BMW G82/G83 M4 Side Skirts
4 products
Carbon fiber side skirts for the BMW G82 M4 coupe and G83 convertible: full trim replacements and Unit 17 extensions.
The right G82 M4 side skirts depend on the gloss-black trim along your sills: replace it with carbon, or keep it and add one of our extensions underneath. The replacements here are the M4 versions; sedan owners have their own on the G80 M3 side skirts page.
BMW G82/G83 M4 Side Skirts buying guide
Replacing the M4's gloss-black trim
For a full replacement, choose between the MP style with a winglet and the OEM style without one. The MP-style skirts are a one-to-one copy of the M Performance style part in dry carbon prepreg with a gloss finish, and they use the factory tabs and fixing points without drilling. The OEM style takes the place of the same detachable trim in pre-preg carbon but keeps a plainer profile. Both carry G82 M4 in their titles, so they're the ones to order for a G82 or G83.
Extensions for G82 M4 side skirts
If you like the factory trim, add carbon beneath it instead. Our V2 extensions are 100% pre-preg, come as a pair, bolt on and are offered in gloss or matte; select G82 M4 when you order. The extensions with a small winglet mount underneath with the supplied self-tapping screws through pre-drilled holes. Both are Unit 17 designs you won't find at other retailers, and neither removes your factory skirts.
All of these are listed for the G82 coupe and G83 convertible from 2021 on, which our fitment data counts as covering the 2025 facelift. Test-fit before painting or fitting: if a skirt doesn't fit the car named on its product page, contact us before installing and our fitment guarantee covers return shipping. More coupe parts are on the G82/G83 M4 page.
Frequently asked questions
Do M3 side skirts fit the G82 M4?
The full replacements don't cross over, so order the ones titled for the G82 M4 rather than the M3 versions. The extensions are shared: both are listed for the M3 and the M4, and the V2 asks you to pick G82 M4 at checkout so the right set is sent.
Which M4 side skirts have a winglet?
The MP-style full replacement has one, copied from the M Performance style part. Our small-winglet extension adds a flared tip to a blade that sits under your factory skirt. The OEM-style replacement has no winglet.
Can I get matte side skirts for my M4?
Yes, with the V2 extensions. The listing offers gloss or matte in pre-preg dry carbon and asks you to say which at checkout, along with your model. The MP-style replacement is listed with a gloss finish, and the other listings don't name one, so ask us if the finish matters.
