Rennline Aerokit II Side Skirts - 996 – Fits Porsche 996

Product Details Give your 996 the factory motorsport look with Rennline’s Aerokit II–style side skirts. Developed directly from brand-new OEM Aerokit II components, these skirts replicate the original Porsche design while offering precise, repeatable fitment for street or track-driven cars. This kit is a direct replacement for Porsche part numbers 996 559 980 01 (left) and 996 559 984 03 (right), originally supplied as Aerokit II side skirts. Designed around a 996 GT3, the geometry and proportions are optimized for OE bodywork and integrate cleanly with the factory rocker panels. Each kit includes a complete hardware package that allows the skirts to be installed just like a factory Aerokit, using proper fastening points and support for long-term durability. The skirts can be run bare for a purposeful, track-inspired look, or prepped and paint matched to your exterior for a seamless OEM+ appearance.
