Three generations, three completely different engines, and one reputation that's never wavered: the M5 has been the super-saloon to beat since the E60's V10 first turned heads in 2005. That car gave way to the twin-turbo F10, and the current G30-based F90 has carried the name into the AWD era. What's stayed consistent through all of it is how well the M5 responds to styling work — it's a big, purposeful shape to begin with, and the right splitter, skirt or spoiler just sharpens what's already there rather than fighting it.
It's also, generation for generation, one of the best-supported M cars in our range. Splitters, side skirts, spoilers and diffusers are stocked across all three cars, which means whichever M5 is sitting on your driveway, there's a genuine path to a finished look rather than a compromise.
Front Splitters
Splitter fitment on the M5 is more particular than on most cars we cover, and it's worth getting right before you order. We stock F10/F11 splitters in both ABS gloss black and carbon fibre, with separate listings for M Sport and non-M Sport bumpers, plus a G30/G31 pre-LCI splitter for the current generation. The M Sport vs standard bumper split matters because the two use genuinely different lower bumper openings — a splitter built for the M Sport car simply won't seat correctly on a standard bumper, and it's the single most common fitment mix-up we see on this model.
Side Skirts
Side skirts are the part that quietly does the most work on an M5. On their own they don't look like much in a product photo, but fitted to the car they run the full length of the sill and visually tie the front splitter into the rear diffuser — without them, a splitter and diffuser can end up looking like two separate upgrades rather than one cohesive kit. We stock gloss black skirt extensions for both the F10/F11 and G30/G31.
Rear Spoilers
This is where the three generations really show their character. The E60 gets a gloss black boot spoiler true to the original car's cleaner lines. The F10 has both ABS gloss black and carbon fibre options for owners who want to match a carbon splitter. The G30 gets something genuinely different: a CS-style carbon fibre spoiler that slopes at the ends rather than sitting flat across the boot, which is the shape most current M5 owners are specifically chasing when they get in touch.
Rear Diffusers
For the F10 M Sport bumper, we stock a rear valance diffuser in a standard gloss black finish and a carbon fibre quad-exit design for owners running a full carbon look front to back. Paired with the matching splitter and side skirts, this is the combination that gets an M5 closest to looking like a factory Competition-spec car rather than a standard 5 Series with parts bolted on.
Choosing a Finish Across a Full Kit
The mistake we see most often on the M5 isn't a wrong part — it's a mismatched set. Because splitters, skirts, spoilers and diffusers are often bought separately over time, it's easy to end up with a gloss black splitter and a carbon spoiler that never quite look like they belong to the same car. If you're planning to build the full look eventually, it's worth deciding on gloss black or carbon fibre pattern up front and buying to that plan, even if the parts arrive months apart.
Fitting Notes
Side skirts and diffusers fit using the sill and bumper's existing mounting points along with automotive-grade double-sided tape on the contact edges, and splitters need the front bumper pulled forward enough to get clean access underneath. None of this requires cutting into the bumper or sills on a standard car, but a full four-part kit fitted properly in one sitting is a job most owners hand to a bodyshop rather than tackling on a driveway, simply because of how much has to come off the car to do it right.
E60 vs F10 vs G30: What Changes
Each generation uses a completely different bumper and boot profile, so parts genuinely do not cross over between them — there's no shortcut here. The E60 (2003-2010) is the V10 original and the cleanest shape of the three. The F10 (2011-2016) introduced turbocharging and a noticeably more aggressive M Sport bodykit, which is also where the M Sport vs standard bumper split starts to matter. The G30-based F90 (2017+) is the current car, and it's the one with the sloped CS-style rear wing available. Match your splitter and diffuser to your exact bumper, since M Sport and non-M Sport 5 Series bumpers on the same F10 chassis are not interchangeable with each other, let alone across generations.
Frequently Asked Questions
Can I fit side skirts without removing the wheels?
It's possible on some cars, but you'll get a far cleaner fit — and less risk of scuffing the paint above the sill — if the front wheels are off or at least turned fully and the car is raised enough to work along the full sill length.
Will a carbon fibre splitter match my carbon mirror caps exactly?
The pattern and weave are generally a close match across most carbon-effect ABS parts, but because these come from different production runs, we'd always recommend checking current product photos against your existing parts before ordering if an exact match matters to you.
Does the G30 CS-style spoiler fit the standard F90 M5 as well as the Competition?
Yes — it's designed around the G30/G31 boot lid shape, which is shared across the standard and Competition M5, so trim level doesn't affect fitment here.
What's the difference between the two F10 diffuser options?
The standard gloss black version is a cleaner, single-finish look, while the quad-exit carbon fibre version is designed for owners running a carbon splitter and skirts who want the diffuser to match rather than stand apart in gloss black.
