BMW G20 Body Kit – 3 Series G21 M Performance Style Front Splitter, Side Skirts & Rear Diffuser, Gloss Black (2019+)
Upgrade your BMW 3 Series G20 or G21 with this complete gloss black BMW G20 body kit — a front splitter, side skirt extensions, and rear diffuser in one aggressive, colour-matched package. Built in the M Performance design language, it gives your car a lower, wider, more planted stance the moment it's fitted.
Why This BMW G20 Body Kit Fits Your Car
This kit is engineered specifically for G20/G21 M Sport bumpers (2019+), bolting straight onto existing mounting points with no cutting required. The deep gloss black finish is styled to complement factory trim while adding a sharper, sportier edge, and the durable ABS construction stays lightweight, flexible, and chip-resistant for everyday use. Everything arrives in one box for a full stance transformation — front lip splitter with corner extensions, side skirt blades, rear diffuser, and all mounting hardware included.

Really pleased with this. The ABS plastic feels solid and thick, not the flimsy stuff you get elsewhere. Would buy from KEUBE again.
Fitment was spot on. Mounting points matched up first time, dead easy. Came well packaged with no scuffs or damage in transit. Five stars from me.
Fitted this at the weekend. Lined up perfectly with the factory mounting points, no drilling needed. The finish is deep and glossy, a real head turner. 10/10, exactly as pictured.
Great addition to the car. Needed a tiny bit of adjustment but nothing major. Would buy from KEUBE again.
Been after the M Performance look for ages and this nailed it. Sturdy and well moulded, no warping at all. Needed a tiny bit of adjustment but nothing major. Really happy, car looks mean now.
