Chief Keef’s BMW M5 Returns from Tuning Shop with Wild Carbon Styling and Stage 2 Mods

Chief Keef apparently decided the latest BMW M5 did not attract enough attention in factory form. So the American rapper handed the sedan to a tuner and ended up with something far more aggressive once the work was finished.

The project belongs to the artist born Keith Farelle Cozart, better known through names like Sosa, BigGucci Sosa, Almighty So, Turbo, and Otto. The 30-year-old rapper has remained active since 2008, and now his latest BMW joins the growing list of heavily modified G90-generation M5 builds appearing online.

According to the Instagram account @stars.in.the.ceiling, the sedan received a Stage 2 upgrade package. The setup includes a revised air intake arrangement, cat-less downpipes, and a different exhaust system. Output numbers were not disclosed afterward, which leaves some guessing room. Stock figures already stand at 717 horsepower and 738 pound-feet, or 1,000 Newton-meters, from the factory.

BMW claims the standard sedan reaches 60 mph in 3.4 seconds. Pricing in the United States starts at $123,300 MSRP, while the Touring variant sits at another $2,000 higher. The mechanical work was only part of the transformation.

Inside, the cabin now features a multi-color starlight headliner displaying the M5 logo overhead. Black and orange leather covers most of the interior surfaces, mixed with carbon fiber trim and extra plastic elements mentioned in the source. Loud combination. Then again, subtle styling never looked like the goal here.

Outside, the sedan wears a full body kit from an unnamed tuner. The article hints that Mansory involvement seems possible because several exterior additions resemble parts associated with the German company. No confirmation exists, though.

The visual package adds extra sections around the front bumper, together with reshaped outer grille edges. A new hood sits up front, too, and the design leans heavily toward exaggerated sculpting. Side skirts stretch along the lower profile between both axles, while the rear gains a chunky diffuser and a larger ducktail spoiler.

Most of those exterior components use a forged-carbon appearance. The contrast works against the green paint finish covering the rest of the car. The article even questions whether the green surface might be a wrap rather than paint. Black wheels complete the setup, although their design stays relatively close to the original factory style.

Not everybody likes the newest BMW M5. The source itself claims many enthusiasts view the latest version as slower and less attractive than the previous generation. Yet modified examples continue appearing at a rapid pace, and Chief Keef’s build now ranks among the more difficult ones to ignore.
