Maxton Design Piano Black Rear Corner Extensions for BMW 3 Series G20 M Sport 2019 to 2022
Give your G20 M Sport saloon a sharper, lower and more purposeful stance with these Maxton Design rear bumper corner extensions. Finished in a deep, high-shine piano black, these rear corner spoilers complete the back end with a clean OEM plus look, tidying the edges of the valance and visually lowering the rear of the car for a more aggressive presence on the road.
Crafted from high quality ABS plastic, these rear bumper add-ons deliver the perfect combination of durability, light weight and flexibility. No painting is required. They arrive ready to install and are a brilliant value styling upgrade for the 2019, 2020, 2021 and 2022 BMW 3 Series G20 M Sport saloon.
