Home » 2020–2021 Audi S5 Sportback B9.5 Carbon Fiber Side Skirt Extensions with Rear Fins

Give your 2020–2021 Audi S5 Sportback B9.5 a more defined lower side profile with these carbon fiber side skirt extensions. Supplied as a left and right pair, the extensions follow the rocker area and finish with distinctive raised rear fins for a sharper, more pronounced side appearance.

These are vehicle-specific add-on side skirt extensions, not complete replacement rocker panels. For additional upgrades for the same generation, browse the Audi A5 / S5 B9.5 parts collection.

Audi S5 Sportback Side Skirt Extensions

The kit consists of two long-profile side skirt extensions designed for the left and right sides of the vehicle. Each piece follows the lower rocker contour and incorporates a raised fin toward the rear, creating a clear visual difference from simpler straight-profile side skirt lips.

  • Left and right side skirt extension pair
  • Add-on construction
  • Raised rear fin design
  • Vehicle-specific long-profile shape
  • Visible woven carbon fiber surface
  • Gloss exterior finish

Raised Rear Fin Design

The rear section of each extension curves upward into a pronounced fin. This feature gives the kit a more distinctive profile than conventional flat side skirt extensions while maintaining a continuous shape along the lower side of the S5 Sportback.

Product measurements show an overall length of approximately 206.6 cm / 81.34 in per side, with the raised rear section reaching approximately 12.5 cm / 4.92 in.

Gloss Carbon Fiber Construction

The exposed surfaces show a visible woven carbon fiber pattern beneath a gloss finish. Close-up product images also show molded edges, shaped rear sections and dedicated mounting points along the underside of the extensions.

This page is specifically focused on the S5 Sportback carbon fiber side skirt extension application. Broader A5/S5 exterior upgrades can be found in the Audi A5 / S5 collection.

Add-On Installation

These side skirt extensions mount along the lower side skirt area rather than replacing the complete factory rocker panel. The product images show multiple pre-positioned mounting points along the underside for mechanical fastening.

Before final installation, test-fit both sides and confirm alignment with the factory rocker contour, front and rear mounting areas and the raised rear fins. Professional installation is recommended for accurate positioning and secure attachment.

2020–2021 Audi S5 Sportback Fitment

Designed for selected 2020–2021 Audi S5 Sportback B9.5 applications. Fitment should be confirmed by model year, body style and factory side skirt configuration before ordering.

This product should not be assumed to fit Audi A5, Coupe, Cabriolet or other B9/B9.5 configurations unless specifically confirmed. If you are unsure, send us your vehicle year, model and clear side-view photos through our Fitment Support page.
