Carbon Fiber Side Skirt for Audi A3/S3

Give your Audi A3 or S3 a lower, more aggressive side profile with carbon fiber side skirts. This is a clean exterior upgrade for Audi owners who want the side of the car to match a front lip, diffuser, hood, or lighting setup.

Will This Fit My Car?

These carbon fiber side skirts are designed for compatible Audi A3 and S3 applications. Before ordering, confirm your exact year, trim, platform, rocker panel shape, lower side mounting surface, and existing exterior modifications.

• Confirm your Audi A3 or S3 fitment before ordering
• Check rocker panel shape, side skirt mounting surface, and lower body condition
• Confirm compatibility with existing side skirts, wraps, PPF, mud flaps, or aero parts
• Test-fit both sides before drilling, trimming, coating, wrapping, or final installation
• Professional installation is strongly recommended

What Is Included?

Your order includes the selected carbon fiber side skirt set shown on this product page. Product images show the side skirt shape, carbon finish, and active listing components.

How Hard Is Installation?

Installation difficulty is moderate. Side skirts require careful left/right alignment, test fitting, secure mounting, and even positioning along the rocker panels.

Professional installation is strongly recommended. Do not drill, trim, coat, wrap, or permanently mount the side skirts until fitment has been confirmed on both sides.

Is This Plug-and-Play?

No. These are aftermarket carbon fiber side skirts, not guaranteed plug-and-play OEM replacements. Some installs may require drilling, trimming, adhesive, hardware adjustment, or professional fitment work.

What Should I Check Before Ordering?

• Your Audi model, year, trim, and platform
• Rocker panel condition and lower side mounting surface
• Ground clearance, ride height, driveway angle, and daily driving conditions
• Compatibility with existing aero, wraps, PPF, mud flaps, or prior repairs
• Installer experience with carbon fiber side skirts
• Factory-direct or made-to-order body parts cannot be canceled after 3 business days

What Makes These Side Skirts Different?

These side skirts visually lower the Audi A3/S3 and help connect front lip, rear diffuser, carbon hood, wheels, and lighting upgrades into one cleaner exterior package.

Best For Daily Drivers, Show Cars, or Track Builds?

Best for Audi street builds, show cars, weekend builds, and content cars. They can work on daily drivers when installed carefully, but lowered vehicles should be cautious around steep driveways, speed bumps, parking blocks, and road debris.
