Designed to improve thermal management, durability, and braking consistency, the system utilizes a fully floating rotor configuration engineered for demanding street and track applications.\u003c\/p\u003e \u003cp\u003eThe rotor assembly incorporates a lightweight aluminum hat and a cast iron disc connected through a floating mount system utilizing 10 high-strength alloy steel drive pins. These cadmium-plated pins transfer braking loads while allowing controlled axial and radial float between the rotor and hat. Anti-noise spring washers minimize cold rotor rattle while maintaining the freedom required for thermal expansion and self-centering between the brake pads.\u003c\/p\u003e \u003cp\u003eWhen combined with performance brake pads and high-temperature brake fluid, the system helps reduce the risk of brake fade, rotor distortion, and overheating during demanding driving conditions. Once installed, only the cast iron rotor ring requires replacement during future servicing.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eTwo-piece floating front brake rotor system\u003c\/li\u003e \u003cli\u003eDesigned for PORSCHE 991 Turbo, 991 Turbo S, and Cayman GT4\u003c\/li\u003e \u003cli\u003eFully floating mount design with 10 drive pins\u003c\/li\u003e \u003cli\u003eHigh-strength alloy steel drive pins with cadmium coating\u003c\/li\u003e \u003cli\u003eAnti-noise spring washers reduce cold rotor noise\u003c\/li\u003e \u003cli\u003eAllows thermal expansion while maintaining rotor alignment\u003c\/li\u003e \u003cli\u003eSelf-centering rotor design between brake pads\u003c\/li\u003e \u003cli\u003eStraight slotted friction surface\u003c\/li\u003e \u003cli\u003eCurved vane internal ventilation design\u003c\/li\u003e \u003cli\u003eServiceable system with replaceable rotor rings\u003c\/li\u003e \u003cli\u003eSuitable for high-performance street and track use\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eSpecifications:\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eDisc Diameter: 380 mm\u003c\/li\u003e \u003cli\u003eDisc Thickness (New): 34.0 mm\u003c\/li\u003e \u003cli\u003eMinimum Disc Thickness: 32.0 mm\u003c\/li\u003e \u003cli\u003eDisc Height: 69.3 mm\u003c\/li\u003e \u003cli\u003eDisc Finish: Straight Slotted\u003c\/li\u003e \u003cli\u003eVane Design: Curved Vane\u003c\/li\u003e \u003cli\u003eDisc Type: Vented\u003c\/li\u003e \u003cli\u003eDisc Material: Cast Iron\u003c\/li\u003e \u003cli\u003eMounting System: Floating two-piece construction\u003c\/li\u003e \u003cli\u003eCenter Lock Compatibility: Optional drive pin configuration available\u003c\/li\u003e \u003cli\u003eQuantity: Sold as a pair\u003c\/li\u003e \u003c\/ul\u003e ","brand":"GIRODISC","offers":[{"title":"Default Title","offer_id":43818812047540,"sku":"A1-066","price":2228.28,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/2605\/3812\/files\/brake-rotor-kit_5f7c1e99-ba9c-4910-b0ec-1e362f7894db.jpg?v=1780890708","url":"https:\/\/atomic-shop.eu\/products\/girodisc-a1-066-front-brake-rotor-kit-380x34-mm-for-porsche-991-turbo-s-cayman-gt4","provider":"ATOMIC-SHOP Performance Parts \u0026 Motorsport Equipment - EU","version":"1.0","type":"link"}
