Audi A3 S line / S3 8V Sedan Carbon Fiber Side Skirt Extensions, 2014–2019

Carbon Fiber Side Skirt Extensions for Audi A3 S line / S3 8V Sedan

Add a gloss carbon-fiber accent along the lower sides of your sedan. These extensions mount to the existing side skirts rather than replacing the complete rocker panels, making them a styling companion to a separately purchased carbon-fiber front lip or rear diffuser.

Listed Vehicle Fitment

• Audi A3 8V S line Sedan.
• Audi S3 8V Sedan.
• Body style: 4-door Sedan.
• Source-listed years: 2014, 2015, 2016, 2017, 2018 and 2019.
• Not for Audi A3 Base models.

The A3 Base exclusion does not by itself exclude an S3 carrying a regional “Base” trim designation. Confirm VIN, production date, regional model year and actual side-skirt profile before ordering. The source combines years and models without a verified market-specific application table; check the 2014 application and any pre-facelift/facelift trim differences individually.

Existing hidden fitment entries extend to 2020, but the detailed application ends at 2019. Those entries do not establish 2020 fitment. Sportback/Hatchback, Cabriolet, RS3, other platforms, aftermarket skirts and conversion bodywork are not confirmed applications.

Material and Finish

• Specified carbon material: 3×3 weave carbon fiber.
• Construction described as carbon fiber reinforced with a glass-fiber composite.
• High-gloss lacquer and a double-layer anti-UV clear-coat finish; the source also describes polishing and wax sealing.

This reinforced construction is not presented as pure carbon or confirmed dry carbon. Exact laminate composition, dimensions and measured component weights are not supplied. No aerodynamic test data is provided, so downforce, handling or fuel-economy improvements are not promised.

Package and Mounting Supplies

The listing identifies side skirt extensions and included self-tapping screws. Exact left/right contents, molded piece count and screw quantity are not itemized. Plural wording does not independently confirm a two-piece pair. Verify the actual package contents before ordering.

Tape, additional clips and brackets are not listed as included. The generic reference to supplied hardware does not establish additional specific fasteners. Complete side skirts, rocker panels, front lip and rear diffuser are not included in the stated listing.

Installation Guidance

Professional installation is recommended. Test-fit to the existing side skirts before drilling or fastening. Verify alignment along the intended mounting surfaces, door-opening clearance, wheel-area clearance and access to designated lifting points. Check whether original fasteners are retained or reused; detailed mounting-point instructions are not supplied.

Although the original introduction describes fitting without modification, self-tapping screws are explicitly listed. No-drill installation is therefore not promised. Have the installer determine suitable fastening locations and pilot-hole requirements, checking behind mounting surfaces for wiring, hoses and concealed equipment. Do not force the extensions onto mismatched skirts or assume tape-only retention.

Check secure attachment before driving and allow for reduced clearance over ramps, curbs and uneven surfaces. Do not use the extensions as lifting points or assume structural impact protection. Installation time depends on the actual vehicle and mounting requirements; no fixed time is promised.

Frequently Asked Questions

Do these replace the complete side skirts?
No. The source describes extensions mounted to the existing skirts.

Will they fit an A3 Base?
A3 Base models are explicitly excluded. Confirm the matching S line or S3 skirt profile.

Are they supplied as a left/right pair?
The exact quantities and sides are not itemized. Confirm the package rather than relying on plural wording.

What installation supplies are listed?
Self-tapping screws are included. Tape and additional brackets are not specified.

Is this pure dry carbon?
The source describes 3×3 carbon fiber with glass-fiber reinforcement, not a confirmed pure dry-carbon construction.
