Designed specifically for the 2014–2019 991.1 and 991.2 GT3\/GT3 RS chassis, this cage integrates with the car's factory hard points and interior geometry for a fitment that respects the car's original engineering.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eOverview \u0026amp; Important Note on Materials\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eBefore detailing specs, it's worth being transparent about something important: \u003cstrong\u003efull carbon fiber roll cages are rare in the market, and for good reason.\u003c\/strong\u003e Most reputable roll cage manufacturers (Autopower, Custom Cages, StudRack, RSS, Agency Power body components aside) build primary roll cages from \u003cstrong\u003echromoly or DOM steel tubing\u003c\/strong\u003e, not carbon fiber, because:\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCarbon fiber's failure mode under impact is sudden and catastrophic (shattering\/delamination) rather than the progressive, energy-absorbing bend of steel or chromoly tubing\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMost motorsport sanctioning bodies (FIA, SCCA, NASA, PCA) either prohibit carbon fiber as a primary cage material or require it be paired with a certified steel structure\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWeight savings on a cage are usually achieved through chromoly (lighter and stronger than mild steel) rather than by moving to composite tubing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eIf what you're looking at is marketed as a \"carbon fiber roll cage,\" it's worth confirming with the seller whether that means:\u003c\/p\u003e\n\u003col class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-decimal flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eA \u003cstrong\u003esteel\/chromoly cage with a carbon fiber aesthetic wrap or sleeve\u003c\/strong\u003e on visible tubing (common for interior show-quality builds)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eA \u003cstrong\u003ecarbon fiber halo\/harness bar\u003c\/strong\u003e (partial, non-structural, e.g., a rear brace) rather than a full cage\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAn actual composite tube cage (rare, typically custom-fabricated, and likely not certified for competition use)\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eI'd rather flag this now than write a polished spec sheet implying a full structural carbon cage is a standard, safety-certified product — that's the kind of detail that actually matters if you or someone else is relying on it in a crash.\u003c\/p\u003e","brand":"eurobahndynamics","offers":[{"title":"Default Title","offer_id":48401114038513,"sku":null,"price":14999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0604\/7406\/5137\/files\/H261dbee564014b67837efb37d0d7da9cU.jpg?v=1783904897","url":"https:\/\/eurobahndynamics.com\/products\/porsche-911-991-gt3-gt3rs-carbon-fiber-roll-cage","provider":"eurobahndynamics","version":"1.0","type":"link"}
