The Helmet ST6 GT 3X-Large White Composite SA2025 by STILO represents the pinnacle of motorsport head protection for drivers who demand FIA-certified safety without compromise. Designed for high-performance road racing, circuit competition, and advanced driving applications, this helmet meets SA2025 standards—the latest safety specification governing impact absorption, retention, and structural integrity. Whether you're upgrading your race rig for a track day or building a dedicated competition vehicle, this GT-series helmet delivers the protection your neck and skull deserve during sustained lateral G-forces and frontal impact scenarios.
Built with a white composite shell construction, the ST6 GT combines lightweight fiberglass-reinforced polymer with energy-absorbing foam liner technology to manage impact loads while minimizing inertial stress. The 3X-Large sizing ensures proper fitment for larger head dimensions, critical because an ill-fitting helmet reduces padding contact and compromises safety margins during accident conditions. At 5.495 lbs, this helmet balances structural rigidity with comfort for extended wear during multi-hour endurance events, reducing neck fatigue that can impair driver performance. STILO's composite layering resists flexing and deformation under repeated stress, maintaining consistent protective geometry lap after lap.
This helmet suits drivers competing in sanctioned road racing, club-level circuit events, and performance driving schools that enforce current FIA specifications. The white finish pairs well with custom livery and interior trim in modern sport and race vehicles, from turbocharged street builds to full-cage track machines. Before purchase, verify your head circumference against STILO's 3X-Large fit chart—proper helmet selection is non-negotiable for safety and regulatory compliance. Compatible with most modern helmet communication systems and cooling accessories, the ST6 GT integrates seamlessly into a complete safety package alongside fire suits, harnesses, and HANS-device setups.
