BMW G82 M4 CSL carbon fiber rear trunk with integrated ducktail spoiler by CarbonXtreme

BMW G82 M4

BMW G82 M4 carbon-fiber upgrade hub by CarbonXtreme — performance-focused components with OEM-grade fitment and a refined finish. Discover front lip / front splitter / front lip spoiler, rear diffuser, side skirt / side skirt extensions, front grille / center grille, intake / ram-air intake, engine bay covers, mirror caps, wings / spoilers / trunk lid (boot lid), hood (bonnet) and underbody panels engineered around prepreg dry carbon, autoclave curing, PPG clear coat and OEM CAD development. Tuned to clear factory tolerances for both daily use and track-focused builds on the M4 coupe.

This is where an M4 stops looking “stock” and starts feeling yours. Your choices—styles, pairings, wheel designs and colors—don’t follow rules; they mirror your taste and the M4’s coupe silhouette. CarbonXtreme dry-carbon adds that quietly unmistakable premium: a clean, consistent weave with sharp, glass-like reflections, finished in PPG clear coat and mounted with OEM-logic precision. Even non-enthusiasts recognize it as truly high-end at a glance. Pick what speaks to you—front lip + diffuser, grille + intakes, wing + trunk lid—and let every walk-up deliver that “new-again” thrill.
