Built as a two-piece floating rotor system, it combines PFC’s precision-machined aluminum hat with a high-carbon alloy rotor ring, joined through the patented V3 attachment system. This hardware-free design allows the disc to float both radially and laterally, reducing thermal stress, vibration, and pedal pulsation.\u003c\/p\u003e\n\u003cp\u003eSlotted rotor rings improve bite, shed gases, and enhance pad refresh for consistent stopping power during repeated heavy braking. The directional vane system is turned on both the inner and outer surfaces for superior airflow, maximizing heat dissipation and keeping brake temps under control. Manufactured to extreme tolerances—runout under 0.001\" and thickness variation under 0.0003\"—the V3 system ensures smooth, stable braking with minimal NVH.\u003c\/p\u003e\n\u003cp\u003eServiceability is built in: when the rotor ring wears, the hat can be reused, and replacement discs are easily installed thanks to the simplified attachment system. Designed specifically for Porsche 997\/991 Turbo applications, this assembly is ideal for track days, endurance racing, and aggressive street driving where heat management and stopping power are critical.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003e\u003cspan class=\"accordion__toggle h6\"\u003e\u003cspan class=\"text-with-icon gap-4\"\u003eTechnical Details\u003c\/span\u003e\u003cspan class=\"animated-plus group-expanded:rotate\" aria-hidden=\"true\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cdiv class=\"accordion__content prose\"\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine PFC part # 379.069.63 – Left side rotor\/hat assembly for Porsche 997\/991 Turbo\u003c\/li\u003e\n\u003cli\u003eTwo-piece floating system with patented V3 attachment (no hardware) for reduced stress and vibration\u003c\/li\u003e\n\u003cli\u003eSlotted rotor rings for improved pad bite, gas evacuation, and consistent performance\u003c\/li\u003e\n\u003cli\u003eHigh-carbon alloy rotor disc with copper\/molybdenum for high-temperature strength\u003c\/li\u003e\n\u003cli\u003ePrecision-machined vanes (inner \u0026amp; outer) for enhanced airflow and cooling efficiency\u003c\/li\u003e\n\u003cli\u003eTight tolerances: runout \u0026lt; 0.001\", thickness variation \u0026lt; 0.0003\"\u003c\/li\u003e\n\u003cli\u003eReusable hat for cost-effective long-term service—replace only the rotor rings when worn\u003c\/li\u003e\n\u003cli\u003eDirect fitment for Porsche 997\/991 Turbo factory calipers, no modification required\u003c\/li\u003e\n\u003cli\u003eIdeal for high-performance street, track days, time attack, and endurance racing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCommon Vehicle Fitments:\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003cdiv class=\"table-scroller\"\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr data-cow-cart-observed=\"true\"\u003e\n\u003ctd\u003ePorsche\u003c\/td\u003e\n\u003ctd\u003e991 Turbo, Turbo S\u003c\/td\u003e\n\u003ctd\u003e2013-2019\u003c\/td\u003e\n\u003ctd\u003eFront\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr data-cow-cart-observed=\"true\"\u003e\n\u003ctd\u003e \u003c\/td\u003e\n\u003ctd\u003e997 Turbo\u003c\/td\u003e\n\u003ctd\u003e2004-2013\u003c\/td\u003e\n\u003ctd\u003eFront\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/figure\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"OGR Dealer","offers":[{"title":"Default Title","offer_id":53614290698421,"sku":"PF37906963","price":982.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/4844\/4597\/files\/v3-slotted-web_3.jpg?v=1793104171","url":"https:\/\/naroescapemotorsports.com\/products\/pfc-v3-slotted-rotor-hat-assembly-left-porsche-997-991-turbo","provider":"Naroescape Motorsports","version":"1.0","type":"link"}
