Popularization of domestic dry carbon technology reshapes the pricing system of tuning kits for BMW, Mercedes-Benz and Porsche.

The large-scale popularization of prepreg dry carbon manufacturing technology has greatly cut production costs for domestic tuning part manufacturers. Retail prices of full carbon fiber aerodynamic kits for BMW, Mercedes-Benz, Audi and Porsche have dropped by 40% compared with two years ago. Carbon fiber tuning has evolved from a niche luxury consumption to mass mainstream demand, and industry competition has shifted from price wars to comprehensive competition over craftsmanship, fitting accuracy and after-sales service.

In the past, core production equipment for dry carbon kits relied entirely on imports, with a single production line investment exceeding ten million RMB, leaving only a handful of large manufacturers capable of mass production.

Now domestic machinery suppliers have launched localized carbon fiber hot-pressing equipment, enabling small and medium-sized tuning factories to launch production. The industry’s total dry carbon output capacity has doubled, while low-end wet carbon products are gradually phased out.

Process upgrades deliver all-round product improvements: dry carbon components feature higher density and lighter weight, with coatings resistant to yellowing and cracking. Integral molding eliminates splicing gaps, requiring minimal grinding and touch-up after installation and significantly cutting labor costs for tuning shops.

The product range covers full exterior parts including hoods for BMW M series, side skirts for Mercedes-AMG, rear wings for Porsche 992 and front splitters for Audi RS, alongside supplementary carbon fiber interior trims, steering wheels and center console panels to enrich product portfolios.

Market shifts force manufacturers to transform: profit margins keep shrinking for OEM factories that only rely on low-price bulk sales, while branded manufacturers with independent vehicle-specific mold development, real-car testing and official warranties maintain steady gross profit. Multiple leading brands offer lifetime coating repair services to differentiate themselves from low-end unguaranteed products and build competitive advantages.

Carbon fiber components for new energy vehicles stand out as a new growth driver. Manufacturers develop lightweight aerodynamic carbon fiber parts for BMW i and all-electric Porsche models, balancing stylish appearance and optimized driving range.
