Audi S3 / A3 / RS3 8V | Prepreg Dry Carbon Fiber Side Skirt

Audi S3/A3/RS3 8V (2012-2020) Prepreg Dry Carbon Fiber Side Skirt

Engineered for Audi S3 8V, A3 8V and RS3 8V (2012-2020) owners, this Prepreg Dry Carbon Fiber Side Skirt set gives the side profile a race-inspired lower edge and visually drops and widens the car. Made to factory-spec tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this Audi 8V carbon side skirt set bolts directly to OEM mounting points and ships as a symmetric left + right pair.

Side skirts bridge the visual and aerodynamic line between the front and rear axles, cleaning up side airflow and visually completing the package with the front lip and rear diffuser. Character match is excellent with RS3 8V's 2.5 TFSI EA855 evo five-cylinder inline turbo engine (367-400 hp, legendary Audi five-cylinder sound) and S3 8V's 2.0 TFSI EA888 turbo (286-310 hp); for A3 8V it provides a tuning identity that separates from the OEM look. Autoclave-cured prepreg carbon technology delivers a noticeable weight reduction over wet lay-up.

Key Features

• Prepreg Dry Carbon Technology: Carbon plies cured in an autoclave under high heat and pressure for a more consistent weave.
• Aggressive Side Profile: Visually lowers and widens the car; integrates aerodynamically with front lip and rear diffuser.
• Lightweight: Noticeably lighter than factory plastic side skirts.
• Race-Grade Strength: Carbon fiber offers very high strength for its weight; resists stone chips.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under a high-gloss UV-protective clear coat.
• Direct OEM Fit: Mates to factory S3/A3/RS3 8V rocker panel clips and bolt points.
• UV & Environmental Protection: Long-life clear coat resists fading, road salt, and stone chips.
• Supplied as a Set: Left and right side skirts ship as a symmetric pair.

Prepreg Dry Carbon vs. Wet Carbon: Which Is Better?

Most aftermarket carbon parts are produced using wet lay-up, where resin is applied by hand and cured at room temperature. Prepreg dry carbon:

• Cured in an autoclave under high heat and pressure → a more consistent weave
• A controlled resin ratio → lighter and stronger
• The production method widely chosen in motorsport
• Minimal UV fading over years of use

Installation Notes

Installing the Audi 8V carbon side skirt set is a direct replacement of the OEM rocker. Professional installation is recommended:

1. Remove the lower clips and bolts along the rocker panel.
2. Carefully remove the OEM plastic side skirt; clean any residual double-sided tape.
3. Test-fit the carbon side skirt; check the front and rear fender transitions.
4. Secure using 3M VHB tape and supplied fasteners to the manufacturer's recommended torque.
5. Do not wash the vehicle for 24 hours; avoid high-pressure washing for 48 hours.

Care & Maintenance

Wash with pH-neutral car shampoo. Apply carbon-safe sealant every 6 months. Keep pressure washer nozzle at least 30 cm from the surface. Side skirts can be exposed to stone chips; periodic inspection is recommended.
