On a pre-facelift B9 both are options and the product photos show the difference; on a B9.5 the rear diffuser marked B9.5 is the one that fits. The side skirts mount along the sills below the doors.

Parts shared with the RS5 and A4

The vented hood has RS5 in its title, replaces the original hood and fits the RS5 too. The A4 hood is a separate product on the A4 / S4 page. The mirror caps fit the A5, S5 and RS5 and also the A4, S4 and RS4 B9; when you order, you choose whether your car has blind spot assist.

Frequently asked questions

Is there a front lip or diffuser for the RS5?

This page has none. The RS5 has different bumpers from the A5 and S5, so the front lip, canards and diffusers here are for the A5 and S5.

Are the parts the same for the Coupé, Sportback and Cabriolet?

Product titles do not separate body styles, and the standard and S line bumpers on the A5 are different as well. If you are ordering side skirts, a front lip or a rear diffuser, confirm the body style (Coupé, Sportback or Cabriolet) and the bumper type on WhatsApp before you order.

When will my part arrive?

Lead time for sourced-to-order parts is confirmed on WhatsApp right after your order. Parts ship via partner couriers, and every part comes with a 24-month BYC warranty against manufacturing defects.
