BMW F30/F31 M Sport Side Skirt Extensions
3 products
Every F30 side skirt extension here is made for cars with the M Sport side skirts. Each one screws on under the factory skirt as a carbon blade, so the M Sport part stays where it is.
You can choose a plain extension listed for the sedan and the wagon, a version made for the F31 wagon, or an M Performance-style pair that is also listed for the 4 Series and the F80 M3. All three are real carbon fiber with predrilled holes. See all F30 and F31 parts.
BMW F30/F31 M Sport Side Skirt Extensions buying guide
Check for M Sport side skirts first
The M Sport package gave the F30 and F31 their own side skirts, and all three extensions are shaped to sit under those. On a car without M Sport the factory skirts are a different shape, so an extension won't line up unless you convert to M Sport skirts first. If you're not sure which skirts your car has, text a side photo to 609-525-4865.
Choosing an F30 side skirt extension: plain or M Performance style
- F30/F31 M Sport extensions: listed for the sedan and the wagon from 2012 to 2019, which covers cars before and after the 2016 facelift. The listing gives no style name, so compare its photos with the other two.
- F31 wagon extensions: a separate listing named for the Estate, the UK name for the F31, which BMW USA sold as the 3 Series Sports Wagon. It is listed for 2013 to 2019 cars.
- M Performance-style extensions: follow the look of BMW's accessory extensions. Besides the F30, the listing names the F32, F33 and F36 4 Series with M Sport and the F80 M3, but not the M4. Its fitment starts at 2014, so owners of earlier sedans should ask before ordering. M3 owners can see it with the other F80 M3 side skirts.
Drilling and returns
Each set comes with predrilled holes and self-tapping screws, and the two M Sport listings say drilling is required, so have a body shop fit them. Hold the extensions up to the skirts and check the gaps before anything is drilled or painted: a drilled or installed part can't be returned. If a set doesn't fit the car named on its product page, tell us before installing and our fitment guarantee pays the return shipping. Finishing the back too? See the F30 and F31 diffusers.
Frequently asked questions
My F30 doesn't have M Sport. Can I still fit these extensions?
Not to the factory skirts. All three are made for the M Sport side skirts, and the skirts on other F30 and F31 trims are shaped differently, so you'd need to fit M Sport skirts first. Text a photo of the side of your car to 609-525-4865 and we'll tell you what you have.
Which extensions should I buy for an F31 Sports Wagon?
Two listings name the wagon: the F30/F31 M Sport extensions, sold for the sedan or the wagon, and the F31 Estate extensions made for the wagon alone. Both need the M Sport skirts. The M Performance-style pair shows under F30/F31 in our fitment data, but its title names only the sedan, so text us before ordering it for a wagon.
Do the M Performance-style extensions fit a 4 Series?
Their listing names the F32 coupe, F33 convertible and F36 Gran Coupe with M Sport, from 2014 to 2019. It also covers the F80 M3 but not the F82 M4, which has its own set. As on the 3 Series, the car needs its M Sport side skirts for the extensions to line up.
