Extreme Online Store's complete 2021-Up BMW G82 M4 Coupe and G83 M4 Convertible catalog — carbon fiber exterior trim and exhaust systems, designed and test-fitted on the M4. Engines across the range: the 3.0L S58 twin-turbo inline-six, 473 hp in the base M4, 503 hp in the Competition and 543 hp in the CSL.
Coupe and convertible share the front end, so splitters, grilles and hood parts fit both; decklid and roof parts are body-specific. The G80 M3 shares the front fascia, so most G82 front pieces also fit the M3. Use the Category row on the left to go straight to a part type; each listing states the exact trims and model years it fits.
Shop by category: Exterior Trim, Exhaust Systems.
Materials run carbon fiber, dry carbon fiber, ABS plastic and T304 stainless for exhaust. Every carbon fiber part is UV clear-coated for outdoor use; ABS and polypropylene parts ship primed or finished as listed.
Frequently asked
Do you ship free? Yes — free shipping to the 48 contiguous states on every M4 part.
Are these direct fit? Every part here is designed on the actual car and confirmed for fitment. Installation notes and hardware requirements are on each product page.
Carbon fiber or ABS? Carbon fiber is lighter and stiffer with a visible weave under clear coat. ABS is more impact-tolerant and usually ships primed or gloss black — a good choice for splitters that may see driveway contact.
