Iron GiroDisc Upgraded Rotors

GiroDisc iron rotors for the Porsche 718 Boxster/Cayman S and GTS, a direct replacement for the factory disc that includes the caliper spacers needed to fit its slightly larger 350mm diameter (versus the OEM 330mm), for more braking force and cooling capacity. The hat is US-sourced 6061-T6 aircraft-spec aluminium and the disc is proprietary cast iron poured and machined in-house by GiroDisc, with a curved-vane design that pumps cooling air through the disc as it spins. A floating mount of drive pins lets the disc grow with heat and self-centre against the pads, with anti-noise spring washers to stop the rattle floating rotors are known for. Sold and priced in pairs; choose front or rear when ordering.
