West Coast Customs sharpens the 2026 BMW M5 with forged carbon

West Coast Customs has unveiled a refreshed 2026 BMW M5, giving the sedan a comprehensive makeover aimed squarely at a more aggressive look. The build centers on a vivid green paint set off by extensive forged-carbon elements applied to the hood, spoiler, side sills, and both front and rear bumpers. Complementing the package are a new diffuser and a vented hood. The result reads more track-leaning than boardroom-formal, a stance that flatters the M5’s proportions.

There’s no word on interior or mechanical changes, so the cabin likely stays stock and the powertrain untouched. For reference, the production BMW M5 uses a hybrid 4.4-liter twin-turbo V8 with a combined output of 838 hp and 1150 Nm, sprinting from 0 to 100 km/h in 3.4 seconds. It remains among the most powerful business-class sedans while still a full-size four-door, and this visual shake-up only sharpens that dual character.
