Second Hand BMW M4 Wheel Arch Liner

The BMW M4 has run across two main generations: the F82 (2014–2020) and the G82 (2021–present), and arch liners are not interchangeable between these two generations as the bodyshells are completely different. Within the F82 generation there were no significant body-style changes to worry about, and similarly the G82 has remained consistent in shape. If you are shopping close to the 2020–2021 changeover, confirm the exact generation with the breaker against your registration before ordering.

Yes, the BMW M4 has wheel arch liners (also called inner wing liners or splash guards) fitted to all four wheel arches on all variants, including both the F82 and G82 generations. They are standard fitment regardless of engine specification or drivetrain option, so every M4 that left the factory will have had them. Used examples are readily available from breakers, and you should quote your registration when requesting a match.

Trim level does not affect arch liner fitment on the BMW M4; a liner from a Competition model will be the same pressing as one from a standard M4 of the same generation. You may find minor cosmetic differences such as paint markings or bracket clips that vary between build dates rather than trim levels, but these do not affect whether the part fits. Confirm the generation (F82 or G82) and which corner you need (NS front, OS rear, etc.) and trim is not a concern.

The M4 (coupé) and M3 (saloon) share the same platform within each generation — F80/F82 and G80/G82 respectively — but because they are different body styles the rear arch liners in particular are unlikely to be identical. Front arch liners may have a higher chance of being shared given they sit ahead of the body-style differences, but this is not guaranteed. You should confirm cross-model fitment with the breaker against both registrations rather than assume they interchange.

Both a 2016 and a 2019 BMW M4 are F82-generation cars, so they share the same bodyshell and arch liner design in principle. However, there can be mid-production pressing or bracket changes that are not always publicly documented, so while fitment is generally expected to be compatible, it is worth asking the breaker to cross-reference both registrations to be certain. This is especially worthwhile for the rear liners, which tend to have more mounting points than fronts.

You need to specify both the side — nearside (NS, the kerb/left side) or offside (OS, the driver's/right side) — and whether it is a front or rear liner, as all four are different parts. On the M4 the rear liners are particularly distinctive and will not swap front-to-back. Give the breaker your registration, the corner required, and the generation (F82 or G82) to get an accurate quote.
