The 2021-Up BMW G82 M4 Extended Carbon Fiber Rear Trunk Spoiler is a high-performance accessory designed specifically for the BMW G82 and G83 M4 models. It is part of the Factory Extended Package offered by BMW. This rear trunk spoiler is constructed using premium carbon fiber material. Carbon fiber is renowned for its lightweight yet strong properties, making it an ideal choice for automotive components. The carbon fiber construction not only adds a touch of sportiness and sophistication but also contributes to improved aerodynamics and overall performance.

The package includes a single rear trunk spoiler, custom-designed to fit the BMW G82 and G83 M4 models. The spoiler is exquisitely finished in carbon fiber, showcasing its high-quality and performance-oriented nature. Its sleek and aerodynamic design complements the vehicle's overall aesthetics, enhancing its sporty and aggressive appearance. In addition to its visual enhancements, the Extended Carbon Fiber Rear Trunk Spoiler serves a functional purpose. It aids in reducing lift and increasing downforce on the rear of the vehicle, promoting better stability and improved handling during high-speed driving. This assists in optimizing the M4's performance potential and enhances driver confidence on the road or track.
