What Makes the Competition Different
Both the M3 and M4 Competition share the same 3.0-litre twin-turbo straight-six, producing 503bhp and 479lb ft of torque — a significant step up from the standard M3/M4. The M3 Competition is also available with M xDrive, BMW's first four-wheel-drive system fitted to an M3, added specifically to put the extra power down more effectively.

Every part in this range is autoclave-cured pre-preg carbon fibre — stiffer and lighter than the glass-fibre or ABS panels used in budget kits, with a weave that stays sharp and glossy rather than fading over time.

|---|---|---|
| DIY (single parts) | ~30–60 min each | Experienced fitters comfortable with trim and clip work |

Frequently Asked Questions
What's the power output of the M3/M4 Competition?
503bhp and 479lb ft of torque from the 3.0-litre twin-turbo straight-six, shared across both the M3 Competition and M4 Competition.
Is the M3 Competition available with four-wheel drive?
Yes — the M3 Competition xDrive was the first four-wheel-drive M3 in BMW's history, added to help put the car's power down more effectively.
Do the same carbon fibre parts fit both the M3 and M4?
Some parts are shared (like the front bumper ducts), but splitters, diffusers, and spoilers are model-specific — check the product page for confirmed M3 (G80/G81) or M4 (G82/G83) fitment.
Is this real carbon fibre or a carbon-look finish?
Genuine pre-preg carbon fibre, autoclave-cured — not a carbon-effect vinyl or ABS moulding.
Final Thoughts
The G80 M3 and G82 M4 Competition are already serious performance cars — genuine carbon fibre styling is the natural next step, with a full range covering the front, sides, and rear of both models.
