Important fitment notice: Compatibility is determined by the body style and factory side-skirt shape, not only by the model name. This page is intended for the Audi S3 8Y Sedan. Do not assume compatibility with the Audi A3, Audi RS3, S3 Sportback or 2025+ S3 8Y.5 without separate confirmation.
Add-On Installation
These carbon fiber side skirt extensions install beneath the existing factory side skirts using the supplied mounting hardware. Test-fit both pieces before drilling or fastening, and confirm the left and right orientation before completing the installation.
During test fitting, check the alignment along the rocker panels, the front and rear wheel-side clearances, the door-area clearance and the available ground clearance. Professional installation is recommended for accurate positioning and secure attachment.
