Cheap BMW M4 Differential

The F82 BMW M4 ran from 2014 to 2020, so both years sit within the same generation, which is a good starting point for compatibility. That said, confirm the engine code on both cars — all F82 M4s use the S55 straight-six, but ancillary and mounting changes can occur within a generation, so ask your breaker to check your registration against the donor unit before buying. Never guarantee fitment on a used part without that check.

The F82 M4 (2014–2020) and the G82 M4 (2021 onwards) are separate generations with different platforms and drivetrain architectures — the F82 uses the S55 engine while the G82 uses the S58, so these differentials are not the same unit. Fitment across this generation boundary is extremely unlikely, but confirm with your breaker against your exact registration to be certain.

BMW did not introduce a significant structural facelift to the F82 M4 in the way some models receive a mid-cycle refresh with mechanical changes, so the generation is broadly treated as 2014–2020 as a single run. However, minor specification changes can occur during any production run, so supply your engine code and registration to the breaker so they can match the correct differential for your build date.

The Competition trim does carry a different differential tune compared to the standard M4, so this is worth flagging to your breaker rather than assuming any F82 unit will drop straight in. Trim level does not affect the physical mounting in the way that engine code or gearbox type does, but confirming whether the donor car was a Competition model helps the breaker match the right unit to your car.

Yes — the F82 M4 was available with a six-speed manual or a seven-speed DCT (dual-clutch automatic), and the differential fitted to each can differ, so this is one of the key details to give your breaker alongside your registration. Always confirm your gearbox type and engine code upfront so the breaker can source a compatible unit rather than one that looks similar but may not match your drivetrain.

The F80 M3 saloon and F82 M4 coupe share the same S55 engine and were produced over the same period (2014–2020), meaning their drivetrains are closely related and differential compatibility is plausible. However, whether the exact units interchange depends on gearbox type and any build-date specification changes, so route this question to your breaker with both registrations rather than assuming a straight swap.
