Rather than reinventing what already works, 034Motorsport developed these 2-Piece Floating Rear Brake Rotors to improve the areas that matter most to enthusiasts who regularly drive their GT3 on the street and the track: durability, serviceability, and long-term value. \u003cbr\u003e\u003cbr\u003e Designed specifically for the 991 GT3, these rotors feature a floating 2-piece design with premium CM-250 special alloy iron rotor rings, aerospace-grade aluminum hats, and a fully floating bobbin mounting system. Increased thermal mass improves heat capacity for exceptional resistance to repeated high-temperature braking, while the 72-curved-vane cooling design, J-slotted friction surfaces, and temperature-indicating paint provide the performance and feedback demanded during spirited driving and track use. \u003cbr\u003e\u003cbr\u003e Compatible with everything from factory Porsche brake pads to the most aggressive racing compounds, these rotors are engineered to deliver consistent braking performance through countless heat cycles. \u003cbr\u003e\u003cbr\u003e When service is required, the replaceable rotor rings allow the aluminum hats to be reused, reducing replacement costs to approximately half that of OEM Porsche rotors while maintaining factory fitment and functionality. \u003cbr\u003e\u003cbr\u003e For drivers who use their GT3 as Porsche intended, 034Motorsport's 2-Piece Floating Rear Brake Rotors deliver exceptional durability, increased thermal capacity, and lower long-term ownership costs without compromise. \u003c\/p\u003e \u003cdiv class=\"widget block block-static-block\"\u003e \u003cdiv class=\"col-2\"\u003e \u003cdiv class=\"col2-set\"\u003e \u003cdiv class=\"col-1\"\u003e \u003cdiv class=\"std\"\u003e \u003ch3\u003eTemperature-Indicating Paint Marks:\u003c\/h3\u003e \u003cimg class=\"lt-hide\" style=\"max-width: 100%; height: auto; margin: 0 auto 16px auto;\" src=\"https:\/\/www.034motorsport.com\/media\/wysiwyg\/2pc-rotor-temp-marks.jpg\" alt=\"2-Piece Rotors\"\u003e \u003cp\u003e034Motorsport 2-Piece Performance Brake Rotors feature temperature-indicating paint marks on the rotor edge that provide a quick visual reference for heat exposure during aggressive street driving, autocross, or track use. \u003cbr\u003e\u003cbr\u003eThe paint changes color at specific temperature thresholds to help drivers understand operating conditions:\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003cstrong\u003eGreen → White at 478°C (892°F)\u003c\/strong\u003e\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003eOrange → Yellow at 571°C (1060°F)\u003c\/strong\u003e\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003eRed → White at 640°C (1184°F)\u003c\/strong\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eIf the \u003cstrong\u003ered paint turns white throughout\u003c\/strong\u003e, the rotors are consistently operating beyond their intended temperature range.
