Transform the rear of your F30 saloon or F31 touring with a premium rear valance that delivers a true motorsport look. This twin-exit rear lower bumper insert features genuine carbon weave with a deep gloss finish for that factory-plus appearance enthusiasts want. Crisp contours, sharp fins and precise moulding give your 3 Series a purposeful stance while retaining an OE-style fit.

Built from real carbon, not plastic or hydro-dip, this rear diffuser insert is clear coated for UV resistance and long-lasting shine. We have installed this upgrade on customer cars and the feedback has been consistently excellent for fit, finish and the aggressive styling it adds.
