Fitment questions

What years of BMW M4 door will fit my M4?

The BMW M4 (F82 coupe, F83 convertible) ran from 2014 to 2020, and doors from any car within that generation should be compatible with yours. Always confirm the body style matches — coupe and convertible doors are not interchangeable. Check the side (NS nearside passenger, OS offside driver) when requesting a quote from the breaker.

Will a pre-facelift BMW M4 door fit a post-facelift M4?

The M4 F82/F83 generation ran from 2014 to 2020 and received a subtle refresh around 2017, but the door shell and frame remained the same throughout the generation. In practical terms, a door from a 2014–2016 car should fit a 2017–2020 car, but because you are crossing that production boundary you should confirm against your registration with the breaker before buying.

Does an M4 door fit a standard 4 Series (F32)?

The M4 F82 shares its basic platform with the 4 Series F32 coupe, and the door apertures are closely related, but there are known differences in panel detailing and fitment points between the M4 and standard 4 Series. Do not assume a straight swap — confirm with the breaker whether the specific door from the donor car will fit your M4 registration before purchasing.

Does the trim level affect which door I need — Competition versus standard M4?

No, trim level does not affect door fitment — a door from a standard M4 fits a Competition and vice versa, as the door frame and shell are identical across M4 variants. You may find cosmetic differences such as trim finishers or badging, but these do not affect whether the door physically fits. Colour is also not a fitment issue, as any door can be resprayed to match your car.

Does it matter which side the door is from?

Yes, absolutely — doors are side-specific and not interchangeable. You need to specify NS (nearside, passenger side, left) or OS (offside, driver side, right) when requesting a quote from a breaker. Getting this wrong means the door will not fit, so double-check before ordering.

What about the window regulator and electric features — will they match?

The door shell itself is what determines fitment, and the frame should fit regardless of which M4 variant the donor door came from. However, whether the regulator mechanism or any electric window or mirror features match your specific car can vary, so confirm those details against your registration with the breaker rather than assuming they will be identical.
