BMW G90 M5 Side Skirts
3 products
G90 M5 side skirts in pre-preg carbon come in MP, SQ-A and SQ-B styles, all of them listed for the sedan.
BMW paints the M5's factory side skirts in body color, so carbon along the sills is one of the more visible changes you can make from the side. Choose the style first, then the mounting: SQ-A uses 3M tape, SQ-B uses the factory mounting points, and the MP listing doesn't say. The same designs are sold for the G99 M5 Touring.

MP, SQ-A or SQ-B: G90 M5 side skirts compared
The MP name refers to BMW's own M Performance carbon sill extensions for the new M5, and these are aftermarket skirts in that style. SQ-A and SQ-B are two other shapes. Their listings describe autoclave-cured pre-preg dry carbon, a 2x2 weave and a high-gloss clear coat that resists UV fading. Building a set? The MP and SQ-A skirts have lips with the same names on the G90 M5 front lips page, while SQ-B has no matching lip there.
How they attach to the sedan
- SQ-A: automotive 3M double-sided tape and no drilling, so the sills must be clean and dry before the skirts go on.
- SQ-B: fixed at the OEM mounting points with the factory hardware, again without drilling.
- MP style: no method on the listing. Text 609-525-4865 and we'll tell you before you order.
Both SQ listings recommend a professional installer for alignment. If your G90 has the M Carbon package, the roof, the mirror caps and the trunk spoiler are already carbon, and carbon skirts take that theme lower down the car. Test-fit before painting or fitting: installed parts can't be returned, but our fitment guarantee covers return shipping if a skirt doesn't fit the car on its product page and you contact us first.
Frequently asked questions
Do G90 M5 side skirts fit a G60 5 Series or i5 M60?
No. BMW gave the M5 a bespoke side frame and much wider tracks than the regular 5 Series, so its sills are a different shape from a G60 540i or an i5 M60. Every skirt here is listed for the G90 M5 and the G99 M5 Touring only. For the rest of the M5 range, see the G90 M5 parts page.
Can I mix side skirt and front lip styles on a G90?
You can, since each part fits on its own. If you want the car to look planned, match the names: the MP and SQ-A skirts both have a lip in the same style. SQ-B skirts have no matching lip in our range, so compare photos and pick whichever lip suits them.
Do I need a professional to fit G90 side skirts?
We recommend one. The SQ-A and SQ-B listings both advise a professional fit for alignment, even though neither needs drilling. A shop can test-fit each skirt and line it up with the wheel arches before anything is stuck or fastened, which matters because installed parts can't be returned.
