Widebody Kit on the BMW M5 (F90), What to Expect
The F90 M5 is BMW's twin-turbo V8 super-sedan — 600-plus horsepower, all-wheel drive with a rear-drive mode, and a body that hides its pace almost too well. A widebody F90 fixes exactly that: wider arches over a broader footprint, deeper front aero and a dropped stance that turns the executive sleeper into something visibly serious. The F90 widebody scene is carbon-and-fabrication led rather than a single famous kit — carbon aero programs sharpen the bumpers, splitters and diffuser, while the wide-arch work itself is typically custom or small-batch. The S63 engine's enormous tuning headroom means most wide F90s carry four-figure-adjacent power too — a genuine autobahn weapon wearing the width to match.
Budgeting a M5 (F90) Widebody Kit Build
Budget an F90 widebody as bodywork-plus-aero rather than a catalogue kit. Custom or small-batch arch work runs $3,000–$7,000 in fabrication before $2,500–$5,000 of paint and blending on the big sedan panels; carbon aero (front lip, splitters, diffuser, ducktail) adds $2,000–$6,000 depending on how much of the car it covers. The F90's 5x112 bolt pattern and staggered 20in factory wheels point builds to wide forged 20–21in wheels with aggressive offset, filled flush to the new arches over a coilover or air drop. Since the S63 responds hard to tuning, many builds pair the width with power upgrades. A finished widebody F90 typically lands in the $8,000–$18,000 range before any engine work.
Preview your M5 (F90) before the build starts
On a big executive sedan, arch width, wheel offset and ride height decide whether the widebody reads factory-plausible or bolted-on. Rendering your exact F90, in your colour and wheel spec, before a shop starts fabricating arches tells you which direction suits it. TunedRides does it in about 30 seconds.
