About Seibon Carbon

When it comes to carbon fiber automotive body components, few names carry as much weight as Seibon Carbon. A division of Seibon International, Inc., the brand has been a cornerstone of the performance aftermarket since its founding in 2003 — built from the ground up by genuine automotive enthusiasts who saw a gap in the market for truly high-quality, durable carbon fiber parts.

Seibon's catalog spans the full exterior of sport compact and performance vehicles, from carbon fiber hoods and hood panels to lightweight doors, rear spoilers, and trunk lids. Whether you're building a dedicated time-attack car, a show vehicle, or simply want to shave weight without sacrificing aesthetics, Seibon has a fitment-tested solution.

What Sets Seibon Apart

Not all carbon fiber is created equal. Seibon uses only the highest-grade raw materials and constructs every component using a one-piece carbon sheet — a critical detail that ensures a consistent weave pattern without the broken lines or mismatched panels common in lesser products. Their production processes achieve an exceptional carbon-to-resin ratio, resulting in components with superior stiffness and strength.

Seibon offers two distinct production methods to suit different applications. Their traditional wet-lay and vacuum-infused components deliver an outstanding balance of weight savings, visual appeal, and value. For racers demanding the absolute best, Seibon's proprietary dry carbon process — using pre-impregnated (pre-preg) epoxy materials — can yield up to 70% weight savings compared to OEM steel panels, with exceptional weave consistency even around complex geometry and tight bends.

Every Seibon product is backed by both a fitment guarantee and a clear-coat warranty, reflecting the brand's confidence in its multi-step quality control process. All parts are test-fitted before being made available for sale, and molds are developed in-house to maintain precise tolerances across production runs.

Built for Enthusiasts, Recognized Worldwide

Seibon Carbon's reputation extends well beyond the garage. Their components have appeared in television shows, major motion pictures, and at high-profile racing events — a testament to the quality and visual impact of their work. The brand is a proud member of the Specialty Equipment Manufacturers Association (SEMA) and maintains an active dealer network spanning the United States, Canada, Europe, Asia, and the Middle East.

With applications covering Japanese, European, and American sport compacts — from hatchbacks and sedans to pickup trucks and SUVs — Seibon continues to expand its lineup to serve a growing global community of performance enthusiasts.
