Side Skirts Extension Compatible with 2019-2025 BMW G20 G28 3 Series 330i M340i M Sport, CMST Style Rocker Panel Lip Splitter Spoiler ABS Gloss Black, 2PC

Material and finish are handled in a single step: high-grade ABS plastic is shaped under pressure and finished with a piano-gloss black paint process that arrives coat-ready out of the box. There's no sanding, priming, or color-matching required. The gloss black pairs naturally with M Sport bumpers and factory shadowline trim, and holds up against road debris and minor flexing better than cheaper PU foam alternatives.

Installation uses a dual-attachment method — 3M automotive adhesive tape for surface bonding and self-tapping screws for structural hold — giving you a more secure mount than tape-only kits. Instructions aren't included, so a body shop visit is the recommended route for anyone who wants flush panel alignment and a clean screw-hole finish. The kit ships as a complete two-piece set with all hardware in the box.

For G20 owners who want the visual aggression of a full aero kit — wider stance, lower visual center of gravity, sharper side profile — without the cost of a carbon fiber package, these skirts are a direct, no-compromise starting point.
