Audi S3 2014–2019 / RS3 2017–2019 Sedan Carbon Fiber Side Skirt Extensions

Carbon Fiber Side Skirt Extensions for Audi S3 / RS3 Sedan

Add a gloss woven-carbon accent along the lower sides of your Sedan. These extensions are described as mounting to the existing side skirts, complementing other exterior accents without being presented as replacement structural rocker panels.

Model-Specific Fitment

• Audi S3 Sedan: 2014–2019.
• Audi RS3 Sedan: 2017–2019.
• 8V / 8V.5 platform naming appears in the original product title; verify the actual vehicle and original side-skirt profile.

The source's detailed fitment list also shows “(2020)” for both models, while the main description and original title end at 2019. Treat 2020 as requiring separate confirmation, not established fitment. The combined original 2014–2019 title does not mean RS3 Sedan compatibility starts in 2014.

Confirm the VIN, production date, market, Sedan body style and mounting surface before ordering. Check pre-facelift and facelift skirt profiles individually; a combined generation label does not establish identical interfaces. No drivetrain-specific fitment map is supplied. A3, A3 S Line, Sportback, Hatchback, Convertible and other generations are not established applications in this item's source.

Material and Finish

• Source-specified 3×3 weave carbon fiber.
• Glass-fiber composite reinforcement described in the construction.
• High-gloss lacquer finish, with hand and machine polishing described.
• Source-described double-layer UV-protected clear coating.

The source also uses clear-coat/wax terminology without a separate coating-system specification. The UV-protection description is not a guarantee of permanent gloss or freedom from fading. No dry-carbon, prepreg, resin chemistry, carbon percentage, laminate thickness or measured net-weight specification is supplied.

Source-described development includes 3D design, CNC molding and trial installation on a vehicle. These process descriptions do not guarantee fit on every market specification or modified vehicle. No test results substantiate improved downforce, reduced drag, handling gains or quantified weight savings; the extensions are presented as exterior styling accessories.

Installation Scope and Included Attachment Materials

The source describes these as add-on extensions mounted to the existing side skirts, not a confirmed full replacement skirt assembly. Verify the original skirts and underside contact areas before installation.

• Self-tapping screws are listed as included.
• Adhesive tape is listed as included.

Exact physical piece count, left/right packing breakdown, fastener sizes and quantities, tape specification, brackets and pre-drilled mounting locations are not documented. Do not infer a two-piece package from the plural product name. Confirm the supplied parts and attachment layout before work begins.

Professional Installation Guidance

1. Inspect the existing skirts, underside and supplied extensions. Trial-fit before drilling or removing tape backing, checking the full contact area, end alignment and door clearance.
2. Use suitable vehicle support and preserve access to the designated jacking points. These extensions are not steps, lifting points, structural sills or load-bearing supports.
3. Clean and dry the contact surfaces with products compatible with the vehicle finish and actual tape. Follow the tape manufacturer's temperature, application-pressure and curing requirements.
4. Verify approved screw locations and the substrate behind each fixing point. Avoid wiring, lines, protected cavities and structural components. Self-tapping screws do not establish a no-drilling installation; no drilling template, pilot-hole specification or torque values are supplied.
5. Use the verified fastening method. Tape alone is not a substitute for required mechanical retention, and the source does not confirm that tape is pre-applied.
6. Check secure attachment, door operation, ground clearance and service access before driving. Reinspect periodically and after washing, impact or underside work.

Professional installation is recommended. The original no-modification and one-hour installation wording is not retained as a universal guarantee. Do not force a poorly fitting composite part into position or drive with loose, cracked or dragging extensions.

Care

Clean with a soft cloth and non-abrasive products compatible with the gloss coating. Avoid aggressive solvents and close-range high-pressure water at attachment edges. Follow the actual tape's curing and washing restrictions. Check for loose fasteners, lifting edges, laminate damage and changes to the coating.

Frequently Asked Questions

Does the RS3 fitment begin in 2014?
No. The source separately lists RS3 Sedan from 2017–2019; S3 Sedan is listed from 2014–2019.

Is 2020 confirmed?
The detailed list includes 2020 in parentheses, conflicting with the main 2019 end year. Verify that application separately before ordering.

Will these fit a Sportback or A3 S Line?
Those applications are not established by this item's Sedan-specific source.

Are these dry carbon?
Dry-carbon construction is not specified. The source describes carbon fiber with glass-fiber reinforcement.

Do they replace the factory side skirts?
The source describes extensions attached to the existing skirts. Confirm the actual interface and original trim requirements.

Are screws and tape included?
Both are listed, but their quantities and specifications are not itemized.

How many pieces are included?
An exact physical piece count is not supplied. Confirm the packing breakdown.

Is installation guaranteed to require no drilling?
No. Self-tapping screws are listed, but the drilling and fastening procedure is not specified.
