The rings use Girodisc proprietary cast iron, poured in the USA and machined in-house for tight tolerances. A floating mount system with ten high-strength alloy steel drive pins, cadmium plated for corrosion resistance, controls axial and radial float between the hat and ring. Class 12.9 cap screws with hardened washers secure the assembly. Anti-noise spring washers permit thermal expansion while minimising cold rattle and helping the rotor self-centre between pads.\u003c\/p\u003e\n\n  \u003ch3\u003eSpecifications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eOuter diameter: 380 mm\u003c\/li\u003e\n    \u003cli\u003eOverall height: 63 mm\u003c\/li\u003e\n    \u003cli\u003eThickness: 32.0 mm new - 30.0 mm minimum\u003c\/li\u003e\n    \u003cli\u003eType: Vented two-piece floating\u003c\/li\u003e\n    \u003cli\u003eFace: Slotted with zinc coating\u003c\/li\u003e\n    \u003cli\u003eVane design: Curved vane\u003c\/li\u003e\n    \u003cli\u003eMaterials: Cast iron ring with 6061-T6 aluminium hat\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eVehicle fitment\u003c\/h3\u003e\n  \u003cp\u003eFor BMW models equipped with blue Brembo calipers and iron discs:\u003c\/p\u003e\n  \u003cul\u003e\n    \u003cli\u003eBMW M3 F80 Saloon - S55\u003c\/li\u003e\n    \u003cli\u003eBMW M4 F82 Coupe - S55\u003c\/li\u003e\n    \u003cli\u003eBMW M4 F83 Convertible - S55\u003c\/li\u003e\n    \u003cli\u003eBMW M2 F87 LCI - N55\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003cp\u003e\u003cstrong\u003eNot compatible\u003c\/strong\u003e with cars using red, silver or gold calipers, or carbon ceramic brake systems.\u003c\/p\u003e\n\n  \u003ch3\u003eWhat is included\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e1 x pair of Girodisc front 380 mm two-piece slotted floating rotors\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003ePart number\u003c\/h3\u003e\n  \u003cp\u003e\u003cstrong\u003eA1-186\u003c\/strong\u003e\u003c\/p\u003e\n\n  \u003ch3\u003eProfessional fitting and support\u003c\/h3\u003e\n  \u003cp\u003eInstallation by a qualified technician is recommended.
