Used BMW M4 Flywheel

Yes, but only on manual gearbox variants — the M4 has been offered with both a 6-speed manual and a dual-clutch automatic (DCT on F82 generation, 8-speed torque-converter automatic on G82 generation), and a traditional flywheel only exists in the drivetrain of the manual versions. Automatic variants use a flexplate (driveplate) instead, which is a different part entirely, so if your M4 is an automatic you need to search for a flexplate or driveplate, not a flywheel. If you are unsure which gearbox your car has, your V5 or a VIN check will confirm it before you request quotes.

Both years sit within the F82 generation (2014–2020), share the S55 3.0-litre twin-turbocharged inline-six engine code, and are both available with the 6-speed manual, so on paper the flywheel is likely to be the same unit. However, there were mid-production ancillary and mounting detail changes across the F82 run that are difficult to verify without checking part numbers, so you should confirm the specific part against your registration with the breaker before buying. Supplying your engine code from your V5 gives the breaker the best chance of matching it correctly.

The F82 (2014–2020) uses the S55 engine and the G82 (2021–present) uses the S58 engine — these are different engine families with different flywheel specifications, so the parts are not interchangeable across that generation boundary. Even if both cars happen to have a 6-speed manual, the flywheel is matched to the engine and gearbox bell-housing, both of which changed between generations. Always quote both your generation and engine code to the breaker to avoid being sent the wrong unit.

For the flywheel specifically, the Competition trim does not introduce a different engine — both standard and Competition M4s within the same generation share the same engine code (S55 on F82, S58 on G82) — so the trim level itself does not affect flywheel fitment. What matters is your engine code, gearbox type (manual only), and generation, not the Competition badge. Confirm the part number against your registration with the breaker as a final check, but do not be put off sourcing from a non-Competition car if the engine and gearbox match.

The F80 M3 and F82 M4 are both built around the S55 3.0-litre twin-turbo engine and the same 6-speed manual gearbox, making the flywheel a strong candidate for cross-model fitment within that generation. Because the underlying drivetrain components are shared between those two models, breakers frequently list them interchangeably. That said, confirm the specific part against both registrations with the breaker before purchasing, as production-run detail changes can affect fitment even between closely related models.

The single most useful piece of information is your engine code, which you can find on your V5 logbook or via a VIN check — this tells the breaker exactly which engine family and variant your car has, which is more reliable than the model year alone. You should also confirm that your car has a manual gearbox, since automatic M4s use a flexplate rather than a flywheel. Having your registration and mileage to hand will also help the breaker verify the part and give you an accurate quote through Findapart.
