Mercedes-Benz W219 CLS-Class WI Style FRP Side Skirts 2005-2009

Upgrade the side profile and exterior styling of your 2005-2009 Mercedes-Benz W219 CLS-Class with these WI Style FRP side skirts. Designed to give the CLS a lower, sharper, and more performance-inspired appearance, this side aero upgrade enhances the vehicle’s long coupe-like body lines while maintaining a clean aftermarket fit.

This package includes one pair of WI Style side skirts designed for the W219 CLS-Class platform. The side skirts are shaped to follow the factory lower body geometry, helping create a more complete side profile when paired with front lips, rear diffusers, trunk spoilers, or other exterior styling upgrades.

Constructed from FRP, these side skirts provide a lightweight and finish-ready base for paint matching or custom exterior preparation. This upgrade is ideal for owners seeking a refined side-body enhancement for street, show, or styling-focused builds.
