If you like our performance style carbon fiber front lip for the BMW F32, F33 and F36 but want a more affordable option, then this Polypropylene (plastic) version is the one for you. Costing less than half of its CF counterpart, this front lip still offers a great styling upgrade from your stock M Sport bumper. It comes in a satin black finish but can easily be painted in gloss black or to paint match your 4 series. Being made of polypropylene (a very durable and lightweight plastic material) this lip is unlikely to crack and carries RW Carbon's fitment guarantee. These front lip spoilers fit all 428i, 430i, 435i and 440i w/ M Sport package. Each front lip comes with all the hardware required for install. If you have any questions please contact us.
