Two generations of BMW M3 — the F80 (2014–2020) and the G80 (2021–present) — are the most popular M cars among enthusiasts today. Both respond incredibly well to carbon fiber exterior upgrades, but for different reasons. Here's a generation-by-generation breakdown.
F80 M3: The Naturally-Turbocharged Classic
The F80 M3 was BMW's first turbocharged M3, and its relatively restrained styling makes carbon fiber upgrades highly visible. On the F80, carbon fiber parts like mirror caps, front lips, and diffusers pop visually because the car's otherwise conservative styling creates a strong contrast with the aggressive weave pattern.
Weight reduction is also more meaningful on the F80 — at 3,580 lbs, it's lighter than the G80, so every pound removed has a slightly more pronounced effect on performance.
G80 M3: The Wide-Body Statement
The G80 M3 is a bigger, bolder, more aggressive car — and carbon fiber upgrades suit its style perfectly. The G80's large grille, wide fenders, and pronounced bodywork make it look almost production-race-ready with the right carbon fiber additions. The grille replacement in particular is one of the most transformative single upgrades available for any BMW.
The G80 is heavier (around 3,800 lbs in base spec), which makes the case for weight reduction via carbon fiber parts even stronger — particularly on track cars.
Which Should You Upgrade First?
Both generations benefit enormously from carbon fiber. For F80 owners, start with mirror caps and a front lip. For G80 owners, the grille replacement and rear diffuser are immediate game-changers. See all F80/G80 M3 carbon parts →
