Street Pro Rear Corner Extensions in Matte Black for BMW G80 M3
Give the back end of your G80 M3 the purposeful look it deserves with these genuine Maxton Design Street Pro rear corner extensions. These rear bumper add-ons are engineered specifically for the BMW G80 platform and add a sharper, lower stance without compromising the factory lines. Ideal for anyone searching for BMW G80 M3 rear corner splitters, rear bumper extensions, rear spats, rear arch splitters, rear lip extensions, or an aerodynamic styling upgrade for 2021 onwards M3 models.
Built from thick 10 mm ABS with a durable matte black surface, the Street Pro series is designed to cope with daily driving and spirited use. The material offers impressive impact and scratch resistance, while the UV-stable finish helps retain that deep black colour over time. Each piece ships with a protective film and an authenticity label so you know you are receiving the real thing.
Why enthusiasts choose Street Pro
- 10 mm ABS construction for solid rigidity and a premium, substantial feel
