Gloss Black Rear Valance Insert for BMW F32 4 Series Coupe M Sport 2013-2016 by Maxton Design

Give your BMW F32 a sharper, more purposeful tail with this Maxton Design rear lower bumper add-on in high gloss black. Engineered for the M Sport rear bumper on the 2013, 2014, 2015 and 2016 4 Series Coupe, this sleek rear skirt section sits beneath the bumper and brings a clean, motorsport-inspired finish without fins or strakes for a smooth, modern look.

Made from tough, TUV-certified ABS, this rear under spoiler delivers the ideal blend of strength and flexibility, perfect for daily use and show cars alike. The deep piano black surface enhances the factory body lines and pairs perfectly with other exterior upgrades. Often searched as a rear undertray, rear apron, lower diffuser piece or bumper lip, this is a premium styling upgrade that transforms the back end of the F32.

We have supplied and fitted this exact piece on customer cars and our own builds, and feedback has been consistently excellent. Fitment is precise, the finish is superb, and the updated stance looks right at home on an M Sport Coupe.
