High Gloss Rear Corner Extensions for BMW 1 Series F20 F21 LCI 2015 onward, by Maxton Design

Give the back end of your BMW hatch a sharper, lower and more purposeful stance with these Maxton Design rear corner extensions. Precision made for the facelift F20 and F21 with the M Sport package, these discreet rear bumper add ons enhance the factory styling with a clean OEM plus look in piano black. The finish ties in perfectly with other Maxton aero parts, diffusers and side skirt extensions.

We have installed these on customer cars and our own demo vehicles. Fit and finish are spot on, alignment with the rear apron is excellent and once the protective film is removed the deep gloss looks premium. It is the ideal subtle styling tweak that makes a big visual difference without going over the top.
