BMW M340i, 330i & 320i G20 G21 LCI EVO-1 Gloss Black Rear Diffuser

Give your LCI 3 Series the profile it deserves. ZAERO's EVO-1 Side Skirts extend the factory rocker panels with a set of purposeful, low-slung blades that visually drop the car, tighten its silhouette, and tie the front splitter and rear diffuser together into one cohesive aero package.

Engineered in Germany and moulded from automotive-grade ABS, each skirt is finished in a wet-look gloss black that holds its depth under sunlight and complements every exterior colour in the BMW palette — from Alpine White to Portimao Blue. The design hugs the underside of the door with millimetre precision, following the LCI's updated body lines without interrupting them.

Built the way the factory builds Developed to OEM tolerances in a German production facility, the EVO-1 skirts use the same grade of ABS found on OE trim pieces. Expect consistent panel gaps, clean edges, and a finish that survives carwashes, kerbs, and seasons on the road.

Bolt-on simplicity Pre-taped with heavy-duty 3M automotive adhesive, the skirts mount directly over the factory rockers. No drilling, no cutting, no mechanic — a degreaser, a steady hand, and ten minutes per side is all it takes. Illustrated instructions are included.

Fully road-legal ABE / TÜV-certified for unrestricted use on public roads, so there's nothing to declare and nothing to worry about at inspection time.
