With its titanium finish, aggressive HP6-derived design, and wide eye port for visibility in tight cockpits, this is the helmet for those who treat every lap like a qualifying session. The GT6 RD 4C\/EC is ready for IMSA communication and hydration systems right out of the box—because seconds count, even off the throttle.\u003c\/p\u003e\n\u003ch2\u003e4C: Carbon Composite 4 Layer Construction\u003c\/h2\u003e\n\u003cp\u003eOn Bell helmets, “4C” stands for “Carbon Composite 4 Layer Construction.” It refers to the shell technology Bell uses: a 4-layer carbon composite laminate. This blend typically combines carbon fiber with other advanced fibers (like Kevlar® or fiberglass) in multiple layers.\u003c\/p\u003e\n\u003cp\u003eThe purpose is to deliver a shell that is lighter than fiberglass alone, but more affordable and versatile than Bell’s top-end full carbon HP series shells (like HP7 or HP77 which use pure carbon\/advanced aerospace layups). In the case of this Carbon-4C\/EC model, the helmet is a Carbon Composite 4-layer shell with EC (electronic comms) kit integration.\u003c\/p\u003e\n\u003ch2\u003eBell GT6 RD 4C\/EC Helmet Features\u003c\/h2\u003e\n\u003cp style=\"padding-left: 40px;\"\u003e\u003cb\u003eIntegrated IMSA Radio \u0026amp; Hydration System:\u003c\/b\u003e Comes pre-installed with electronics and tubing for plug-and-play connection to your team’s radio and drink system.\u003c\/p\u003e\n\u003cp style=\"padding-left: 40px;\"\u003e\u003cb\u003e4C\/EC Carbon-Glass Composite Shell:\u003c\/b\u003e Lightweight and high-strength, built from premium carbon-glass for optimal energy absorption and all-day wearability in long stints.\u003c\/p\u003e\n\u003cp style=\"padding-left: 40px;\"\u003e\u003cb\u003eZeroNoise® Advanced Electronics:\u003c\/b\u003e Equipped with high-power speakers, a noise-canceling microphone, and superior sound insulation for crisp in-car communication even in loud environments.\u003c\/p\u003e\n\u003cp style=\"padding-left: 40px;\"\u003e\u003cb\u003eWide Eyeport:\u003c\/b\u003e Offers exceptional lateral and vertical visibility, ideal for closed-cockpit racing where every degree of vision matters.\u003c\/p\u003e\n\u003cp style=\"padding-left: 40px;\"\u003e\u003cb\u003eTrack-Proven Ventilation:\u003c\/b\u003e Strategically placed intake ports can be connected to cooling systems for maximum airflow in hot race conditions.\u003c\/p\u003e\n\u003cp style=\"padding-left: 40px;\"\u003e\u003cb\u003eStandards:\u003c\/b\u003e Dual certified to FIA 8859-2015 and Snell SA2020 for maximum track-day and competition eligibility.\u003c\/p\u003e\n\u003ch2\u003eBell GT6 RD 4C\/EC Helmet Size Chart\u003c\/h2\u003e\n\u003cp\u003e\u003cimg alt=\"Bell GT6 Pro Helmet SA2020 - Competition Motorsport\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0647\/9242\/8763\/files\/Bell_Auto_Racing_helmet-Size_Chart.jpg?v=1762268280\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt='\"Get Ahead with the Bell GT6 Carbon Racing Helmet - Uncompromised Quality and Style\"' src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0647\/9242\/8763\/files\/HelmetSizingButton_480x480.png?v=1678311769\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/p\u003e\n\u003ch2\u003eBell Racing GT6 RD Carbon 4C\/EC Helmet FAQs\u003c\/h2\u003e\n\u003cp\u003e\u003cb\u003eWhat’s the difference between the GT6 and the GT6 RD?\u003c\/b\u003e The GT6 RD includes factory-installed IMSA radio comms and hydration ports, while the standard GT6 does not.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eIs this compatible with ear buds or over-ear speakers?\u003c\/b\u003e Yes, the 4C version supports both ear cups and ear buds depending on your personal or team setup.
