Developed from motorsport applications, these vanes act as a centrifugal pump, drawing air through the rotor and directing it outward. The larger 350mm rotor diameter provides additional capacity for heat dissipation compared with the original 330mm configuration.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe center hats are manufactured from \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003eU.S.-sourced 6061-T6 aircraft-grade aluminum\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e, combining lightweight construction with the strength required for high-performance braking.
