G82/G83 M4
8 products
Carbon fiber parts for the BMW G82 M4 coupe and G83 M4 convertible, from front splitters to trunk spoilers and diffusers. Most are pre-preg dry carbon with a gloss clear coat, and because the M4 shares its front end with the M3, you get the full choice of splitters and grilles, including our own SPL1 OEM++ and the one-piece SPL2.
At the back, the coupe has ducktail, CS-style, OEM-style and M4-style trunk spoilers, two dry carbon trunk lids including a CSL-style one, and M4-specific rear corners. The convertible gets its own spoiler. Interior trim and engine bay pieces round out the range. Parts come with a 1-year warranty, and our fitment guarantee covers the car listed on each product page.
BMW G82/G83 M4 buying guide
Coupe or convertible?
The G82 coupe and G83 convertible share their nose and lower body, so most splitters, grilles, air ducts, side skirt extensions and rear corners are listed for both. Trunk-mounted parts are where they part ways. Most spoilers and both trunk lids on this page are coupe parts, and the convertible has its own M-style spoiler shaped for its trunk lid. The fitment line on each product page names the body style.
Choosing a rear spoiler
It comes down to how much of a statement you want. A ducktail lifts the trunk edge for a sharper profile. OEM-style, M4-style and CS-style lips stay close to BMW's own shapes. The MP-style and AD-style wings are for owners who want a proper wing. Our M4 rear spoiler buying guide compares the styles, and every option is under G82/G83 M4 spoilers.
Trunk lids
Two dry carbon trunk lids are listed for the G82 coupe, one of them CSL-style. They replace the factory lid rather than sitting on top of it, so plan on professional fitting. Check the product page for lead time and shipping before you order: a panel this size can take longer to arrive than a spoiler. See the M4 trunks.
Rear corners and diffusers
The M4's rear bumper corners differ from the M3's, so we list M4 versions with and without winglets, plus our own G82 rear corner extensions. The replacement corners swap for the factory gloss-black pieces, which unclip from the bumper. Pair them with the MP-style or Performance-style diffuser, or with our 3-piece diffuser, which comes with rear corner extensions for a finished look. Browse the M4 diffusers and rear corners.
Interior trim and build dates
M4s built from March 2023 have BMW's curved display, and the 2025 facelift (LCI) moved to iDrive 8.5, so dash and console trim comes in versions by build date. Choose the option that matches your car. If you're not sure, text a photo of your dashboard to 609-525-4865.

Test-fit every part before you paint, drill or install it. If something doesn't fit the car listed on its product page, contact us first and our fitment guarantee covers the return shipping. Installed parts can't be returned.
